Antistatic Precautions
This section describes the procedure to prevent damage to the QSR system from static electricity.
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.
Figure 1. QSR ESD Jack Location (Front)
CAUTION (1) When handling router modules, wear a grounded wrist strap or equivalent antistatic protection to prevent damage to electronic parts.
Optical Characteristics
The 4-Port OC-12c and the 2-Port OC-48c modules support Telcordia Single Mode Short Reach SR-1 compliant optics as described in GR-1377-CORE, compatible with SR-1 and GR-253 and I-64.1 of ITU G.691. Refer to Table 1 and Table 2.
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.
The software command show population designates router module population sequence. Use this command to determine where to install the router module in the chassis.
Figure 2. QSR Chassis Slot Numbering
Rules for populating a single QSR chassis are as follows:
- Install route controller modules in slots S10 and S1. The QSR accepts only NSR® Route Controller Modules.
- When only one route controller module is installed, it must be installed in S10. Use slot 1 for a router or a filler module.
- Initial installation of two router modules is required in the first QSR chassis only.
- A module occupying a slot uses the slot number as its identifier.
- Every router module must be abutted by another router module, a route controller module, or a fabric filler module.
NOTE Remember, if installing modules in slots 5 and 6 only, slots 4 and 7 must contain a fabric filler module. The remaining empty slots must contain standard filler modules.
- 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.
- The QSR accepts only red modules.
- If installing the module in a cold chassis, follow the Population Rules outlined in the Quarter-rack Scalable Router Install Guide.This router 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.
PROCEDURE: Use the following steps to remove the router module(s):
Step 1 Verify that the wrist strap you are wearing is properly grounded or that other antistatic measures are in place.
Step 2 Open the pull tab on the center cable tray and gently pull the center cable tray out of the router (see Figure 3 and Step 4).
Figure 3. Router Module Faceplate
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.
Step 3 Disconnect the lower fiber optic cables from the fiber cable adapters (SC) on the center 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 center cable tray back into the router module and close the cable tray pull tab. If necessary, repeat Step 2 through Step 3 for fiber optic cable connections in the right cable tray.
- If the module is a SAM, proceed to Step 5, if not then 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).
Step 8 Hang the Ethernet cable down and out of the way, or tuck the cable into the horizontal cable tray under the module shelf.
Step 9 Gently push all cable trays to the closed position and close the cable tray pull tabs.
Step 10 To unlock the ejector latches, simultaneously slide the release levers in the direction of the arrows (see Figure 6).
Figure 6. Router Module Removal
Step 11 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).
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 12 Hold 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 13 To remove the module, grasp it on the top and bottom and pull it carefully out of the shelf.
CAUTION (5) A detailed inspection of the Very High Density Metric (VDHM) connector is required each time a module is removed or inserted. Lay the module gently on its side to perform a VHDM connector inspection.
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 7).
Figure 7. Cable Tray Pull Tab
CAUTION (6) Any contact to a VHDM connector outside a QSR could damage the connector.
Step 14 Carefully inspect the VHDM connector for damage such as deformed sockets, holes between socket columns, and deformed guide fins on top and bottom of the socket columns.
Figure 8. VHDM Connector
.
CAUTION (7) If the VHDM connector has any signs of damage, DO NOT insert it into an TSR II. Mark the module and slot as damaged and call TSR-BY-AVICI to request an Return Material Authorization (RMA).
DO NOT insert a new router module into the slot. If the slot is damaged, only insert filler modules. Contact Support Service immediately.Step 15 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 13). If this is an RMA, repackage according to RMA directions. Ship back to Avici.
Step 16 If the slot is not populated with a module, it must be filled with a filler or fabric 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 VDHM 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 10):
- Press release levers in the directions indicated by the arrows on the latch.
- Rotate the ejector latches away from the module faceplate.
