If you encounter any abnormality such as an abnormal sound, smell, or smoke, power off the disk subsystem by operating the UNIT EMERGENCY POWER OFF switch following the procedure below. The procedure for operating the switch is as follows: 1. Push the control panel cover at the portion where PUSH is marked, open the control panel cover, then operate the UNIT EMERGENCY POWER OFF switch. In using a UNIT EMERGENCY POWER OFF switch, first pull it up and then pull it toward you as illustrated in figure 10 (page 56). Caution Pulling the UNIT EMERGENCY POWER OFF switch on the disk array cabinet instantly shuts down the array, neglecting the system's power-off sequence. Jobs in process are aborted and their integrity after recovery is not guaranteed. Therefore, this method should be used only in an emergency and not in normal operation. Caution The UNIT EMERGENCY POWER OFF switch on the disk array cabinet only partially restores power from the array. AC input power remains present at the primary circuit. Therefore, do not use the UNIT EMERGENCY POWER OFF switch unless you need to power off the unit as an emergency measure. When pulled, a UNIT EMERGENCY POWER OFF switch locks itself to prevent further powering on and requires a trained and qualified HP field engineer for recovery.

Pulling the UNIT EMERGENCY POWER OFF Switch 56 HP SureStore E Disk Array XP512/XP48: Owner's Guide Normal Operations The disk array does not require intervention from the user. The disk array reports any remote error messages (R-SIMs) to your remote console PC and also sends the report to the HP Service Center automatically. The RC software allows the HP Service Representative to view the R-SIMs by date and time or by controller and to manage the R-SIM log file on the remote console PC. For more information on SIMs, see "Troubleshooting" (page 77). The HP SureStore E Disk Array XP48 Hardware 57 Powering Off the Disk Array Situations may arise in the operation of the disk array that require the user to power off the disk array. These situations include: · UNIT EMERGENCY POWER OFF · Planned power-off UNIT EMERGENCY POWER OFF An emergency is a critical situation such as a physical plant catastrophe such as a flood, hurricane, tornado, or a threat of injury or death to a person. In an emergency, the critical need is to quickly remove power from the disk array. In an emergency, the operator should trip the UNIT EMERGENCY POWER OFF switch. The disk array UNIT EMERGENCY POWER OFF switch is located on the control panel. Caution Use this switch only in case of an emergency. An HP Service Representative is required to reset the UNIT EMERGENCY POWER OFF and to power on the disk array. To power off the disk array in an emergency: 1. Open the control panel cover by pushing on the point marked PUSH. [. . . ] LCP is identical to that used in the DKC90.
