Warning Read the installation instructions before you connect the system to its power source.

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units.

Safety Recommendations

Follow these recommendations when installing the ASP to help ensure your safety and protect the equipment:

• Clear the chassis area and keep it dust-free during and after installation.
  
  
• Store tools and chassis components away from walk areas.
  
  
• 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.
  
  
• Power off the system before removing the ASP. The ASP is a required system component. Removing an ASP from a LightStream 1010 ATM switch while the system is operating causes the system to shut down and might damage the processor.
  
  

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 and can cause serious burns or weld the metal object to the terminals.

Warning Before working on a system that has an on/off switch, turn off the power and unplug the power cord.

Warning This unit might have more than one power cord. To reduce the risk of electric shock, disconnect the two power-supply cords before servicing the unit.

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 carrier modules (CMs), port adapter modules (PAMs), 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. However, you must power off the system before removing the ASP. Before removing a redundant power supply, ensure that the first supply is powered on (|) and the power supply being removed is powered off (O).

Follow these guidelines when working with any electrical equipment:

• Locate the emergency power-off switch for the room in which you will be working before accessing the chassis interior.
  
  
• 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.
  
  
• Examine your work area carefully for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
  
  

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 ASP and PAMs each consist 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 ASP or PAMs. Handle the carriers by the carrier edges only; never touch the cards or connector pins.

Follow these guidelines to prevent ESD damage:

• Handle carriers by the faceplates and carrier edges only; avoid touching the card or any connector pins.
  
  
• Place a removed card component side up on an antistatic surface or in a static shielding bag. If you are returning a 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 a 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).

Installing the ASP

This section describes how to install the ASP in both the LightStream 1010 and the Catalyst 5500 chassis. The process to install the ASP in both chassis is essentially the same, but unlike the Catalyst 5500, the LightStream 1010 chassis does not support hot swapping the ASP. You must power off the Lightstream 1010 chassis before removing or installing the ASP. The Catalyst 5500 supports hot swapping the ASP.

The LightStream 1010 ATM switch is a five-slot modular chassis. Slot 2 is reserved for the ASP, as shown in Figure 2-2. The other four slots are used for CMs and PAMs.

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

To install the ASP, take these steps:

Step 1   Power off the LightStream 1010 ATM switch, but to channel ESD voltages to ground, do not disconnect the power cable.

Caution The ASP is a required system component. Removing or installing an ASP while the LightStream 1010 ATM switch is operating causes the system to shut down and might damage the processor. Power off the system before removing or installing the ASP.

Step 2   Hold the ASP faceplate with one hand, and place your other hand under the carrier. Avoid touching the components on top of the card. (See Figure 2-3.)

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

Step 3   Align the ASP with the rails on the inside of the chassis.

Step 4   Carefully slide the ASP into slot 2 (or slot 13 of the Catalyst 5500 switch) until the ASP 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 ASP in the backplane connector.

Caution Always use the ejector levers when installing or removing the ASP. 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 ASP.

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

Step 8   Power on the LightStream 1010 ATM switch.

This concludes the procedure for installing the ASP.

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 ASP to a Network

This section describes how to connect the ASP to a network and includes the following subsections:

• Ethernet Port Connections
  
  
• Auxiliary and Console Port Connections
  
  

Before connecting the ASP 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). Before installing the switch, 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 "ASP Cable and Port Pinouts."
  
  

Ethernet Port Connections

You will 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 "ASP Cable and Port Pinouts" lists the Ethernet cable connector pinouts.

Auxiliary and Console Port Connections

The ASP 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 switch 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 ASP is a male, EIA/TIA-232, DTE, DB-25 plug. You can attach a CSU/DSU or other device to access the switch 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 "ASP Cable and Port Pinouts" lists the signals used on this port.

Console Port Connections

The console port on the ASP 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 "ASP Cable and Port Pinouts" lists the signals used on this port.

Before connecting to the console port, check your terminal's documentation to determine the baud rate. The baud rate of the terminal 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 a LightStream 1010 ATM switch or as a spare part. When the Flash memory card is shipped installed in a LightStream 1010 ATM switch, the card contains a system image. When the card is shipped as a spare part, it is unformatted; you must format the card before it is used.

The ASP includes two Personal Computer Memory Card International Association (PCMCIA) card slots—slot 0 and slot 1—that accept 8-, 16-, 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.

To install and remove the Flash memory card, take these steps:

Step 1   Face the front panel of the ASP (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 ASP; a portion of the card remains outside of the slot. Do not attempt to force the card past this point.

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. Proceed to the section "Configuring Flash Memory Cards" in the chapter "Configuring the ASP" for configuration instructions.
