Installing the Processor Card in the Chassis

This section describes how to install the processor card in the Catalyst 8540 MSR, Catalyst 8510 MSR, Catalyst 5500 switch, and LightStream 1010 ATM switch chassis. The process to install the processor card in the four chassis is essentially the same.

The Catalyst 8540 MSR is a 13-slot modular chassis. Slots 4 and 8 are reserved for the processor card. Slots 0 through 3 and 9 through 12 can contain up to eight full width interface modules or 16 half width port adapters. Slots 5 and 7 are reserved for the switch modules. Slot 6 remains empty. (See Figure 2-1.)

Figure 2-1: Slot Numbers for the Catalyst 8540 MSR Chassis

The Catalyst 8510 MSR and the LightStream 1010 ATM switch are five-slot modular chassis. Slot 2 is reserved for the processor card. The other four slots are used for carrier modules and port adapters. (See Figure 2-2.)

Note You can also install the processor card as an option in the Catalyst 5500 switch.
Slot 13 is reserved for the processor card in the Catalyst 5500 switch. Slots 9 through 12 are used for carrier modules and port adapters. Refer to the Catalyst 5500 switch documentation for more information.

To install the processor card, follow these steps:

Step 1 Turn off the system; but, to channel ESD voltages to ground, do not disconnect the power cable.

Caution Turn off the system before removing the processor card. Removing the processor card from the system while it operates shuts down ATM switching. However, the processor card is hot swappable in all chassis; that is, no hardware damage occurs if it is removed while the power is on.

Step 2 Hold the processor card faceplate with one hand, and place your other hand under the carrier. Avoid touching the components on top of the card to prevent ESD damage.

Step 3 Align the processor card with the rails on the inside of the chassis.
(See Figure 2-3.)

Step 4 Carefully slide the processor card into slot 4 of the Catalyst 8540 MSR (or slot 2 of the Catalyst 8510 MSR and LightStream 1010, or slot 13 of the Catalyst 5500 switch) until the processor card stops and the release levers are protruding outward.

To check the installation, enter the show hardware privileged EXEC command to verify that the system has acknowledged and brought up the new interfaces.

Redundancy

The Catalyst 8540 MSR chassis supports fault tolerance by allowing a secondary route processor to take over if the primary processor card fails. This secondary, or redundant, processor card runs in standby mode. In standby mode, the secondary processor card is partially booted with the Cisco IOS software; however, no configuration is loaded.

To install a secondary processor card in the Catalyst 8540 MSR chassis, follow these steps:

Step 3 Carefully slide the processor card into slot 8 until the processor card stops and the release levers are protruding outward. (See Figure 2-4.)

Connecting the Processor Card to a Network

This section describes how to connect the processor card to a network.

• The type of cable required for each interface:

  • Straight-through Ethernet for the RJ-45 Ethernet port

  • Null-modem EIA/TIA-232 for the auxiliary port

  • Straight-through EIA/TIA-232 for the console port

• The distance limitations for each signal type

• Any additional interface equipment you need, such as transceivers, modems, channel service units (CSUs), or data service units (DSUs)

---

Note Before installing the system, have all additional external equipment and cables on hand. For ordering information, contact a customer service representative. To build your own cables, see the cable pinouts in "Processor Card Cable and Port Pinouts."

---

Managing Your Port Connections

You need a straight-through Ethernet cable with RJ-45 male connectors (see Figure 2-5) for connection between the Ethernet port and an Ethernet network. Table B-1 lists the Ethernet cable connector pinouts.

The auxiliary port on the processor card is a male, EIA/TIA-232, DTE, DB-25 plug. You can attach a CSU/DSU or other device to access the system from the network. The asynchronous auxiliary port supports hardware flow control and modem control. The auxiliary port requires a null-modem EIA/TIA-232 cable. Table B-2 lists the signals used on this port.

The console port on the processor card is a female, EIA/TIA-232, DCE, DB-25 receptacle. Both data set ready (DSR) and data carrier detect (DCD) activate when the system is running. The Ready to Send (RTS) signal tracks the state of the Clear to Send (CTS) input. The console port does not support modem control or hardware flow control. The console port requires a straight-through EIA/TIA-232 cable. Table B-3 lists the signals used on this port.

Before connecting to the console port, determine the baud rate of your terminal, which must match the default baud rate (9600 baud) of the port you use. Set up the terminal as follows:

• 9600 baud

• 8 data bits

• No parity

• 1 stop bit

Auxiliary and Console Port Connection Equipment

The processor card includes one EIA/TIA-232, data terminal equipment (DTE) auxiliary port and one EIA/TIA-232, data communications equipment (DCE) console port (see Figure 2-6). These ports provide access to the system either remotely (with a CSU/DSU or other DTE device) or locally (with a console terminal). This section describes important cabling information to consider before connecting a CSU/DSU to the auxiliary port or a console terminal (an ASCII terminal or PC running terminal emulation software) to the console port.

The auxiliary and console ports differ in that the auxiliary port supports hardware flow control and modem control, and the console port does not. Flow control paces the transmission of data between a sending device and a receiving device. Flow control ensures that the receiving device can absorb the data sent to it before the sending device sends more. When the buffers on the receiving device are full, the sending device receives a message to suspend transmission until the data in the buffers are processed. Because the auxiliary port supports flow control, it is ideally suited for use with the high-speed transmissions of a modem. Console terminals transmit at slower speeds than modems; therefore, the console port is ideally suited for use with console terminals.

EIA/TIA-232 supports unbalanced circuits at signal speeds up to 64 kbps. Figure 2-7 shows the connectors at the network end of the adapter cable for DCE and
DTE connections.

Installing and Removing Flash PC Cards

This section describes how to install and remove Flash PC Cards. Flash PC Cards ship either installed in the system or as a spare part. When the Flash PC Card is shipped installed, the card contains a system image. When the card is shipped as a spare part, it is unformatted; you must format the card before you use it.

Step 1 Face the front panel of the processor card (see Figure 2-8) and hold the Flash PC Card with the connector end of the card toward the slot. The label on the Flash PC Card should face up (see Figure 2-8a).

Step 2 Insert the card into the appropriate slot until the card is completely seated in the connector at the back of the slot and the eject button pops out toward you (see Figure 2-8b). Note that the card does not insert all the way inside the processor card; a portion of the card remains outside of the slot. Do not attempt to force the card past this point.

---

Note The Flash PC Card is keyed and cannot be seated the wrong way. The eject button does not pop out until the card is inserted properly.

---

Step 3 To eject the card, press the eject button corresponding to the slot until the card is free of the connector at the back of the slot. (See Figure 2-8c.)

Step 4 Remove the card from the slot and place it in an antistatic bag to protect it from ESD damage.

Installation and removal of the Flash PC Card is now complete.

Processor Card LEDs

This section describes the LEDs used to confirm and troubleshoot operation of the processor card. The LEDs on the processor card indicate the status of the processor card, the fan assembly, and the power supplies. The Catalyst 8540 MSR processor card LEDs are shown in Figure 2-9 and described in Table 2-1. The LEDs on the Catalyst 8510 MSR, Catalyst 5500 switch, and LightStream 1010 switch processor card are shown in Figure 2-10 and described in Table 2-2.

Confirming the Processor Card Installation

Problems with the initial startup are often caused by an interface processor card or power supply that has become dislodged from the backplane or chassis power connector during shipment. Although over-temperature conditions rarely occur at initial startup, the environmental monitoring functions are included because they also monitor DC line voltages. At the initial system boot, verify the following:

• The power supplies are installed properly and are supplying power to the system.

• The system fan assembly is operating.

• The system software boots successfully.

• The processor card and all carrier modules and port adapters are properly installed in their slots and each is initialized without problems.

Diagnostics

The power-up or hardware reset diagnostics provide full sets of test suites to test the system hardware. The test results are stored in the system memory and an interface is provided using the show diag power-on command. If an error is detected during the test, the processor card status LED turns red.

Troubleshooting Flowchart

The flowchart in Figure 2-11 helps you determine which component of your system might have malfunctioned.
