Note The ASP installed as an option in the Catalyst 5500 switch is hot swappable; that is, you can install and remove the ASP while the power is on.
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 (0).
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.

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.
Note The ASP ships installed in the LightStream 1010 ATM switch chassis, unless you order it as a spare or as part of an upgrade kit. To remove an existing ASP, refer to the appendix "Maintaining 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.
Note You can also install the ASP as an option in the Catalyst 5500 switch. Slot 13 is reserved for the ASP in the Catalyst 5500 switch. Slots 9 through 12 are used for CMs and PAMs. Refer to the Catalyst 5500 switch documentation for more information.

Step 1 Power off the LightStream 1010 ATM switch, but to channel ESD voltages to ground, do not disconnect the power cable.
Note The ASP installed as an option in the Catalyst 5500 switch is hot swappable.
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.)

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.
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.
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.

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.
Figure 2-5 Auxiliary and Console Ports
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.

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.
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.
Note The console port is an asynchronous serial port; any devices connected to this port must be capable of asynchronous transmission. (Asynchronous devices are the most common type of serial device.)
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:
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 slotsslot 0 and slot 1that 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.
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.
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. Proceed to the section "Configuring Flash Memory Cards" in the chapter "Configuring the ASP" for configuration instructions.
