Installing DIMMs
Caution: Failure to al ow the ports to quiesce can
result in data loss. Quiescing can take several
minutes.
Use the following steps to install DIMMs in a cache module in
dual-redundant configurations:
The ECB must be disabled before disconnecting the ECB
cable from the cache module. Failure to disable the ECB
might result in cache module damage.
Note: Before instal ing DIMMs, note the fol owing:
■
New cache modules arrive without DIMMs installed; the DIMMs
are packaged separately. Unpack the DIMMs and instal them
into the cache module as required.
Note: A countdown timer allows a total of 2 minutes to remove the
cache module. After 2 minutes, “this controller” exits FRUTIL and

page 2 for valid cache module memory configurations.

Some HSG80 controller configurations require a 512-MB
cache memory configuration. Make sure the cache memory
configuration meets or exceeds the ACS requirement. See
