One accelerator card
Warranty card
If any of these components are damaged, contact your shipping carrier representative. If any components are missing, please phone the Allied Telesyn. Refer to Appendix D, “Where To Find Us,” on page 23.

Prerequisites for Card Installation

Before installing the uplink and accelerator cards, make sure you have the following:
An installed FORMULA 8200 switch and that it is functioning properly
Firmware version 1.4.3 or greater to support the uplink and accelerator cards
If your switch does not have the latest firmware, download it from Allied Telesyn’s FTP server. See Appendix D, “Where To Find Us” on page 23, for information on how to access the server.

AT-8202 and AT-8203 Installation Guide

Installing the Uplink Card

Caution Prior to installing the uplink card, make sure you have successfully installed the FORMULA 8200 switch with firmware version 1.4.3 or greater, and that it is functioning properly.
You will need a #1 Phillips screwdriver for this procedure. To install the uplink card in the FORMULA 8200, use the following steps:
1. Turn off power to the FORMULA 8200.
The power switch is located on the rear panel of the chassis, as shown in Figure 3.

When installing or removing cards in a switch, always remove all power by unplugging the unit.
3. Disconnect and label all connections to the switch, if present.
To install the uplink card, you must take the top cover off of the switch. To remove the top cover, it may be necessary to remove the switch from the rack or tabletop location.

4. Remove additional hardware, such as rackmounting brackets.
Note
If the switch is installed on the desktop, you need not remove the rubber feet.
Warning
Use proper static-free procedures prior to opening the unit and touching components.
5. Remove the top cover from the unit, as follows: a. Remove the screw from the back of the unit that locks the cover in
place. Retain the screw for replacing the cover later.
b. Lift the cover and slide it off (Figure 4).

Replacing the Chassis Top Cover

Replacing the Chassis Top Cover
1. Slip the back of the cover over the back chassis rails, as shown in Figure 10.

2. Lower the cover onto the chassis, being careful to align the latches along the chassis sides with the latch cutouts on the cover.
3. Once the cover is in position, gently push it forward toward the front bezel until it latches into position.
4. Secure the cover by inserting and tightening the original screw you removed from the back when you took the cover off in Step 5 on page 6.
5. Reattach rackmount brackets if applicable, and return the unit to the rack, bench, or table.

AT-8202 and AT-8203 Installation Guide

Initializing the Switch

1. Connect a terminal to the switch’s console port so you can monitor the boot process. Refer to your procedures.

2. Apply power to the switch. The switch firmware runs post diagnostics where it decompresses data

and loads it into the DRAM. The process takes about 15 to 20 seconds. During switch initialization, watch for the following messages that
indicate the successful installation of the uplink and accelerator cards:
Attaching network interface lo0... done.
Initializing accelerator... done.
3. Reattach the network cables to the ports, one at a time, beginning with
the leftmost port. Observe that port’s LED to ensure normal operations; then, attach the cable to the next port.
Attaching the cables one at a time and ensuring link stability helps you isolate problems in case some links may have problems.
This completes the uplink card and accelerator card hardware installation.

Interpreting the LEDs

Interpreting the LEDs
The ATM uplink card has one link LED. If there is a valid link, the LED is solid green. If the uplink card is not connected to any device, or there is a problem with the link, the LED is off.
The FDDI uplink card has two LEDs. Table 1 provides information about what the LEDs mean in various states.
