SNMP Port
Four dry contacts indicating the following conditions:
"UPS ON" (Output OK)
"Battery Voltage Low"
"Input Power Loss" (Battery Operation)
"Fault Detect"
A "Shutdown" input (via opto-isolator) for remote shutdown of the UPS during AC
input fail. When the AC input recovers the UPS will automatically turn ON.
RS-232 Serial port (EIA-RS-232).
The serial port allows transmission of status and reception of User-Programmable
Options, some of which are described below:
Status: Input OK, Output OK, On Battery, Low Battery, Over-Temperature
Warning, Battery Test Passed/Failed, Load Level, Charge Level, status of all User
Programmable Options and failure diagnostic.
Commands: UPS Shutdown, UPS Standby, Initiate Battery Test, Enable/Disable
Periodic Battery Test, Enable/Disable Battle Mode, Enable/Disable Aural Alarm, Set
Input power Limit (see Note 2), Protection Reset (resets all latching protection
circuits), System Reset (forces all User Programmable Options into their default
state and resets all latching protection circuits).
For the complete set of the available Status messages and Commands, refer to the
M120BA-1A Software Interface Manual. (Available at http://www.milpower.com).
Optional, RJ-45, CAT-5 SNMP Port with Server/ Client Monitor Software.
Allows monitoring of the UPS (using MIBs). Supports user defined event-triggered
shutdown. Supports different shutdown timing for each Client in the net.
Supports delay UPS shutdown (after the Server has been shut down).
SCREENING
Each unit is subjected to a Power Burn-in of 24 hours. Additional ESS is available
upon request.
ACOUSTIC
NOISE
Less than 48dBA.
FUNGUS
Does not support fungus growth, in accordance with the guidelines of
MIL-STD-454, Requirement 4.
WEIGHT and
SIZE
140 Pounds. (88 Pounds without the Battery Pack. Add 8 pounds for M359-1-2 )
19”, 3-U, 22” deep, Rack mount or Hard mount.
Notes
1. The Neutral Grounding Link is accessible to the user and may be removed to obtain a floating output
(not recommended, may result in a safety hazard).
2. The long-term maximum loading of the UPS Output is limited by the fan’s cooling capacity. At ambient
temperature above 40C, the maximum steady-state output power should be derated to 1.5KW at
52C. For short term loading (less then 5 minutes) no derating is required.
3. High temperature for prolonged duration will shorten the battery life.
