ManualsBrandsHP ManualsStorageHP StorageWorks MSA1500 HP-UX SCSI Starter Kit

1. Locate the controller cover clips (1) on the rear, lower left, and right

sides of the module by holding the controller upright with the latch

handle facing you.

2. Unlatch the controller cover clips (1) on the rear of the controller

and raise the cover (2).

3. Simultaneously unlatch the clips that are holding the cache module

in place (3).

4. Pull the cache module away from the controller board (4).

Step 3: Replace cache batteries

(if applicable)

WARNING! The controller contains Nickel Metal Hydride

(NiMH) batteries. There is risk of explosion, fire, and personal injury if

the battery pack is incorrectly replaced or mistreated. To reduce the

risk of personal injury:

• Do not attempt to recharge the battery.

• Do not expose to temperatures higher than 60

• Do not disassemble, crush, puncture, short external contacts, or

dispose of in fire or water.

• Replace only with HP spare designated for this product.

For more information about battery replacement or proper disposal,

contact your HP Authorized Reseller or your Authorized Service

Provider.

CAUTION: Do not dispose of batteries, battery packs, and

accumulators with general household waste. Use the public collection

system or return them to HP, your authorized HP Partners, or their

agents. For more information about proper disposal, contact an HP

Authorized Reseller or Service Provider.

NOTE: Replace battery packs in pairs, not individually.

NOTE: After replacement, while the batteries are charging, the

cache is disabled. When the batteries are fully charged, the cache is

automatically re-enabled.

1. Push down on the battery retaining clip, located near the lower

corner of the module.

2. Swing the battery pack away from the module to a 30-degree

angle, and then lift the battery pack upward to unhook the top of it.

3. Wait approximately 15 seconds after removing the old battery

pack to allow the battery charge monitor to reset.

IMPORTANT: If you do not wait 15 seconds after removing the

old battery, full charge of the new cache battery is delayed.

4. Repeat step 1 through step 3 in this section to remove the second

battery pack.

5. To install the replacement battery pack, hook the top of the new

battery pack to the top of the module, with the battery held at a

30-degree angle to the plane of the module.

6. Swing the battery downward, ensuring that the bottom clip and

two pegs line up with the holes in the module.

7. Verify that the top hook (1) and bottom clip (2) on the battery pack

are securely attached to the module.

8. Repeat step 5 through step 7 for the second battery pack (3).

Step 4: Install the cache module

(if applicable)

NOTE: When only one cache module is installed, you should

install the module in the bottom slot.

1. Slide the cache module into the controller (1) until the side latches

are fully engaged (2).

2. Close the controller cover.

Step 5: Install the controller

1. Insert the controller into the MSA chassis.

2. Push the controller in as far as it will go (1), and then press the

latch handle inward until it is flush against the front panel (2).

Confirming the firmware version

All MSA configurations

After replacing a controller, verify that the latest firmware for your

MSA is installed. Go to the web site for your MSA, and if newer

firmware is available, download the firmware from the Web and

install this latest version on the controller(s) (Table 3).

Dual-controller configurations

If the firmware versions on the two controllers are mismatched, the

following LCD message might be displayed:

07 CLONE FIRMWARE? ‘<‘ = NO, ‘>’ = YES

Press > to copy the firmware from the active controller to the standby

controller. If < is selected, the standby controller is disabled and the

MSA operates in a non-redundant mode until the firmware on the two

controllers does match.

NOTE:

• MSA1510i—Although rare, if the cache module batteries on a

replacement controller are uncharged and a power interrupt occurs

during the cloning process, the cloning process might fail. To

recover the affected controller, first go to the MSA1510i web site

and obtain firmware. Then, establish a serial connection to the

affected controller, using the custom CLI configuration cable

shipped with the MSA and a terminal emulator program such as

HyperTerminal. (No CLI prompt is displayed.) Using the transfer (or

send file) command of your emulator, send the firmware to the

controller using the XModem protocol. This transfer can take up to

45 minutes. Do not interrupt this process. See the MSA1510i

maintenance and service guide for more information.

• MSA1000/MSA1500 cs—Due to parts availability, replacement

controllers might ship with a new firmware version that is required

for that controller model. If older firmware is installed on the active

controller and newer firmware is installed on the replacement

controller, cloning might fail. To update the firmware on the active

controller, go to the web site for your MSA, obtain the latest

firmware, and update the firmware on both controllers to this latest

version.

Verifying controller status

• Verify that the controller heartbeat LED [Figure 1, (1)] is blinking.

• Verify that the controller fault LED [Figure 1, (2)] is off.

Unread error log messages can cause the fault LED to light.

• Verify that no new error messages are displayed.

Returning the failed controller

Follow the instructions shipped with the replacement.
