On-Line UPS
User Manual
Models: UPS-1500-OL, UPS-2000-OL, UPS-3000-OL
SX-BDL-1500, SX-BDL-2000
SNMP Communications Option
The UPS provides an intelligent slot for internal or external network card. This special intelligent network card
can be compatible with popular software and hardware found on the web and in operating systems. It can
support operating systems such as HP Open View, IBM Netview, SUN Netmanager, etc. This enables the UPS
to provide instant UPS and power information over the network. Please contact your reseller for additional
details.

:
The UPS can be monitored through the RS232 interface or the SNMP card, but only one way at a time.
The user can choose RS232 or SNMP communications through the communications switch on the rear
panel of the UPS. RS232 is chosen if the switch is depressed to the RS232 position, and SNMP is
chosen if the switch is depressed to the SNMP position. When there are two or more monitored pieces
of equipment, the ground of each piece of equipment should be shared. The SNMP card is configured
as DHCP by default IP setting.
Remote Emergency Power Off (REPO) Port
A customer supplied switch located remotely can be used to close the REPO connection and allows the UPS
output receptacles to be switched off. Since the REPO shuts down the equipment immediately, orderly
shutdown procedures are not followed by any power management software. The UPS will have to be manually
restarted in order to regain power to the outlets on the UPS.
6. Determining the Power Requirements of your Equipment
A.
Make sure the total Volt-Amp (VA) requirements of your connected equipment does not exceed the
maximum VA rating for the UPS. The maximum VA ratings are shown in the Specifications section of this
document.
B.
Ensure that the equipment plugged into the battery-powered outlets does not exceed the UPS rated
capacity. If UPS rated capacities are exceeded, an overload condition may occur and cause the UPS to shut
down and trip the circuit breaker.
C.
If the power requirements of your equipment are listed in values other than Volt-Amps (VA), convert Watts
(W) or Amps (A) into VA by doing the calculations below. Note: The equation below only calculates the
maximum amount of VA that the equipment can use, not what is typically used by the equipment at any
given time. Users should expect usage requirements to be approximately 60% of the value to estimate
power requirements:
Watts (W) x 1.43 = _____ VA or _____ Amps (A) x 120 = _____ VA
Add the totals for all of the equipment and multiply this total by 0.65 to calculate actual power requirements.
N
OTE
: Many factors can affect the amount of power that your computer system will require. The total load
that you will be placing on the battery-powered outlets should not exceed 85% of the UPS capacity.
