Item 2 3 4 5 6 7 Label Indicator SUB-SYSTEM ALARM LED (Red) Description During normal operation, this LED should be off. ON: One or more of the following: The DC is under the voltage of the DKC part. The DC is over current. The temperature is abnormally high. An unrecoverable failure has occurred. If the disk array is set up to report errors to STC, your HP support representative is notified automatically. If the remote support solution is not set up with C-Track remote support, place a service call to HP to have the message evaluated to determine if any action is required. BLINKING: The DC is under the voltage of the DKU part. SUB-SYSTEM MESSAGE LED (Amber) During normal operation, this LED should be off. ON: A service information message (SIM) has been issued from either storage cluster. If the disk array is set up to report errors to STC, your HP support representative is notified automatically. If C-Track remote support is not set up, place a service call to HP to have the message evaluated to determine if any action is required. BLINKING: An SVP failure has occurred. The disk array will continue to operate normally. Place a service call to HP to ensure notification. SVP failures might not be reported automatically to STC. SUB-SYSTEM RESTART Switch If a blocked path occurs between a host and a disk drive, this switch is used to unfence the fenced drive path and to release Write Inhibit. During normal operation, this switch should be in the upper position. Restarting the subsystem performs a soft reset to try to recover. If the system restart does not unblock the path, an HP support representative will be notified. Do not change the switch position unless directed to do so by HP service personnel. REMOTE MAINTENANCE PROCESSING LED (Amber) During normal operation, this LED may be on if remote maintenance is allowed (the REMOTE MAINTENANCE ENABLE/DISABLE switch is in the ENABLE position).

REMOTE MAINTENANCE ENABLE/DISABLE Switch Used to permit remote service maintenance. During normal operation, this switch should be in the ENABLE position. DISABLE: No one can provide remote maintenance. ENABLE: An HP support representative can provide remote maintenance.Do not change the switch position unless directed to do so by HP service personnel. BS-ON LED (Amber) During normal operation, this LED should be on. ON: The disk array is plugged in and receiving power from the primary AC outlet. The SVP is receiving power from the outlet. OFF: The disk array is not receiving power from the primary AC outlet. Check the electrical outlets in your building. 22 HP XP12000 hardware components
