Figure18: Installing DIMM.
Testing DIMM
The switch is unlikely to boot unless the DIMM is correctly installed. If the
switch does boot but you suspect the DIMM is malfunctioning, enter the
command:
SHOW SYSTEM
to display the system information shown in Figure 19 on page 37. 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 Telesyn
distributor or reseller.
If you have any difficulty with the DIMM at any time, contact your authorised Allied
Telesyn distributor or reseller and quote the serial numbers of both the base card on the
switch and the DIMM. The switch’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.
