Replacing DIMMs
Caution
There are static-sensitive electronics inside the unit. Before you handle any
parts, make sure you are working at a static-controlled workstation and that you are
properly grounded.
Guidelines for Replacing DIMMs
The Snap Server 4200/4500 provides three DIMM slots, supporting up to 3 GB of
RAM. Before replacing or upgrading your RAM, consider the following guidelines:
• Use only DIMMs supplied by Adaptec —
Adaptec strongly recommends that you
use only DIMMs qualified and supplied by us. Qualified means that Adaptec
technicians have tested and verified that the component operates properly with
the Snap Server.
Caution
Failure to use qualified DIMMs supplied by Adaptec may seriously
impact data availability, could potentially lead to data loss and corruption, and
will void your warranty.
• Do not install DIMMs of different capacity on the same Snap Server —
Each
DIMM you install must carry the same capacity. For example, if your Snap Server
came with a single 512MB DIMM installed, you could install two more 512MB
DIMMs for total of 1.5GB of RAM. To upgrade to 3GB of RAM, you would have
to discard the 512MB DIMM that came with your server, and install three 1GB
DIMMs.
• Install DIMMs in the proper order —
If you are installing fewer than three
modules, make sure you install them consecutively from left to right. Standing at
the rear of the unit, the first slot is the leftmost slot, closest to the power supply.
Shutting Down the Server
Caution
Shut down the server before you make any repairs.
Improper shutdown may
lead to loss of data or physical harm.
