T320 Internet Router and T640 Internet Routing Node Control Board (T-CB ) Installation Instructions

T-CB Description

Each T-CB works with an adjacent Routing Engine to provide control

and monitoring functions for the routing platform (see Figure 1). These

functions include determining Routing Engine mastership; controlling power

and reset for the other routing platform components; monitoring and

controlling fan speed; and monitoring system status.

You can install one or two T-CBs in the routing platform. The T-CBs install

into the upper rear of the chassis in the slots labeled

CB0 and CB1 (referred

to as

T-CB-0 and T-CB-1). If two T-CBs are installed, one functions as the

master T-CB and the other as its backup. If the master fails or is removed,

the backup restarts and becomes the master.

if a Routing Engine is not present in the adjacent slot.

T-CBs are hot-pluggable.

2 T-CB Description

T-CB Components

Each T-CB consists of the following components:

100-MB Ethernet switch. This switch is used for intermodule communication.

PCI bus to the Routing Engines.

Processor subsy stem (SPMB).

Three LEDs, located on the T-CB faceplate. These indicate the status of the

T-CB. Table 1 describes the functions of the T-CB LEDs.

Online/offline b utton, located on the T-CB faceplate. This button is

nonfunctional.

Two configuration switches, located on the T-CB faceplate.

NOTE: The M/S and CHASSIS ID switches on the T-CB faceplate must always be set to

S and 0 in a standalone routing platform.

If a T640 routing node is connected to a TX Matrix platform, these switches must

be set to

M and the chassis identifier (ID) of the routing node. In this case, both

T-CBs must have t he same chassis ID. For more information, see the TX Matrix

Platform Hardware Guide.

Two RJ-45 ports labeled AUX and CIP on the T-CB faceplate. These ports are not

used in a standalone routing platform. Only the

CIP port is used in a T640

routing node connected to a TX Matrix platform. For more information, see

the TX Matrix Platform Hardware Guide.

T320 Internet Router and T640 Internet Routing Node Control Board (T-CB ) Installation Instructions

Tools and Parts R equired

To replace a T-CB, you need the following tools:

Phillips (+) screwdriver, number 2

ESD wrist strap with cable

Electrostatic bag or antistatic mat

Blank panels to cover any slots not occupied by a component

Replacing a T-CB

The T-CBs are hot-pluggable. If the routing platform contains a redundant host

subsystem, the T-CB an d the Routing Engine are hot-removable and hot-insertable.

Before you replace a T-CB or a Routing Engine, you must take the host subsystem

offline(seetheT320 Internet Router Hardware Guide or the T640 Internet Routing

Node Hardware Guide). To replace a T-CB, use the following procedures:

NOTE: The figures in these procedures show the T640 routing node for reference.

Removing a T-CB

The routing platform can have one or two T-CBs. They are located in

the upper rear of the chassis in the slots marked

CB0 and CB1.Each

T-CB weighs approximately 5 lb (2.3 kg).

To remove a T-CB, follow this procedure (see Figure 2):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.

2. At tach an electrostatic discharge (ESD) grounding strap to your bare wrist

and connect the strap to one of the ESD points on the chassis. For more

information about ESD, see the T320 Internet Router Hardware Guide or the

T640 Internet Routing Node Hardware Guide.

3. Check whether the T-CB is functioning as the backup or as the master. If

necessary, take the host subsystem offline as described in the T320 Internet

Router Hardware Guide or the T640 Internet Routing Node Hardware Guide.

4. If applicable, disconnect the cable plugged into the port labeled CIP.

5. Loosen t he captive screws (using a Phillips (+) screwdriver, number 2) on the

ejector handles on both sides of the T-CB faceplate.

6. Flip the ejector handles outward to unseat the T-CB.

7. Grasp the ejector handles and slide the T-CB about halfway out of the chassis.

8. Place one hand underneath the T-CB to support it and slide it completely

outofthechassis.

9. PlacetheT-CBontheantistaticmat.

10. If you are not replacing the T-CB now, install a blank panel over the empty slot.

Installing a T-CB

To install a T-CB, follow this procedure (see Figure 3):

1. At tach an electrostatic discharge (ESD) grounding strap to your bare wrist

and connect the strap to an approved site ESD grounding point. For more

information about ESD, see the T320 Internet Router Hardware Guide or the

T640 Internet Routing Node Hardware Guide.

2. Ensure the ejector handles are not flush with the faceplate. If necessary, loosen

the captive screws and flip the ejector handles outward.

3. Carefully align the sides of the T-CB with the guides inside the chassis.

4. Slide the T-CB into the chassis, carefully ensuring that it is correctly aligned.

5. Grasp both ejector handles and press them inward to seat the T-CB.

6. Tighten the captive screws on the ejector handles, using a Phillips (+)

screwdriver, number 2.

7. If applicable, reconnect the cable previously plugged into the CIP port.

8. If power is applied to the T-CB and its corresponding Routing Engine is

functioning normally, the T-CB comes online automatically. To verify that the

T-CB is functioning normally, check the LEDs on its faceplate. The green

OK LED

should light steadily a few minutes after the T-CB is installed. If the

FAIL LED is

lit steadily, remove and install the T-CB again (see “Removing a T-CB” on page

4 and “Installing a T-CB ” on p age 5 ). If the

FAIL LED still lights steadily, the

T-CB is not functioning properly. Cont act your cust omer support representativ e.

To check the status of the T-CB, use the CLI command:
