Route Controller Module
The route controller module supports Non-Stop Routing (NSR®), a routing functionality ensuring immediate redundancy in case of a route controller failure. A system must have at least two route controllers for NSR® support.
The QSR route controller module has seven (7) 10/100BaseT Ethernet ports, a console port (DB9), a lamp test button, and LEDs indicating the status of the Non-Stop Routing configuration (see Figure 1).
Figure 1. Route Controller Faceplate
Pressing the lamp test button tests the operational status of all the LEDs on the route controller. LEDs on each of the seven Ethernet ports indicate the state and activity of each of the ports. Each route controller resides in a module enclosure together with a power conversion card and persistent file storage.
LEDs on each of the seven Ethernet port indicates the state and activity of each of the ports (see Table 1 "Ethernet Port LEDs").
Table 1. Ethernet Port LEDs Link Activity Green solid - linked

Depending on the configuration, a route controller can operate as a Primary, Backup, or Redundant route controller. A Primary route controller is the active route controller. A Backup route controller is a route controller standing by to replace the Primary in case of failure. For a route controller to be Redundant, it must be either the third or fourth route controller within a system. In addition, the NSR® Ready LED lights when the Backup or Redundant route controller is capable of taking over the functions of the Primary in a hitless fashion.
NOTE The route controller module can be visually identified by a red dot located on the top of the module.
The four NSR® status LEDs indicates the state and activity of each of the route controllers (see Table 2 "Non-Stop Routing LED Indicators").
Non-Stop Routing
Non-Stop Routing is a routing functionality ensuring immediate redundancy in case of route controller failure. NSR® functionality requires two or more route controllers configured for NSR® within one system.
The three modes of redundancy are: NSR® protection, warm protection, and no redundancy.
- NSR® protection requires at least two route controllers (primary and backup) in a system and provides hitless routing protocol fail-over and hitless software upgrades.
- Warm Protection provides a non-hitless backup route controller to the primary controller. The warm route controller continuously monitors the primary controller. If the primary fails, the warm route controller assumes the primary role and resets the system.
- No redundancy is available when only one route controller populates a system.
For route controller software configuration details, refer to the IPriori Software Configuration Guide (Vol. 3). When configuring the route controllers, keep in mind that the route controller configured with the highest primary-preference value will be the active or primary route controller. If all primary preferences values are the same, the lowest Server-ID will become the Primary.
Preparing to Install Route Controller Modules
When installing the route controller module, be sure to follow all antistatic precautions. In order to prevent damage to the QSR system from static electricity, observe the following:
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.
Handle modules by the faceplate and outer enclosure only. Do not touch electrical connections, pins, or soldered surfaces.
CAUTION (1) Risk of service interruption or equipment damage. Risk of electrostatic damage. When handling modules, wear a grounded antistatic wrist strap or equivalent protection to avoid damaging electrostatic parts.
Installing the Wrist Strap
A grounded antistatic wrist strap must be used to protect the SSR chassis modules and components from damage caused by static.
PROCEDURE: Use the following procedure to install the antistatic wrist strap:
Step 1 Remove the alligator clip from the grounding pin on the antistatic wrist strap.
Step 2 Insert the grounding pin into the electrostatic discharge (ESD) jack on the front of the QSR chassis shelf (refer to Figure 2).
Step 3 Use the ESD jack while handling modules.
Figure 2. ESD Jack Locations (Front)
CAUTION (2) Risk of electrostatic damage. You must wear antistatic wrist strap or equivalent protection to avoid damaging electronics parts.
QSR Module Population Rules
Each QSR chassis has one shelf with ten (10) slots to house route controller and router modules. Route controller modules must be installed in slots 10 (Primary) and 1 (Secondary).
NOTE Route controller a.k.a. servers appear are identified as servers in the CLI command line. In addition, modules acting as SAMs appear in the CLI command line as SAMs.
QSR Chassis Slot Numbering
Figure 3 shows QSR chassis slot numbering when viewed from the front of the QSR.
Figure 3. QSR Chassis Slot Numbering
Populating Rules for Route Controller Modules
The rules for populating the first QSR chassis with route controller modules is as follows:
- The server modules are restricted to slots 10 and 1 (see Figure 3).
- When installing only one server, it must be in slot 10.
Removing the Route Controller Modules
If you need to remove a route controller module from the chassis, begin with this procedure. If removing a fabric filler or filler module, proceed to "Removing Fabric Filler Modules" or "Removing Filler Modules" .
CAUTION (3) Within five minutes of removal of a module, a replacement module or a fabric filler module must be installed in the empty slot.
PROCEDURE: Use the following steps to remove the route controller module(s) after putting on a grounded antistatic wrist strap:
Step 1 Verify that your antistatic wrist strap is properly grounded.
Step 2 Using a screwdriver, disconnect the console connector from the console port (see Figure 4).

Figure 9. Closing of Ejector Latches
Step 9 To remove the module, grasp it on the top and bottom and pull it carefully out of the shelf.
Step 10 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 and two (2) fabric filler modules which ensure proper cooling and elimination of electromagnetic interference during operation. Remove filler modules or fabric filler modules from slots intended for route controller modules.
Removing Fabric Filler Modules
If the slot intended for the route controller contains a fabric filler module, remove it using the procedure below.
CAUTION (6) 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.

Step 2 Pull the filler module out of the slot (see Figure 13).
Step 3 Store the filler module in a dry, cool area.
Figure 13. Removing Filler Modules
Installing the Route Controller Module
Install the route controller module after removing either a router, filler, or fabric filler module. Refer to "Populating Rules for Route Controller Modules" .
CAUTION (8) Risk of electrostatic damage. You must wear a grounded antistatic wrist strap or equivalent protection to avoid damaging electronics parts.
Step 1 Use the following procedure to install the route controller module in a QSR:
Step 2 Verify that the wrist strap you are wearing is properly grounded or that other antistatic measures are in place.
Step 3 Remove the route controller module from its static protection package.
Step 4 Ensure that all bay cabling is clear for module insertion.
Step 5 Check that the ejector latch release levers are in the closed position. If they are open, close them (see Figure 14).
NOTE When the ejector latch release lever is in the open position, do not use the lever to lift or adjust the module in the card guide (see Figure 14).
Figure 14. Route Controller Ejector Release Levers
Step 6 Prior to insertion, a detailed inspection of the power connector on the route controller module must be performed. Lay the module on a flat surface so you can inspect the power connector.
Step 7 Carefully inspect the power connector for damage. There should be no gap between the bracket and board on the power connector (see Figure 15). If no damage exists, proceed with installation.
Figure 15. Route Controller Module Power Connector
NOTE If the power connector has any signs of damage, DO NOT insert it into the bay. Mark the module as damaged and call TSR-BY-AVICI to request an RMA.
Step 8 Align the module with the card guides of the slot and slide the route controller module into the slot until the ejector latch's release lever tab hits the outer lip of the shelf (see Figure 14 and Figure 16).

Installing the Cable Management Bracket
Installation of the cable management bracket simplifies cable management of the route controller module. Receptive screw holes in the module faceplate accept the captive screws of the cable management bracket. Velcro fasteners in the cable management bracket allow easy dressing and organization of fiber optic cables.
CAUTION (9) The cable management bracket is for cable management purposes only. The cable management bracket must be removed prior to removing the route controller module. DO NOT use the cable management bracket to lift or carry the route controller module. Failure to adhere to these guidelines may result in equipment damage.
Figure 21. Cable Management Bracket Installation
PROCEDURE: Use the following procedure to install the cable management bracket to the module:
Step 1 Remove the cable management bracket from its package.
Step 2 Position the cable management bracket as shown in Figure 21.
Step 3 Using a 3/8 in flat-head screwdriver, attach the bracket to the module faceplate by tightening the captive screws (see Figure 21).
Installing Route Controller Module Cables
Each route controller module supports seven Ethernet ports (ETH 0-6) and one female console (DB-9) port. The Ethernet ports provide for interconnection to the Server-Attached Modules (SAMs) within the bay and to the network management system via the bay controllers through the server connection panel. The console port provides connection to a console terminal for access to CLI configuration.
Redundant Bay Controllers
The QSR offers route controller to bay controller fault tolerance via a connection from both the primary and secondary route controller's ETH 3 and ETH 4 ports to the bay controller network on the route controller connector panel. The primary route controller's ETH3 and ETH4 ports connect to the bay controller network via the route controller connector panel (see Figure 22).
Figure 22. Bay Controller Connection Ports
IPriori determines whether a route controller is primary or secondary based upon route controller ID not the route controller slot location. The primary route controller is the lower of the two server IDs.
The recommended cabling to maintain bay controller to route controller redundancy is to cable the Ethernet Ports 3 (ETH 3) to one bay controller and 4 (ETH4) to the second bay controller. Bay controllers are identified on the server connection panel (see Figure 22). This minimizes shared components in each path.
Table 3 specifies the recommended port connections for each route controller.

Cabling the Primary Route Controller
Each route controller module attaches to two router modules, also called Server-Attached Modules (SAMs). Any router module can serve as a SAM. The dual SAM system provides system redundancy.
CAUTION (10) All cables used to cable the route controller module must be shielded.
Cables connecting the route controller module to the connection panel on the bay are Micro D DB-9 at one end and RJ-45 connectors at the other. Cables connecting the route controller to SAM modules may either be Micro D DB-9 to Micro D DB-9 (Family 2 - newer module faceplate) or Micro D DB-9 to RJ-45 (Family 1 - former module faceplate). Procedure include how to cable both faceplates.
NOTE You may choose any two modules per route controller to act as your SAM modules. For maximum fault tolerance, we recommend that the primary and backup SAM module be on different shelves.
Route controller module cable kits ship with bays and chassis. The QSR cable kit includes the following:
NOTE All DB-9 connectors and cables must be standard.
PROCEDURE: Use the following steps to cable the primary route controller module. Refer to Figure 23 for an illustration of the cable connector types and Ethernet port designations
Figure 23. Route Controller Module Cable Connections
Step 1 Primary CONSOLE - Attach a DB-9 RJ-45 adapter from this connector on the primary route controller module to one end of the UTP cable with RJ-45 connectors on each end. Take the RJ-45 connector on the other end of the UTP cable and plug it into the female adapter, which can plug into a console terminal (PC) port, or connection of your choice.
Step 2 Primary ETH 0 - Attach an RJ-45 Ethernet cable from this connector on the primary route controller module to the remote network management system within the central office.
Step 3 Primary ETH 1 - Attach a standard Micro-D Ethernet cable from this connector on the primary route controller module to the DB-9 Ethernet port on the SAM module. This router module is the primary SAM (see Figure 24).
NOTE All DB-9 connectors and cables must be standard.
Figure 24. Ethernet Attachment to SAM
NOTE Primary ETH 1 - Attach a standard Micro D DB-9 Ethernet cable from this connector on the primary route controller module to the RJ-45 connector located in the AUX tray of the router module. (Slide out the cable tray labeled AUX to make this connection.) This router module is the primary SAM. (See Figure 25.)
Figure 25. Ethernet Attachment to SAM
Step 4 Primary ETH 2 - Attach a standard Micro D DB-9 Ethernet cable from this connector on the primary route controller module to the DB-9 Ethernet port on the SAM module. This router module is the secondary SAM (see Figure 24).
NOTE Primary ETH 2 - Attach a standard Micro D DB-9 Ethernet cable from this connector on the route controller module to the RJ-45 connector located in the AUX tray of the router module. (Slide out the cable tray labeled AUX to make this connection.) This router module is the primary SAM. (See Figure 25.)
Step 5 Primary ETH 3 - Attach a standard Micro D DB-9 Ethernet cable from the route controller module to a port on Bay Controller 1 (see Figure 26).

Figure 27. Micro D Ethernet Attachment to Bay Controller Port
Cabling the Secondary Route Controller
Use the following steps to cable the secondary route controller module. Refer to Figure 28 for an illustration of the cable connector types and Ethernet port designations.
CAUTION (11) All cables used to cable the route controller module must be shielded.
Figure 28. Route Controller Module Cable Connections
Step 1 Secondary ETH 0 - Optionally attach an RJ-45 Ethernet cable from this connector on the secondary route controller module (S2) to the remote network management system within the central office. This connection will have no affect upon network management unless the secondary becomes the primary. It does provide a redundant communication between route controllers should both the ETH3 and ETH4 connections go down.
Step 2 Secondary ETH 1 - Attach a standard DB-9 Ethernet cable from this connector on the primary route controller module to the DB-9 Ethernet port on the SAM module. This router module will become the primary SAM should the secondary route controller become primary (see Figure 29).
Figure 29. Ethernet Attachment to SAM
NOTE Secondary ETH 1 - Attach a standard Micro D DB-9 Ethernet cable from this connector on the primary route controller module to the RJ-45 connector located in the AUX tray of the router module. (Slide out the cable tray labeled AUX to make this connection.) This router module is the secondary SAM. (See Figure 30.)
Figure 30. Ethernet Cable Connection
Step 3 Secondary ETH 2 - Attach a standard Micro D DB-9 Ethernet cable from this connector on the primary route controller module to the DB-9 Ethernet port on the SAM module. This router module is the secondary SAM (see Figure 29).
NOTE Secondary ETH 2 - Attach a standard Micro D DB-9 Ethernet cable from this connector on the primary route controller module to the RJ-45 connector located in the AUX tray of the router module. (Slide out the cable tray labeled AUX to make this connection.) This router module is the primary SAM. (See Figure 30.)
Step 4 Secondary ETH 3 - Attach a standard Micro D DB-9 Ethernet cable from the route controller module to a port on Bay Controller 1 (see Figure 31).
Figure 31. Micro D Ethernet Attachment to Bay Controller Port
Step 5 Secondary ETH 4 - Attach a standard Micro D DB-9 Ethernet cable from the route controller module to a port on Bay Controller 2 (see Figure 32).
Step 6 Proceed with configuration as outlined in the Ipriori Configuration Guide (Vol. 1).
