Antistatic Precautions
To prevent damage from static electricity follow these precautions:
- Unless you are using the appropriate antistatic protection (antistatic wrist strap or conductive mat), do not handle modules.
- When handling modules, use an antistatic wrist strap attached to the appropriate Electrostatic Discharge (ESD) ground source.
- Handle modules by the faceplate or stiffener. Do not touch electrical connections, pins, or soldered surfaces.
QSR Dimensions and Weights
Table 1-1 and Table 1-2 provide QSR and component dimensions and weights.
Rack Requirements
Mount the QSR in a standard, zone 4 seismic, 19-inch or 23-inch rack, capable of holding at least 1,000 lb. Bolt the rack to the floor according to the manufacturer's recommendations. Refer to "Rack Mounting the QSR" on page 2-10 for rack-mounting information.
QSR Configuration
The QSR architecture supports up to nine single IP router modules and a general-purpose route controller module interconnected through a passive fabric interconnection backplane.
The backplane supports multiple switching paths that enable QSR router modules to operate independently and to intercommunicate through IP packet switching. High-speed module-to-module interconnections significantly reduce packet forwarding delay. Multiple paths load share by random path selection on intermodule packet transfer.
The QSR chassis design supports fully redundant:
- Power supply inputs at the breaker switch level
- Power connections to the QSR chassis backplane with distributed power conversion on each module
- Cooling modules
- Route controller modules
- Bay controller modules
Figure 1-1 shows the QSR chassis hardware.
Figure 1-1. QSR Chassis

The QSR is currently available in single- or multiple-chassis configurations.
Single-Chassis Configuration
As shipped, a minimum single-chassis QSR configuration includes:
- The QSR chassis
- One Electro Magnetic Interference (EMI) Cover
- One route controller module
- Two router modules
- Two fabric filler modules
- Five standard filler modules
- Two bay controller modules
- Two cooling modules
- One cable-management tray
- One air filter
Multiple-Chassis Configuration
The QSR offers scalability without service interruption and expands to offer multiple-chassis solutions, including a QSR-to-QSR solution. Connectors on the back of the chassis allow for multiple-chassis configurations.
In multiple-chassis configurations, a second QSR can house up to ten router modules. At least one of the connected QSRs must contain a route controller module.
For information about installing and connecting multiple-chassis configurations, refer to "Rack Mounting the QSR" on page 2-10.
Hardware Description
This section describes QSR hardware components. The QSR supports the insertion and removal of the modules with the chassis powered on. The QSR ships with an EMI cover installed. For ease of viewing, the EMI cover is not shown in Figure 1-2.The QSR ships with two (2) sets of mounting ears.
Front of Chassis
The QSR houses route controller, router, bay controller, and cooling modules, as well as an air filter. All are field replaceable units.
Figure 1-2 shows installed QSR hardware components. Component descriptions follow the figure.
Figure 1-2. QSR Features - Front

Cooling Modules
Each cooling module contains three fans, which are regulated by one of the two bay controller modules. The active bay controller module monitors and regulates the cooling of the QSR by sending signals to the cooling modules to raise or lower the speed of the fans as needed.
The QSR ships with two cooling modules installed.
Route Controller Modules
The QSR supports up to two route controller modules, a primary (active) and secondary (passive) route controller module. The QSR accepts only Non-Stop Routing (NSR®TM) Route Controller Modules.
NOTE Route controller modules are also known as server modules. Both serve the same purpose.
Each route controller module provides an 867-Mhz MPC7455 Power PC and 2 GB of SDRAM.
The route controller module also supports seven 10/100BaseT Ethernet ports, one local fast Ethernet port (not user accessible), and one DB-9 console port connection. Two Type 1/Type 2 PCMCIA slots house the two industrial grade Flash Memory cards provided with the system (not user accessible).
For more information, see the documentation that ships with the controller.
Primary and Secondary Controllers
The primary and secondary route controller modules are physically identical. The secondary (or passive) controller takes over if the primary controller becomes unusable.
Route controller modules connect to the bay controller modules via the route controller module panel. For maximum system redundancy and increased fault tolerance over two connected QSRs, install the second route controller in slot S10 of the second chassis.
Route controller modules connect to the bay controller module faceplate. These connections lead to an Ethernet repeater located on the bay controller modules. The repeater allows the bay controller module and route controller modules to look like one logical LAN.
For route controller module software configuration details, refer to the IPriori CLI Reference and Configuration Guides (Vol. 1).
The route controller module configured with the lowest ID number is the active or primary route controller module.
Fabric Filler Module
Fabric filler modules ensure a robust and reliable topology by creating a physical bridge for more than one active link between modules. This is especially important when two router modules are installed in a QSR that is not fully populated. Install fabric filler modules like book ends on either side of a block of installed router modules. (Details about population rules are located in "QSR Module Population Rules" on page 3-8.)
Router Modules
The QSR chassis supports router modules in combinations of speeds in a single chassis backplane. The QSR supports routers using the following protocols:
PPP IS-IS OSPF BGP MPLS
POS GE PIM-SM Gigabit ethernet
Cable Management Tray
The QSR cable management tray helps you keep cables out of the way to prevent accidental jarring or disconnection.
Air Filter
The QSR air filter keeps debris and dust from interfering with system operation. To optimize QSR performance, check and clean the air filter as prescribed in "Cleaning and Replacing the Air Filter" on page B-2.
Breaker Switches
QSR breaker switches let you control power to the modules.
Mounting Ears
Integrated mounting ears let you front, mid, or rear mount the QSR in a standard rack. Two sets of mounting ears ship (front and middle) on the QSR chassis.
The front and middle mounting ears are removable. The QSR ships with the front and middle mounting ears installed. Mounting ears on the middle of the chassis may be moved to allow rear mounting. For details about rack mounting, see "Rack Mounting the QSR" on page 2-10.
Bay Controller Modules
QSR bay controller modules operate under the direction of a server to monitor the system power and cooling modules. Two bay controller modules in the QSR offer redundant control to maintain QSR operation.
The bay controller module
- Monitors and controls the cooling modules
- Monitors the -48 Vdc shelf power supplies
- Provides a low-speed communication channel to/from each installed module for module bring-up
- Provides an interface to the server
- Controls LED alarm indicators
- Provides control circuits for central office visual and audible alarm indicators
The QSR ships with two bay controller modules already installed.
Back of Chassis
From the back of the system chassis, you can access the Y-connector boards, power terminal strip, bay controller backplane, and ground plate.
Figure 1-3 shows the location of these features, which are described after the figure. (To show the Y-connector boards and backplane features, the rear covers in the following figure are removed.)

Y-Connector Boards
The Y-connector boards on the back of the QSR provide Y-link communication between the modules installed in the chassis.
Ground Plate
The ground plate provides a place to properly earth ground the QSR. See "Installing Safety Ground to the QSR" on page 3-3 for details on doing so.
Power Terminal Strip
The power terminal strip provides the location for connecting the QSR to the customer power source. See "Installing Power and Return Feeds" on page 3-5 for more information.
Bay Controller Backplane
The bay controller backplane provides ports for interconnecting multiple chassis and a rotary dial for chassis identification. Even if your facility has only a single QSR, verify the rotary dial setting. Figure 1-4 shows backplane features.
