Configuration and Operation

Quick Test

After installing the PDU and connecting
equipment, you may test the Automatic
Transfer Switch function by temporarily
shutting down the UPS system
connected to the Primary AC input.
When the Primary input UPS is no longer
supplying AC power, the PDU will switch
from the Primary input to the Secondary
input, and the Secondary input LED will
illuminate. When the Primary input UPS
has been restarted and resumes
supplying AC power, the PDU will switch
back to the Primary input.
Note: The primary and secondary inputs must be
connected to separate sources of utility power. The
automatic transfer switch function will be
compromised if the primary and secondary inputs
are connected to the same utility power source. Do
not perform a test with equipment that must remain
in productive operation. Any test procedure must
prepare for the contingency that the equipment may
lose power. Do not test the PDU by detaching power
cords which are connected to live power sources, as
this eliminates the connection to ground and places
your equipment at risk.

Remote Monitoring and Control

The PDU provides remote monitoring, outlet control and more via Web browser, telnet
and SNMP-based Network Management Systems. For more information about
configuration and operation of the PDU via the PowerAlert Web browser interface,
refer to the SNMPWEBCARD User's Guide, included on the CD-ROM bundled with
the PDU.
Load "Ramping" on Startup: All models arrive from the factory programmed so
that, when first powered up, their outlets turn on in sequential order at intervals of
approximately 250 ms. This prevents circuit overloads by staggering the startup of
multiple devices. Models PDUMH30HVATNET and PDUMH30ATNET support user-
programmable startup of outlets, in any order or time interval. This ensures that
network items are turned on in the proper sequence, with the appropriate delay, so
that network items are reliably discovered on startup.
Programmable Load "Shedding" During a Power Failure: In the event that the
primary power source fails and the PDU is relying on the secondary power source,
load shedding allows you to program the shutoff of specific outlets at timed intervals.
This enables you to turn off less critical loads (monitors, for example) to maximize the
UPS runtime for the most critical items.
