General Operating Instructions

Please read the following instructions carefully. They contain information on how to avoid data loss and damage to the system due to improper handling.

Reset Switch

The front panel’s reset switch resets the power supply, performs a self test, and can be used to set the unit identification number.

Power Supply Reset

If the power supply shuts down, momentarily pressing the reset switch initiates a power supply reset. The reset sequence takes about 15 seconds. The display and power-on LED are off during the reset sequence.

Self-Test

When a self-test is performed, the results are displayed on the LED. To perform a self-test, complete the following procedure:

1.With the power switch off, hold the reset switch and turn the power on.

2.Release the reset switch. The seven-segment LED blinks “8.8.” five times, then displays the firmware revision number. The unit then performs a power supply reset, as described above.

Unit Identification Number

A unit identification number can be set for identification purposes. It has no impact on the operation of the storage system. To change the unit identification number, complete the following procedure:

1.Press and hold the reset switch for approximately five seconds, until the LED starts its count (at one-second intervals). The numbers 1 through 16

and the letters “HP” display in sequence (“HP” is the default unit identification number).
