Overview
1-9
Communications Port
The 3000 Series UPS includes a communications port for data exchange with
the host computer. The power management software supplied by Compaq
enables the user to access status reporting and power management features.
CAUTION:
Use only cables supplied by Compaq to connect the communications
port to the host computer. Use of standard RS-232 cables may cause equipment
damage.
Power Management Software
With each UPS, Compaq supplies a CD containing several power management
software applications, to address a variety of installations:
■
Compaq Power Management Software is a comprehensive Microsoft
Windows-based power management application that is tightly integrated
with Compaq Insight Manager.
■
LanSafe III provides UPS power management capabilities in a network
environment.
■
FailSafe III provides UPS power management capabilities in a
standalone computer environment.
■
Compaq OnliNet Centro provides UPS power management capabilities
in a multi-platform network environment (supplied only with the
Compaq SNMP-EN Internal Adapter).
Compaq Power Management Software
Compaq Power Management Software allows system administrators to
monitor, and to manage, the power being supplied to an entire network of
servers and workstations.
Software capabilities include:
■
Monitoring utility power, and the power supplied by the UPS.
■
Logging events, such as utility power blackouts and brownouts.
■
Prioritizing protected devices.
■
Powering up and powering down protected devices.
For example, if Compaq Power Management Software detects an extended
utility power blackout, it will initiate the prioritized shutdown sequence
specified by the system administrator.

1-10
Compaq 3000 Series UPS Operation and Reference Guide
This sequence might include:
■
Saving work-in-progress throughout the network.
■
Powering down non-critical devices, to extend the battery power
available to other devices.
■
After saving the necessary information, completing the orderly device
shutdown.
For more information on using Compaq Power Management Software, refer to
the Compaq Power Products Software Reference Guide section of the Power
Products Documentation CD (included with the UPS kit).
Hardware Option Cards
The 3000 Series UPS include an option slot that will accommodate one of
these hardware option cards:
■
Compaq Multi-Server UPS Card (option kit part number 123508-B21)
■
Compaq Scalable UPS Card (option kit part number 123509-B21)
■
Compaq SNMP-EN Internal Adapter (option kit part number
347225-B21)
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.

Overview
1-11
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.
Compaq SNMP-EN Internal Adapter
In a network environment, the SNMP-EN Internal Adapter provides a user
interface, allowing communication between the UPS and the server (when the
SNMP-based power management software, Compaq OnliNet Centro, is
installed). For workstations or other peripheral equipment that cannot be
interrupted by a network management system, a UPS with the SNMP-EN
Internal Adapter option installed can also provide a power management
solution.
Using the SNMP-EN Internal Adapter SNMP communication interface,
system administrators can quickly ascertain if power-related problems exist
anywhere on the network. A Compaq UPS, connected by an SNMP-EN
Internal Adapter to power management software, can virtually eliminate costly
downtime due to power outages or surges, and decrease day-to-day network
management annoyances like spontaneous rebooting, lost files and corrupted
data—issues resulting from inconsistent power.
Compaq OnliNet Centro software is a versatile application that can schedule
network component shutdowns or, in case of a utility power outage, perform
graceful, sequential shutdown of network components.
Remote Emergency Power Off (REPO) Port
The 3000 Series UPS models include a Remote Emergency Power Off
(REPO) port. The REPO feature allows the UPS to be shut down from a
remote location. To use this feature, the REPO port must be connected to a
remote, normally open switch (not supplied). When this switch is closed, the
UPS immediately disconnects power from its load segments.

1-12
Compaq 3000 Series UPS Operation and Reference Guide
To shut down the entire network in the event of an emergency, the REPO ports
of multiple UPS units can be connected to a single switch.
IMPORTANT:
The REPO port meets the requirements of NFPA Articles 645-10 and
645-11 for a Disconnecting Means.
IMPORTANT:
■
If the remote switch is closed, the REPO feature shuts down protected devices
immediately and does not utilize the orderly shutdown procedure initiated by
Compaq Power Management Software.
■
The REPO feature shuts down UPS units operating under either utility or
battery power.
■
If the UPS was operating on battery power when the remote switch was closed, no
power will be available to the devices until utility power is restored.
Warranties
$25,000 Computer Load Protection Guarantee
To back up the wide range of features offered with the UPS, Compaq provides
a three-year limited warranty. In addition, Compaq offers a $25,000 Computer
Load Protection Guarantee (provided by the original equipment manufacturer).
IMPORTANT:
The warranty card supplied with the UPS must be filled in and returned to
qualify for the $25,000 Computer Load Protection Guarantee.
The $25,000 Computer Load Protection Guarantee only applies if:
■
The UPS is plugged into a suitably grounded and wired outlet using no
extension cords, adapters, other ground wires, or other electrical
connections.
■
The UPS installation complies with all applicable electrical and safety
codes specified by the National Electrical Code (NEC).
■
The UPS is used under normal operating conditions. Users comply with

Overview
1-13
Pre-Failure Battery Warranty
The Pre-Failure Battery Warranty, standard on all Compaq Uninterruptible
Power System (UPS) units, extends the advantage of a Compaq three-year
limited warranty by applying it to the battery before it actually fails.
Specifically, the Pre-Failure Battery Warranty ensures that when customers
receive notification from Compaq Power Management Software that the
battery may fail, the battery is replaced free of charge under the warranty.
Compaq maintains the highest standards in the industry, as evidenced by the
Compaq Pre-Failure Battery Warranty. The Pre-Failure Battery Warranty is
beneficial in at least two significant ways:
■
Reduced total cost of ownership
■
Reduced downtime

Connecting to the Communications Port
The 3000 Series UPS models include a communications port for data
exchange with the host computer.
IMPORTANT:
Compaq Power Management Software, LanSafe III, and FailSafe III require
the communications port to be appropriately cabled to the host computer.
Connect the UPS/computer interface cable (supplied) from the
communications port on the UPS to the appropriate communications port on
the host computer.
CAUTION:
To avoid damaging the equipment, do not use the communications
cables (part numbers 142260-001 and 142260-002) supplied with earlier UPS
models. The UPS/computer interface cable is required to carry power and is
wired differently than earlier communications cables.
