Compaq Multi-Server UPS Card

In addition to the UPS options listed, Compaq also offers the Extended
Runtime Module (ERM), Compaq part number 347224-B21, for use
with the Compaq 6000 Series UPS (with two option slots). This 3U rack
option significantly expands the available battery runtime of the already
powerful 6000 Series UPS.

With the Compaq Multi-Server UPS Card, system administrators can serially
connect up to three devices to a single UPS, permitting multi-protocol and
out-of-band communication for networks with multiple servers or disparate
operating systems.
For example, a business running Novell, Windows NT, and Unix servers does
not have to acquire an individual UPS for each piece of equipment. Instead,
the Multi-Server UPS Card is installed, enabling direct communication with
multiple devices even when the network is down.
By adding a single Multi-Server UPS Card to a UPS, the UPS can
independently communicate with up to three servers with different rating
systems and shutdown schedules. If the UPS has two slots, like the Compaq
6000 Series UPS, two Multi-Server Cards can be installed to enable
communication with up to five servers. Even if the network goes down, this
option enables out-of-band communication to each server, allowing a graceful
shutdown of the operating system.
