10.0 Details of Installation
Attention.
The System Card is not hot pluggable.
Electrostatic discharge (ESD) can damage the static-sensitive devices on circuit boards. To avoid
this kind of damage, use the following precautions:
•Do not remove the DIMM until you are ready to insert it into the Multiaccess Enclosure.
•Use correct grounding techniques when inspecting and installing the DIMM. Use a foot strap or
grounding mat, or wear a grounded static discharge wrist strap, or touch a grounded rack or
other source of ground before you handle the DIMM.
10.1 Removing the System Card
1. Switch OFF each power supply.
2. Unplug the cables from the system card.
3. Loosen thumbscrews on the system card.
4. Remove the system card and lay it on a
soft non-conductive surface.

10.2 Adding a DIMM on the System Card
1. Remove the DIMM, in its antistatic bag, from its shipping container.
2. Remove the DIMM from the antistatic bag. Inspect it for damage.
Always handle the DIMM by the ends (preferably grasp it between the
middle finger and thumb; do not touch the components). If the DIMM
appears to be damaged, return it to the antistatic bag and contact the
supplier.
3. On the System card, Locate the DIMM sockets (Slots U87 and U86 -
Refer to figure below).
Note: Any slot can be used to install the first DIMM.
4. Insert the DIMM into the free slot. (Grasping the DIMM between the
middle finger and thumb, place it connector edge down into the DIMM
socket. Applying slight pressure to the top edge of the DIMM, move it
forward until it is correctly aligned and snaps in place.)
The lever will snap back into place as the DIMM is fully inserted.
10.3 Re-installing the System Card
1. Re-install the new system card. Make sure the card is aligned with the
plastic grooves and then slide it in until it is flush with the box. Hold the
locking latches so that they are perpendicular to the face of the system
card. With the card in full contact with the rear of the Multiaccess Enclo-
sure, press the locking latches into the system card.
2. Tighten the thumbscrews on the face of the adapter card clockwise.

Power Supply Status
System Card Status
Adapter Card Status
LEDs Meaning
Yellow
(Overcurrent) On - There is an overcurrent condition with the −48 V to one or more of the adapters (slots 1−8) or the +12 V to the fan tray.
Green DC On - +5 V, +12 V, and −48 V are OK.
Green AC On - AC source voltage is present and within tolerance.
LEDs Meaning
PCMCIA 1 or
PCMCIA 2
(Yellow)
On - PCMCIA device has a fault, is not installed, or is not seated
correctly.
Off - Device passed self-tests
OK (Green) On - Card hardware is operating normally.
Blinking - Loading from hard file
OK (Yellow) On - Card hardware has a fault.
Fault Hard Drive
(Yellow) On - Hard drive has failed.
LEDs Meaning
OK (Green) On - Adapter is operating normally.
OK (Yellow) On - Adapter has a fault.
Wrong slot
(Yellow) On - Adapter is in the wrong slot.
The wrong slot LED is ON only when an adapter that is plugged
into the multiaccess enclosure violates the plugging rules.
Green port (See
note). On - Port is operating normally (enabled and configured). Off - Port is not configured or is disabled.
For the ESCON adapter:
Blinking - The optical power measurement test is running.
Yellow port (See
note). On - One or more ports has a hardware fault. Blinking - One or more ports has a port I/O or network failure.
Use the Maintenance Analysis Procedures (MAPs) to isolate.
Off - No problem detected.
Note: The port LEDs of the multiport WAN adapters (FC 3282, FC 3291, and FC 3292)
reflect the status of one or more of the ports.
