Safety Recommendations

Follow these recommendations when installing the processor card to ensure your safety and to protect the equipment:

• Clear the chassis area and keep it dust-free during and after installation.

• Store tools and chassis components away from walk ways.

• Fasten your tie or scarf and roll up your sleeves. Never wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the chassis.

• 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.

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground causing serious burns or welding the metal object to the terminals.

Warning Ultimate disposal of this product should be handled according to all national laws and regulations.

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

Safety with Electricity

The processor card, carrier modules, port adapters, and redundant (second) power supplies are designed to be removed and replaced while the system is operating (hot swapped) without presenting an electrical hazard or damaging the system. Before removing a redundant power supply, ensure that the first supply is turned on (|) and the power supply being removed is turned off (0).

• Locate the emergency power switch for the room in which you will be working before accessing the chassis interior.

• Examine your work area carefully for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

• Disconnect all power and external cables before installing or removing a chassis.

• Work under supervision when potentially hazardous conditions exist.

• Check, never assume, that power has been disconnected from a circuit.

• Use caution when working with the equipment. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.

In addition, use the following guidelines when working with any equipment disconnected from a power source but still connected to telephone wiring or other network cabling:

• Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

• Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

• Always use caution when installing or modifying telephone lines.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The processor card consists of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use a preventive antistatic strap whenever you handle the processor card. Handle the metal carrier by the edges only; never touch the printed circuit card or connector pins.

Follow these guidelines to prevent ESD damage:

• Place a removed processor card component side up on an antistatic surface or in a static shielding bag. If you are returning a processor card to the factory, immediately place it in a static shielding bag.

• Use an ESD-preventive wrist or ankle strap. Make sure that the strap directly contacts the skin.

• Avoid contact between the processor card and your clothing. The ESD-preventive strap protects only the card from ESD voltages on the body; ESD voltages on clothing can still cause damage.

• Connect the equipment end of your ESD-preventive strap to one of the captive installation screws on an installed card or power supply. (See Figure 2-1.)

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms (Mohms).

Warning During this procedure, wear grounding wrist straps to avoid ESD damage to the card. Do not directly touch the backplane with your hand or any metal tool, or you could shock yourself.

Installing the Processor Card

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

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

Caution Make sure blank slot fillers cover all unused slots to ensure proper airflow within the chassis.

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. (See Figure 2-3.)

Caution Handle the processor card by the carrier edges only to prevent ESD damage.

Step 3 Align the processor card with the rails on the inside of the chassis.

Step 4 Carefully slide the processor card into slot 2 (or slot 13 of the Catalyst 5500 switch) until the processor card stops and the ejector levers are protruding outward.

Step 5 Put your thumbs on the left and right ejector levers and simultaneously push inward on the levers to seat the processor card in the backplane connector.

Caution Always use the ejector levers when installing or removing the processor card. A module partially seated in the backplane can cause the system to halt and subsequently crash.

Step 6 Use a flat-blade screwdriver to tighten the captive installation screws on the left and right sides of the processor card.

Step 7 Attach network interface cables or other devices to the interface ports.

Step 8 Turn on the system.

This concludes the procedure for installing the processor card.

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

Connecting the Processor Card to a Network

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

Before connecting the processor card to a network, consider the following:

• 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, refer to the cable pinouts in the appendix "Processor Card Cable and Port Pinouts."

---

Ethernet Port Connections

You need a straight-through Ethernet cable with RJ-45 male connectors (see Figure 2-4) for connection between the Ethernet port and an Ethernet network. Table C-1 in the appendix "Processor Card Cable and Port Pinouts" lists the Ethernet cable connector pinouts.

Auxiliary and Console Port Connections

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 2-5). 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 console and auxiliary 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 is 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 2-6 shows the connectors at the network end of the adapter cable for DCE and DTE connections.

Auxiliary Port Connections

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 C-2 in the appendix "Processor Card Cable and Port Pinouts" lists the signals used on this port.

Console Port Connections

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 C-3 in the appendix "Processor Card Cable and Port Pinouts" 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

Installing and Removing Flash Memory Cards

This section describes how to install and remove Flash memory cards. Flash memory cards ship either installed in the system or as a spare part. When the Flash memory 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.

The processor card includes two Personal Computer Memory Card International Association (PCMCIA) card slots---slot 0 and slot 1---that accept 8-MB, 16-MB, or 20-MB Intel Series 2+ Flash memory cards. The Flash memory card is used to store the system image, and can also be used to store software and microcode images for other systems.

Step 1 Face the front panel of the processor card (see Figure 2-7) and hold the Flash memory card with the connector end of the card toward the slot. The label on the Flash memory card should face up (see Figure 2-7a).

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 2-7b). 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 memory 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 ejector button corresponding to the slot until the card is free of the connector at the back of the slot. (See Figure 2-7c.)

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

This concludes the procedure for installing and removing Flash memory cards.

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 2-8 helps you determine which component of your system might have malfunctioned.

Module 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 processor card LEDs are shown in
Figure 2-9 and described in Table 2-1.
