The major features of the UPS include Battery Management Technology
(doubles battery life and speeds recharge time), hot-plug batteries to simplify
service, voltage regulation, power control which enables scheduled shutdowns
and maximized run time, and network surge protection.
The front panel display has user controls (LEDs and control buttons) and the
rear panel contains an RS-232 COMM port which provides UPS status to the
electronics in the controller shelf. The rear panel also contains the network
surge protector and four power receptacles. An audible alarm is activated
when input power fails, as a low battery warning, or whenever the UPS is in
need of servicing. The front panel control switches are used to set the output
voltage level and battery low warning option.
The UPS automatically recharges its battery when power is returned following
a power failure. Recharge time is less than four hours depending on the energy
requirements of your load and the length of the power outage.
Its own installation, operation, and service manual support the UPS. The
manual describes the UPS in detail and is part of the documentation set
enclosed with your storage system.
6-Slot Device Expansion Shelf (Optional)
NOTE: The device expansion shelf must have a revision level of B01 (or higher) to operate
with the controller shelf. Also, the personality I/O module supplied with the shelf
(P/N 70-33067-02) must have a minimum revision level of H01 or higher.
The controller shelf is designed to operate with the device expansion shelf (see
Figure 1– 2). The device expansion shelf is a rackmount enclosure that houses
the storage devices for your storage system installation. The controller shelf
can be connected to one or up to four device expansion shelves, giving the
storage system a maximum capacity of 24 storage devices.
The device expansion shelf is equipped with two AC power supplies, a
personality I/O module that provides the UltraSCSI bus interface, and six
empty slots for storage device SBBs. The user guide for the device expansion
shelf is packaged with the unit and must be used with this document to
properly install and configure the controller shelf.
