Unit identification (UID) button The unit identification (UID) button helps locate an enclosure and its components. When the UID button is activated, the UID on the front and rear of the enclosure are illuminated. NOTE: A remote session from the management utility can also illuminate the UID. • To turn on the UID light, press the UID button. The UID light on the front and the rear of the enclosure will illuminate solid blue. (The UID on cascaded storage enclosures are not illuminated.) • To turn off an illuminated UID light, press the UID button. The UID light on the front and the rear of the enclosure will turn off. Power on/standby button The power on/standby button applies either full or partial power to the enclosure chassis. • To initially power on the enclosure, press and hold the on/standby button for a few seconds, until the LEDs begin to illuminate. • To place an enclosure in standby, press and hold the on standby button for a few seconds, until the on/standby LED changes to amber. NOTE: System power to the disk enclosure does not completely shut off with the power on/standby button. The standby position removes power from most of the electronics and components, but portions of the power supply and some internal circuitry remain active. To completely remove power from the system, disconnect all power cords from the device. SAS cables These disk enclosures use cables with mini-SAS connectors for connections to the controller and cascaded disk enclosures. Controller enclosure For both the P63x0 EVA and P65x0 EVA, a single enclosure contains a management module and two controllers. Two interconnected controllers ensure that the failure of a controller component does not disable the system. One controller can fully support an entire system until the defective controller, or controller component, is repaired. The controllers have an 8 Gb host port capability. The P63x0 and P65x0 EVA controllers are available in FC, FC-iSCSI, and iSCSI/FCoE versions. The controller models are HSV340 (for the P63x0) and HSV360 (for the P65x0). Figure 1 (page 22) shows the bezel of the controller enclosure. Figure 2 (page 22) shows the front of the controller enclosure with the bezel removed. Controller enclosure 21

Unit identification (UID) button
The unit identification (UID) button helps locate an enclosure and its components. When the UID
button is activated, the UID on the front and rear of the enclosure are illuminated.
NOTE:
A remote session from the management utility can also illuminate the UID.
•
To turn on the UID light,
press the UID button. The UID light on the front and the rear of the
enclosure will illuminate solid blue. (The UID on cascaded storage enclosures are not
illuminated.)
•
To turn off an illuminated UID light,
press the UID button. The UID light on the front and the
rear of the enclosure will turn off.
Power on/standby button
The power on/standby button applies either full or partial power to the enclosure chassis.
•
To initially power on the enclosure,
press and hold the on/standby button for a few seconds,
until the LEDs begin to illuminate.
•
To place an enclosure in standby,
press and hold the on standby button for a few seconds,
until the on/standby LED changes to amber.
NOTE:
System power to the disk enclosure does not completely shut off with the power on/standby
button. The standby position removes power from most of the electronics and components, but
portions of the power supply and some internal circuitry remain active. To completely remove
power from the system, disconnect all power cords from the device.
SAS cables
These disk enclosures use cables with mini-SAS connectors for connections to the controller and
cascaded disk enclosures.
Controller enclosure
For both the P63x0 EVA and P65x0 EVA, a single enclosure contains a management module and
two controllers. Two interconnected controllers ensure that the failure of a controller component
does not disable the system. One controller can fully support an entire system until the defective
controller, or controller component, is repaired. The controllers have an 8 Gb host port capability.
The P63x0 and P65x0 EVA controllers are available in FC, FC-iSCSI, and iSCSI/FCoE versions.
The controller models are HSV340 (for the P63x0) and HSV360 (for the P65x0).
