Replacing a PROM Component
in a BayStack ARN Router
This document describes how to replace programmable read-only memory
(PROM) components in a Bay Networks
®
BayStack
™
ARN
™
router.
Removing the ARN Cover
To access the BayStack ARN component tray:
1.
Be sure that power is turned
off
, to the 0 position.
2.
Unplug the ARN power cord from the wall receptacle.
3.
If present, unplug the redundant power supply cable from the ARN.
4.
Remove all console cabling from the back panel.
5.
Remove all network cabling from the front panel.
6.
Loosen the two captive screws that secure the enclosure to the ARN
component tray (Figure 1)
.
Be sure to loosen these screws all the way.
Danger:
A potential energy hazard exists during the upgrade procedure if you
fail to unplug the ARN. Make sure you unplug the ARN before you proceed.

7.
Holding the ARN front panel so that it does not move, slide the enclosure
away from the component tray.
8.
Place the ARN component tray on a stable, static-free work surface.
9.
Attach an antistatic wrist strap.
You receive an antistatic wrist strap with the ARN system and with the
upgrade module shipment. Refer to the instructions in the wrist strap bag.
The wrist strap directs the discharge of static electricity from your body to the
router chassis, thereby avoiding discharge to sensitive electronic components.
10.
If present, remove an installed Ethernet data collection module (DCM).
Go to the next section if the ARN does not contain a base module DCM.
a.
At one of the three plastic standoff mounts, press in on the clip that
secures the DCM (Figure 2)
and simultaneously pull up to release the
module from the mount.
b.
Release the module from the other two mounts.
c.
With the DCM free from all three standoff mounts, grasp either end
of the DCM connector and pull straight up to detach the DCM from
the base module socket.
Use some force at first, but stop pulling once the two connectors are free.

2.
Attach the antistatic wrist strap that came in your upgrade kit.
3.
Using the PROM puller tool that came in the upgrade kit, remove the
PROM component installed in the base module socket labeled U-10.
a.
Insert the puller tool diagonally through the slots at the corners of the
socket (Figure 4)
.
b.
Squeeze the puller tool to grasp the bottom of the PROM; then,
gently lift the PROM up.

Installing the Replacement PROM Component
Install a new PROM components as follows:
1.
Remove the new PROM from its antistatic bag.
2.
Holding the PROM with two fingers, align the dot on the component with
the arrow on the socket (Figure 6)
.
Install the new base module PROM component in location U10 (refer to
Figure 3
). If applicable, install the new expansion module PROM component
in location U15 (refer to Figure 5
).
3.
Gently push the PROM into place with your thumb.

Reinstalling the BayStack ARN
1.
Slide the ARN component tray back panel into the chassis.
2.
Tighten the captive thumb screws.
3.
Place the MD-801C version label next to the ARN revision label.
4.
Reconnect the cables to the back panel of the ARN.
5.
Plug the power cord into the wall socket to power on the ARN.
6.
Verify that the ARN starts up correctly by watching the front panel
LEDs.
A successful boot results in a steady Run LED.
7.
If the boot is unsuccessful, connect a console to the ARN to review
diagnostic messages.
For information about reading the LEDs, connecting a console, and reviewing
diagnostic messages, refer to Installing and Operating BayStack ARN Routers.
Note:
Bay Networks requires that you apply the ARN PROM Upgrade version
label after you install the upgrade. It is important for future service that you
complete this step to identify the ARN as having this upgrade.
