Installing an Array Controller
(HP Service Personnel Only)
Caution If the green BATTERY LED is flashing and you remove a DIMM,
damage to the array controller or DIMM may occur.
Do not use a controller that has HP14 firmware as a replacement
if the remaining controller has an earlier version of firmware.
Earlier versions of firmware cannot overwrite HP14 firmware.
Replacement controllers ordered from HP have HP13 or earlier
firmware on them. If you are unsure of the firmware version on
the controller, do not use it as a replacement.
1 If the green BATTERY LED on the new or upgrade array controller is off, go
to step 2. If the green BATTERY LED on the new or upgrade array controller
is flashing with a 5% duty cycle (battery fully charged), disconnect the
battery from the battery terminal. See "Removing an Array Controller
Battery" on page 117 . Reconnect it and verify that the green BATTERY LED
is off.
Note Disconnecting the battery from the array controller resets a bit
on the controller which disables battery power to the DIMMs.
2 Either install new DIMMs (ordered separately) on the new array controller
or transfer functional DIMMs from the old controller. See "Installing an
Array Controller DIMM" on page 120 .
