Removing an Array Controller DIMM
(HP Service Personnel Only
)
Caution
DIMMs can be damaged by electrostatic discharge. Use the ESD
kit provided when removing and installing DIMMs.
The following procedures are used when removing/installing
DIMMs on a single controller. If you are upgrading the DIMMs
on both controllers, you must shutdown the array. See
"Upgrading Array Controller DIMMs" on page 135
.
1
Remove the array controller card. See
"Removing an Array Controller" on
page 107
.
2
Remove the battery. See
"Removing an Array Controller Battery" on
page 117
.
Caution
The battery must be removed to ensure there is no power to the
DIMMS and to prevent damage to DIMMs caused by voltage
spikes. After removing the battery, wait 2 minutes before
removing DIMMs. This allows any residual charge to drain from
the DIMMs.
3
Use your thumbs to pull out both DIMM extraction levers (
Figure 48
, 1) at
the same time. The DIMM will automatically pop out of the DIMM slot.
4
Remove the DIMM (2) from the slot.

Caution
—
DIMMs can be damaged by electrostatic discharge. Use the ESD kit
provided when removing and installing DIMMs.
—
To avoid interference when installing DIMMs, always load the DIMM 1
slot first (see
Figure 48
, 2).
—
Controller firmware 13 and earlier supports a maximum of 1 Gbyte of
cache memory per controller. Installing more than 1 Gbyte of memory
can cause data loss.
—
Replacement DIMMs must have the same memory size as the DIMMs
being replaced. Otherwise, the array controller will report a “Memory
Mismatch”. If the array is powered-on after the array controller is
