Testing DIMM
The switch is unlikely to boot unless the DIMM is correctly installed. The
switch controller’s fault LED will flash slowly if the DIMM is not detected. The
fault LED will flash quickly if the DIMM is not of an acceptable type.
If the switch does boot but you suspect the DIMM is malfunctioning, or if you
hot swapped in a switch controller with new DIMM, enter the command:
SHOW SYSTEM
to display the system information shown in Figure 9 on page 55. In the
output’s memory section there should be an entry showing the size of DRAM.
If the DRAM size is less than the size of DIMM that has been installed, then the
switch has not correctly detected the DIMM. The most likely cause is that the
DIMM connector is not plugged into its slot correctly. Repeat the installation
process, paying particular attention to the DIMM insertion step.
After repeating the installation, use the SHOW SYSTEM command again, and
if the display is still not correct, contact your authorised Allied Telesis
distributor or reseller.
If you have any difficulty with the DIMM at any time, contact your authorised Allied
Telesis distributor or reseller and quote the serial numbers of both the base card on the
switch controller and the DIMM. The switch controller’s serial numbers and revision
details can be read using the SHOW SYSTEM command. It’s a good idea to record this
information for later reference.
