Troubleshooting

4.3.1 Audible Alarm Mute

When the Audible Alarm sounds, it may be muted by pressing the Alarm Mute push-button until a double beep is

heard (approximately 1 second). The Alarm Mute push-button is located beneath the indicators on the Operator

Panel (see Figure 4–1).

When the alarm is muted it will continue to sound with short intermittent bleeps to indicate that a problem still

exists, It will be silenced when all problems are cleared. (See also Thermal Shutdown states, Section 4.5.5).

4.4 Test Mode

A Test Mode is available whenever there are no faults present within the sub-system. In this mode the Amber and

Green LEDs on each of the drive carrier modules are flashed on and off in sequence.

To Activate Test Mode (with no other faults present)

Press the Alarm Mute push-button until a double beep is heard. The LEDs will then flash until reset, either by

pressing the Alarm Mute push-button again or if any actual fault occurs.

4.5 Troubleshooting

The following sections describe common problems, with possible solutions, which can occur with your SS-1200-

FCAL system.

4.5.1 System Faults

Note See also Section 4.5.5.

Symptom Cause Action

1 The SYSTEM LED will

illuminate AMBER

2 Audible Alarm sound

The ESI processor has detected

an internal fault (e.g. failure of

an internal communications

path)

1 Check for other AMBER LED

indications on the Power Supply/Cooling

modules. If there is a PSU error present

there may be a communications problem

with that Power Supply/Cooling module.

Remove and then re-fit the module, if the

problem persists then change the module.

2 Check for other AMBER LED

indications on the drives carriers. If none

are evident then there may either be an

ESI processor problem or a Backplane

problem.

3 Change the ESI/Ops Panel module (see

4.9.2).
