AT-9800 Series Switch

Installing DIMM
AT-9800 Series switches have one DIMM slot. The slot can be populated with
either a 128 MByte DIMM or a 256 MByte DIMM.
Warning
Only Allied Telesis supplied DIMMs have been tested and approved
for use with AT-9800 Series switches. Using DIMM that has not been tested and
approved may cause unreliable operation and will invalidate the switch’s
warranty.
Warning
For AT-9800 Series switches, DIMM should only be installed by
authorised service personnel. Unauthorised opening of the switch’s lid may
cause danger of injury from electric shock, damage to the switch, and
invalidation of the product warranty.
To install DIMM in an AT-9800 series switch:
1.
Avoid injury by working in a safe environment.
The workspace should be free of hazards, and there should be sufficient
room to lay out the switch, DIMM, and tools.
2.
If fitted, disconnect the switch’s redundant power supply.
3.
Disconnect the mains power cord.
Warning
Before removing the switch’s lid, the power cord and, if connected,
RPS power cord should be disconnected to reduce risk of electrical shock.
4.
Remove all interface cables.
5.
Remove the switch’s lid.
The switch may need to be removed from any rack mounting system
before its lid can be removed.
Using a posidrive screwdriver, remove the 12 screws that secure the
switch’s lid. There are 5 screws located in countersunk holes on each side
of the lid, and 2 screws at the rear.
6.
Prepare the DIMMs.
In an antistatic environment, remove the DIMM from its packing material.
Be sure to observe ESD precautions.
Warning
Do not attempt to install DIMM without observing correct antistatic
procedures. Failure to do so may damage the DIMM and switch. If you are
unsure what the correct procedures are, contact your authorised Allied Telesis
distributor or reseller.
7.
Remove the existing DIMM.
Warning
Before removing the switch’s lid, the power cord and, if connected,
RPS power cord should be disconnected to reduce risk of electrical shock.
The DIMM is held in place by two retaining latches, one latch at each end
of the DIMM slot. Release these latches and carefully pull the DIMM from
the DIMM slot.
