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 circuit boards.

- Handle circuit boards by the faceplate or stiffener. Do not touch electrical connections, pins, or soldered surfaces.
TSR Bay Dimensions, Weights, and Floor Loading
Floor Loading
The TSR bay maximum configuration produces the following distributed and concentrated floor loading. First, the distributed load is calculated per Bellcore GR-63-CORE and NEBS requirement for the floor area of a rectangle bounded by the bay sides (without side panels) and the center line of the minimum front (1219 mm or 48 in.) and rear (609 mm or 24 in.) aisles. Second, the concentrated load is calculated for the area of the bay frame (592 mm by 638 mm or 23.3 in. by 25.1 in.). The floor loading is as follows:
Distributed Load
586 kg/m2 (120 lb/ft2)
Concentrated Load
1684 kg/m2 (345 lb/ft2)
TSR Hardware
The TSR full bay configuration design includes server modules, router modules, and other hardware components. Each router module contains a line card, a switch card, and resides in a single module enclosure. Each server module resides in a module enclosure with a power conversion card, persistent file storage, and a pair of solid state disks. The TSR Full Bay configuration is expandable to multiple bays in two back-to-back rows. Figure 1-1 shows the TSR Full Bay configuration.
Figure 1-1. Maximum Bay Configuration
TSR Full Bay Configuration
The TSR Full Bay configuration contains a collection of single IP router modules and general-purpose dual-redundant server modules interconnected through a passive fabric interconnection backplane. The backplane supports multiple switching paths that enable TSR router modules to operate independently and to intercommunicate one module to another through IP packet switching. Packet cut-through and high speed module-to-module interconnections significantly reduce packet forwarding delay. Multiple paths load share by random path selection on intermodule packet transfer. The Full Bay is currently available in 1-bay, 2-bay, and 4-bay configurations.
The TSR Full Bay is designed to incorporate fully redundant:
- Power supply inputs, at the Breaker Interface Panel (BIP) level
- Power connections, to the TSR system backplane with distributed power conversion on each module
- Cooling modules
- Server modules
Single-Bay Configuration
The TSR Full Bay hardware configuration (1-bay) consists of one fully-loaded TSR bay which includes:
- Up to two server modules
- Router modules
- Two cooling modules
- Two bay controller modules
Figure 1-2 shows the TSR bay hardware configuration.
Figure 1-2. Full Bay Hardware Configuration (1-bay)
Multi-Bay Configurations
The TSR Full Bay offers scalability without service interruptions and currently expands to offer 2-bay and 4-bay configurations. After the second bay is added to form a pair, bays are added in pairs. Please refer to the Multi-Bay Config Guide for a full explanation of any multi-bay install.
The 2-bay Configuration
In a 2-bay configuration, bays connect side-by-side. The first bay is bay 1 and the second bay is referred to as bay 3. Refer to Figure 1-3.
Figure 1-3. Full Bay Hardware Configuration (2-bay)
The 4-bay Configuration
In the 4-bay configuration, the two bay solution in the front row expands to four bays by adding bay 2 and bay 4 in a back-to-back row. Refer to Figure 1-4.

Hardware Descriptions
This section provides brief descriptions of the TSR system hardware components. The TSR system supports insertion and removal of the components with the system power on.
Bay Components
The TSR bay houses the server, router, bay controller, and cooling modules. The TSR also ships with four shelf covers. These components are all field replaceable units.
Figure 1-5 shows the TSR bay hardware components.
Figure 1-5. Bay Components
Router Modules
The TSR system supports router modules in combinations of module speeds in a single chassis backplane. Router modules support PPP, IS-IS, OSPF, BGP, and MPLS protocols.
Router modules interconnect to server modules through a 100BaseT Ethernet cable (RJ-45).
Server Modules
The TSR offers two identical servers, the primary and secondary server.
Primary Server
Each server module provides a 300 Mhz PowerPC 604e CPU, 576 Mbytes of memory (64 Mb on the baseboard and 512 Mb of add-on PMC memory), and 32Kbytes of NVRAM for maintaining configuration and software images.
The server module also supports four 10/100BaseT Ethernet port and DB-9 console port connections.
Each server module resides in a module enclosure together with a power conversion card, persistent file storage, and a pair of solid state disks.
Secondary Server (Warm Stand-by Server)
Physically identical to the primary server, the warm stand-by server is designed and implemented to take over in the event the primary server becomes inactive. The servers are connected to the bay controllers via the server connector panel. The ETH3 and ETH4 ports of the server connect to the server connector panel. A server connector panel connection leads to an Ethernet repeater located on the bay controllers. This repeater allows the bay controller and servers to look like one logical LAN. The ETH0 port provides a redundant warm stand-by connection between the servers in the event the primary warm server communication path via ETH3 and ETH4 goes down.
The primary and secondary servers contain two heartbeat connections for redundancy. ETH3 and ETH4 connections are required to form the first peering session. The first heartbeat is a multicast message over the bay controller network. The second heartbeat is over the server ETH0 port and this requires a connection to an external network management system. The two heartbeats ETH3/ETH4 and ETH0 work in unison and begin as soon as the server is activated.
If the primary server stops receiving heartbeats, it initiates a management trap, and if after 5 minutes it has not received a heartbeat, it will wait for heartbeats from the secondary server. The secondary server will wait for heartbeats from the primary server for 5 minutes before it becomes active. This allows the network operator sufficient time to reboot the primary and allow it to remain as the primary.
For software configuration details, refer to the IPriori CLI Reference (Vol. 1).
Cooling Assembly
The cooling assembly consists of two cooling modules and two bay controllers.
Each cooling module provides two fans, which are regulated by one of two bay controllers (The second controller is passive to provide redundancy if needed). The active bay controller monitors and regulates the cooling of the TSR bays by sending signals to the cooling modules to raise or lower the speed of the fans as needed.
The TSR bay controller modules monitor both the system power and cooling modules. The TSR bay controllers monitor the cooling modules and ensure proper airflow within the system components within the bay.
Bay Shelf Cover
The Terabit Switch Router bay shelf cover is an Electro-magnetic Interference (EMI) shield for EMI compliance. The TSR is shipped with the covers in place. The shelf cover fits easily onto each shelf of the TSR bay and requires no hardware.
