About this document
This document details procedures for replacing a controller, controller
cache module, or cache batteries in HP StorageWorks Modular Smart
Array (MSA) 1000, 1500 cs, and 1510i products.

Before you begin

CAUTION: Be sure the replacement is available before removing
the failed component. Removing a component impacts airflow and
cooling within the enclosure.
CAUTION: Follow these instructions when replacing components.
If the procedure is done improperly, it is possible to lose data or
damage equipment.
CAUTION:
When handling system components, there is a
danger to equipment from electrostatic discharge (ESD). Use proper
anti-static protection at all times:
• Keep the replacement component in the ESD bag until needed.
•
Wear an ESD wrist strap grounded to an unpainted surface of the
chassis.
• If an ESD wrist strap is unavailable, touch an unpainted surface of
the chassis before handling the component.
• Never touch connector pins.
See your user documentation for additional information.

Verifying component failure

Before replacing a controller, cache module, or battery pack:
•
Check the controller heartbeat LED (1).
If the LED is not blinking, it might indicate a failure.
• Check the controller fault LED (2).
If the LED is on, it might indicate a failure. Check for an error
message listed in Table 1
• Remove the controller, wait 10 seconds, and then reinsert it,
ensuring that it is fully seated in the chassis. If this does not resolve
the issue, continue with the replacement procedures.
