Antistatic Precautions
This section describes the procedure to prevent damage to the QSR system from static electricity.
CAUTION (1) When handling router modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.
Use these precautions to prevent damage from static electricity:
- Do not handle modules unless you are using the appropriate antistatic protection, such as an antistatic wrist or heel strap and a conductive mat.
- When using an antistatic wrist strap, attach the cord to the appropriate ground jack
- Handle modules by outer enclosure only. Do not touch electrical connections, pins, or soldered surfaces.

QSR Module Population Rules
Each QSR chassis provides a single chassis with 10 slots to house route controller and router modules. The chassis accepts one or two route controller modules and up to nine router modules in a one chassis system. Additional chassis may be populated with up to ten router modules. Route controller modules can reside only in slots 10 and 1 (10 and 1). In a QSR chassis with only one route controller module, install the route controller module in slot 10. Figure 2 shows QSR chassis slot numbering when viewed from the front of the QSR.
NOTE The 2-Port Gigabit Ethernet module is a Family 1 module.
Figure 2. QSR Chassis Slot Numbering
Rules for populating a single QSR chassis are as follows:
- Install route controller modules in slots 10 and 1. The QSR accepts only NSR® Route Controller Modules.
- When only one route controller module is installed, install it in slot 10. Use slot 1 for a router or a filler module.
- Initial installation of two router modules is required in the first QSR chassis only.
- Every router module must be abutted by another router module, a route controller module, or a fabric filler module.
- For example, you plan to use only two router modules in the chassis and you install them in slots 5 and 6. Slots 4 and 7 must contain a fabric filler module.
- The remaining empty slots must contain standard filler modules.
- Or, your QSR contains a single route controller module in slot 10 and eight router modules in slots 2 through 8. Slot 1 must contain a fabric filler module.
- Fabric filler modules ensure multiple communications routes between installed modules.
NOTE Fabric filler modules differ from standard filler modules.
- Add a standard filler module to any empty slot in the chassis. During QSR operation, standard filler modules ensure proper cooling and eliminate electromagnetic interference.
- A module occupying a slot uses the slot number as its identifier.
- If installing the module in a cold chassis, follow the Population Rules outlined in the Quarter-rack Scalable Router Install Guide. The 2-Port Gigabit Ethernet module is a Family 1 module.
- If installing the router module in a live chassis use the show population CLI command - specifying the module family - to identify the slot to populate.
Refer to IPriori CLI Reference and Configuration Guides (Vol. 1) for further information on this command. Online versions of the manuals are available at http://www.avici.com/documentation.
CAUTION (2) When handling router modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.
Populating Multiple Chassis
Population rules for a second chassis that you plan to connect to the first chassis are similar to the rules for the first chassis. However, you must install a minimum of two router modules in the second and subsequent chassis. After installing the first two modules, you can continue to populate the chassis one module at a time, following the population rules in the preceding section.
A secondary chassis does not require a route controller module and can house up to 10 router modules. Place the last router module in slot 10.
Completely fill the first QSR chassis with router modules before starting to populate a second QSR that you plan to connect to the first.
In a multiple-chassis system, a module is identified by the chassis number and slot number; for example, 1/10 is chassis 1, slot 10.
Preparing to Remove a Router Module
Router module replacement requires shutting down the module via the CLI command line, disconnecting the cable connections, and removing the router module.
Routine router module removal requires the disconnecting of existing fiber optic cable connections. Router modules serving as Server Attached Modules (SAMs) require disconnecting fiber optic and Ethernet cable connections to the server module.
CAUTION (3) Within five minutes of removal of a module, a replacement module or filler module must be installed in the empty slot to ensure proper air flow within the system.
Removing a Router Module
Prior to removing a module you must shut down the module being replaced.
WARNING (1) This is a Class 1 laser product. Invisible laser radiation can be emitted from the aperture of the port when the fiber cable is disconnected. Avoid exposure to laser radiation and do not look directly into open apertures.
PROCEDURE: Use the following steps to remove the Gigabit Ethernet module(s):
Step 1 Verify that the wrist strap you are wearing is properly grounded.
Step 2 Open the pull tab on the right cable tray and gently pull the right cable tray out of the router (see Figure 3).
Figure 3. Router Module Faceplate
Step 3 Disconnect the lower fiber optic cables from the fiber cable adapters (SC) on the right cable tray. Move the cables to one side to ensure that they do not interfere with removal of the router module (see Figure 4).
Figure 4. Router Module Cable Connections
Step 4 Gently push the right cable tray back into the module and close the cable tray pull tab.
- If the module is a SAM, proceed to Step 5, if not, skip to Step 6.
Step 5 Open the cable tray pull tab on the faceplate of the router module tray marked "AUX." Gently pull the cable tray partially out of the module until detent clicks (see Figure 5).
Step 6 Open the pull tab on the center cable tray and gently pull the cable tray out of the router until detent clicks (see Figure 5).
Figure 5. Ethernet Cable Connection
Step 7 Disconnect and undress the RJ-45 Ethernet cable from the Ethernet port on the tray marked "AUX" (see Figure 5). Hang the Ethernet cable down and out of the way, or tuck the cable into the horizontal cable tray under the module shelf.
Step 8 Gently push all cable trays to the closed position and close the cable tray pull tabs.
WARNING (2) This is a Class 1 laser product. Invisible laser radiation can be emitted from the port aperture when the fiber cable is disconnected. Avoid exposure to laser radiation and do not look directly into open apertures
Step 9 To unlock the ejector latches, simultaneously slide the release levers in the direction of the arrows (see Figure 6).
CAUTION (4) When the ejector latch release lever is in the open position, do not use the latch lever to remove the module or adjust the module in the card guides. Failure to adhere to these guidelines may result in equipment damage.
Step 10 To release the module from the backplane, simultaneously rotate the ejector latches to a fully open position and carefully pull the router out a few inches out of the shelf (see Figure 6).
Figure 6. Router Module Ejector Release Levers
Step 11 Hold the module in place with one hand at the bottom of case, then close the ejector latches by rotating them to the closed position and sliding the release levers in the direction of the arrows to lock the levers back into place.
Step 12 To remove the module, grasp it on the top and bottom and pull it carefully out of the shelf.
NOTE Do not rest the module on the cable trays during inspection. This could result in the breaking of the pull tabs on the cable tray drawers (see Figure 3).
Step 13 Carefully inspect the Very High Density Metric (VHDM) connector for damage such as deformed sockets, holes between socket columns, and deformed guide fins on top and bottom of the socket columns.
CAUTION (5) Any contact to a VHDM connector outside a QSR could damage the connector. A detailed inspection of the VHDM connector is required each time a module is removed or inserted. Lay the module gently on its side to perform a VHDM connector inspection.
Figure 7. VHDM Connector
.
NOTE If the VHDM connector has any signs of damage, DO NOT insert it into a QSR. Mark the module and slot as damaged and call TSR-BY-AVICI to request an Return Material Authorization (RMA).
Step 14 Before placing the module in a static-proof bag, replace the VHDM protective cap over the VHDM connector at the rear of the module. This will protect the pins while the module is not in the QSR (see Figure 12). Repackage according to RMA directions. Ship back to Avici.
Step 15 If the slot is not populated with a module, it must be filled with a filler module within five minutes.
Removing Fabric Filler or Filler Modules
The QSR systems ships with five (5) filler modules that ensure proper cooling and elimination of electromagnetic interference during operation and two (2) fabric filler modules that ensure a robust and reliable topology between modules. Remove filler modules or fabric filler modules from slots intended for router modules.
Removing Fabric Filler Modules
If the slot intended for the route controller is filled with a filler or fabric filler module, remove it using the procedure below.
To avoid damage to the backplane, perform a detailed inspection of the fabric filler module VHDM connector each time you remove or insert a module.
PROCEDURE: Use the following procedure to remove a fabric filler module:
Step 1 Verify that the wrist strap you are wearing is properly grounded or that other antistatic measures are in place.
Step 2 To unlock the ejector latches on the module, simultaneously do the following to both latches (see Figure 9):
- Press release levers in the directions indicated by the arrows on the latch.
- Rotate the ejector latches away from the module faceplate.
Figure 8. Opening Fabric Filler Module Latches
Step 3 Pull the module out of the chassis to unseat the backplane connectors.
Step 4 Carefully inspect the VHDM connector for damage such as deformed sockets, holes between socket columns, or distorted guide fins on the top and bottom of the socket columns (see Figure 9).
Figure 9. Fabric Filler Module VHDM Connector
.
CAUTION (6) If the VHDM connector shows any signs of damage, DO NOT insert it into a chassis. Mark the module as damaged and call TSR-BY-AVICI to request an RMA.
Step 5 Close the ejector latch levers on the fabric filler module.
Removing Filler Modules
If the slot intended for the route controller is filled with a fabric filler module, remove it using the procedure below. Figure 10 shows a filler module.

PROCEDURE: Use the following steps to remove a filler module:
Step 1 Use a 1/2-in. flat-blade screw driver to loosen the lock latch on the filler module.
Step 2 Pull the filler module out of the slot (see Figure 11).
Figure 11. Removing Filler Modules
Step 3 Store the filler module in a dry, cool area.
Installing Router Modules
When replacing a router module or a filler module, installation must adhere to module population rules for your type of installation. Refer to the "QSR Module Population Rules" .
CAUTION (7) Fiber optic cables must be thoroughly cleaned each time a cable is connected or reconnected. Failure to do so may impact performance or damage to the fiber optic cable.
Installation of the Server Attached Module (SAM) requires the re-connection of fiber optic and Ethernet cables.
CAUTION (8) When handling modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.
PROCEDURE: Use the following procedure when installing a router module or a router module acting as a Server Attached Module (SAM):
Step 1 Verify that your antistatic wrist strap is properly grounded.
Step 2 Remove the router module from its packaging and static protection bag.
Step 3 Before inserting the module, remove the VHDM protective cap from the end of the module before use. Set the protective cap aside in a safe place (see Figure 12).
NOTE Do not rest the module on the cable trays during inspection. This could result in the breaking of the pull tabs on the cable tray drawers (see Figure 13).

Configuring Flow Control
The flowcontrol command provides for configuring the circumstances under which flowcontrol will be used.
Syntax: flowcontrol {asymmetric | symmetric}
no flowcontrol
Description: Flow control controls traffic rates during periods of congestion. Use the flowcontrol asymmetric command to allow the local port to determine whether flow control will be performed on the remote port. During periods of local port congestion, the local port will send a request for the remote port to stop transmitting.
Use the flowcontrol symmetric command to allow for the local port to only perform flow control if the remote port can also perform flow control. If the remote port is not able to perform flow control locally, the local port will also not perform flowcontrol.
Use the no flowcontrol to disable flow control on this interface.
Default: Symmetric.
Command Mode: Gigabit Ethernet interface configuration.
Example: The following set of commands:
- Uses the configure terminal command to enter configuration mode.
- Uses the interface gbe command to enter interface mode for Gigabit Ethernet for the specified port.
- Uses the flowcontrol asymmetric command to set flow control for this interface to asymmetric.

LEDs
The 2-Port Gigabit Ethernet module supports six LEDs, see Figure 23.
Board Status
The two top LEDs indicate "up" status of the board. During routing module POST, the red LED on the faceplate lights and remains lit until POST is completed. After completion of POST, the green LED lights and remains solid and the red LED is extinguished.
The solid green LED indicates that the module has passed POST.
If the red LED remains lit, POST has detected a nonrecoverable error or fault. If the red LED remains lit, remove and reseat the module to run POST again.
Port Status
The four bottom bi-color LEDs, indicate port status. These bottom LEDs consist of two pairs of LEDs: the left most LED (green, red, or not lit) indicates port status and the right most LED (amber) indicates activity status, one set per port.
When the Gigabit Ethernet link is up, the left most LED will be steady green. If no light is present, the port is down. If the same leftmost LED is steady red, there is either a Remote Fault or Autonegotiation Error. A Remote Fault is usually caused by the transmit (TX) fiber of the link being broken or not connected. An Autonegotiation Error is caused by a mismatch or failure to resolve 802.3 Autonegotiation. This can be fixed by disabling Autonegotiation on both devices on the link.

Configuring Autonegotiation
The negotiation auto command enables autonegotiation on an interface.
Syntax: [no] negotiation auto
Description: By detecting the capabilities of the device at the other end of the link autonegotiation attempts to configure the highest performance mode of interoperability between the two devices.
As per IEEE 802.3 standard, autonegotiation should be configured identically on both devices of a link; if the remote device is enabled for autonegotiation, the local QSR should be enabled as well. Otherwise, one device may indicate a link is up when the other end does not.
Use the negotiation auto command to enable autonegotiation for this interface.
Use the no negotiation auto command to disable autonegotiation for this interface.
Default: Enabled.
Command Mode: Interface configuration.
Example: The following set of commands:
- Uses the configure terminal command to enter configuration mode.
- Uses the interface gbe command to enter interface mode for Gigabit Ethernet for the specified port.
- Uses the negotiation auto command to enable autonegotiation for the specified interface.
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface gbe 1/34/1
router(config-if)#negotiation auto
router(config-if)#end

Configuring ARP
Because the IP network layer is a four-byte address and the Ethernet link layer is a six-byte MAC address, a method of binding these two address types together is required to allow the transmission of data between the layers. Two types of IP to MAC address bindings or entries are supported: static and dynamic.
Static is a manual entry from the CLI using the arp command in interface mode.
Dynamic binding requires a protocol to bind addresses between the two layers. Address Resolution Protocol (ARP) is a low-level protocol that fulfills this function by dynamically binding the configured IP network layer address with the Ethernet link layer hardware address. A dynamic database of address pairings is kept in the ARP cache on each QSR module. Dynamic bindings are learned from the ARP protocol in the following three ways:
- The QSR sends out an ARP request for an IP address. The ARP reply provides the IP address requested by the QSR.
- The QSR was the target of an ARP request. In this case, the new binding is the source IP and MAC address.
- An already existing binding for this QSR is updated by an ARP request or reply that the QSR was neither the source nor the target for.
Dynamic bindings are placed in an ARP Cache and are subject to a uniform timeout or aging policy that takes into account both transmit inactivity as well as failure to periodically refresh those bindings through any one of the above three mechanisms. A timer is started when a new binding is entered for the first time in the ARP Cache, and subsequently reset whenever that binding is updated, or whenever a packet is sent to the entry's IP/MAC address. If the timer expires, the binding is removed from the ARP Cache.
In addition to deletion from inactivity or refresh failures, dynamic bindings can also be deleted manually on an individual, or per interface or module basis through the CLI at any time. Static bindings are also placed in the ARP Cache; however, they're not considered for deletion on the flush command. These bindings are also not subject to any timeouts.
Static bindings have an absolute precedence over those learned via ARP: if a dynamic mapping for a given IP address already exists when a static binding for that address is specified, the MAC address on the static binding takes precedence; furthermore, all subsequent updates coming over the wire for that IP address are discarded.
Configuring a Static Binding
The arp command is used to manually enter or delete a static binding.
Syntax: [no] arp ipaddress mac-address
ip-address
The IP address to be matched with the MAC address for the ARP cache entry.
mac-address
The Ethernet hardware MAC address to be matched with the IP address for the ARP cache entry. Valid formats are:
