Compaq Multi-Server UPS Card

A standard UPS can communicate directly with a single host computer. The Multi-Server UPS Card expands the communications capability of the UPS so that a single UPS that can exchange data with up to three host computers.

Compaq Power Management Software enables a single UPS with a Multi-Server UPS Card to protect up to three servers. Individual server control can be obtained by connecting the servers to different UPS load segments.

For example, if a network includes three servers (with one running Windows NT, one running Unix, and one running NetWare), a Multi-Server Card can be used to establish direct communications between the UPS and all three servers. Use a single UPS load segment to supply power to a particular server and to the devices associated with that server.

Compaq Scalable UPS Card

The Scalable UPS Card makes up to three UPS units appear as a single virtual UPS to the host computer and, with Compaq Power Management Software, allows scaling up the level of power protection available to the system.

For example, connecting three R3000 UPS units to a Scalable UPS Card creates a virtual 9000VA UPS. Since the R3000 UPS each have three load segments, the virtual UPS will have nine independently controlled load segments.

However, no single load can be greater than the lowest rated UPS. For instance, connecting three 1KVA UPSs with a Scalable UPS Card could not support a single 1200VA load.
