DIMM installation procedure
To install a DIMM, complete the following steps:
Step 1. Before you begin, read “Safety” on page iii and “Installation guidelines” on page 23.
Step 2. Read the documentation that comes with the DIMMs.
Step 3. Locate the DIMM connectors (see “Blade server connectors - BladeCenter HX5” on page 20).
Determine the DIMM connector into which you will be installing memory.
Step 4. If another memory module is already installed in the DIMM connector, remove it (see “Removing a
DIMM - BladeCenter HX5” on page 43).
Step 5. Touch the static-protective package that contains the DIMM to any
unpainted
metal surface on the
BladeCenter unit or any
unpainted
metal surface on any other grounded rack component in the
.
