HP MSA 2040 Replacement Instructions page 2

Moving side brackets to the replacement
chassis
1. Remove the side bracket from each side of the failed
chassis.
2. Attach the side bracket to each side of the
replacement chassis.
Moving power and cooling modules to the
replacement chassis
1. Remove the power and cooling modules from the
failed chassis:
a. Turn the thumbscrew until the screw disengages
from the module (1).
b. Rotate the latch downward to disconnect the
module from the internal connector (2).
c. Pull the module straight out of the chassis (3).
2. Install power and cooling modules in the
replacement chassis.
With the latch in the open position, slide the module
into the chassis as far as it will go and rotate the
latch upward to engage the module with the internal
connector. Then, turn the thumbscrew finger-tight.
Moving controller, I/O, or air management
modules to the replacement chassis
IMPORTANT: Modules must be reinstalled in the
same bays from which they were removed.
Installing a module in a bay other than the one
from which it was removed may result in loss of
access to the storage.
1. Remove the modules from the failed chassis:
a. Turn the thumbscrews until the screws
disengage from the module (1) and rotate both
latches downward to disengage the module
from the internal connector (2).
b. Pull the module straight out of the chassis (3).
2. Install the modules in the replacement chassis.
With the latches in the open position, slide the
module into the chassis as far as it will go. Rotate
the latches upward to engage the module with the
internal connector, and then turn the thumbscrews
finger-tight.
Installing the replacement chassis in the rack
1. Support the bottom of the chassis and place the
chassis in the rack.
2. Secure the chassis to the rack.
3. Install the ear bezels by aligning each bezel with
the ball nuts on the chassis ear and pressing firmly
until the bezel clicks in place.
Installing drive or drive blank modules in the
replacement chassis
IMPORTANT: Reinstall each drive or drive blank
module in the same bay number from which it
was removed.
1. With the latch in the open position, slide the module
into the drive slot as far as it will go (1).
2. Rotate the latch closed until it clicks (2).
Completing the process
1. Reconnect data cables to the original cabling
configuration. As needed, connect cables:
Between cascaded drive enclosures.
Between the first and last drive enclosure and
the controller enclosure.
Between the controller enclosure and the host.
2. Reconnect power cords to the devices.
3. Turn on power and cooling module switches (if
present).
4. Restart system devices in the following sequence,
allowing time for each device to complete its Power
On Self Tests (POST) before proceeding:
a. Drive enclosures
b. Controller enclosures
c. Hosts
5. Perform a rescan to force a fresh discovery of all
drive enclosures connected to the controller
enclosure. This step clears the internal SAS layout
information and reassigns enclosure IDs based on
the cabling sequence. This ensures that the
enclosures are numbered correctly.
To perform a rescan using the SMU, in the
Configuration View panel, right-click the system and
select Tools>Rescan Disk Channels. Then, click
Rescan.

Verifying operation
View LEDs on the front of the chassis and on each
module. For detailed LED information, see the user guide
for your model controller enclosure or drive enclosure.
Drive modules: Verify that the Online/Activity LED
(bottom LED) is green.
Power and cooling modules: Verify that the Input
Power Source Good LED (top LED) is on.
Controller modules and I/O modules: Verify that
the OK LED is on, indicating that the module has
completed initializing and is online.
Chassis front panel: Verify that the Heartbeat LED
is green and that the Fault LED is off.
Returning failed items
In materials shipped with the replacement, HP specifies
if the failed component must be returned. Follow the
provided instructions.
