Network Configurations
There are several configuration options when using Compaq UPSs to protect a Local Area
Network (LAN).
Server or Single Workstation Only
For those seeking basic protection,using one UPS to protect a single server or single work-
station is considered sufficient.In case of a power failure,data integrity is maintained.The data,
however,is not accessible by unprotected servers or workstations until normal power is resumed.
Central UPS for Server and Nodes or Total Multi-User
Environment
Use of one central UPS is recommended for more critical LAN environments when each
workstation’s processing transactions must be kept current and where workstation location
does not require special wiring or use of extension cords to connect to the UPS.This single
UPS must not only support all connected equipment, but also must be large enough to
allow for future expansion.
Multiple UPSs for Server and Nodes or Individual Workstations
Using multiple UPSs is recommended in the most critical real-time processing environ-
ments.It is often the most practical option for both financial and safety reasons and
requires no special wiring.In addition,as the LAN grows,additional UPSs are added to
each workstation location,instead of replacing an outgrown unit.
Multiple Servers with One UPS
Connecting one UPS to more than one server is practical in applications where there are
multiple servers in close proximity to one another (especially common in rack cabinet
configurations).In such cases,it may be more economical or a space-saving advantage to
use one larger UPS instead of two smaller ones to back up multiple servers.
