UPS ACCESSORIES
When and why you’ll need them
There are several reasons why having just a UPS system alone may not
meet all of your requirements. Accessories like SNMP cards, additional
batteries and switches will complement your UPS the same way a
mouse, keyboard and monitor typically complement a CPU, Since online
UPS models are usually used with sensitive equipment, troubleshooting
or maintenance usually needs to be done without having to shutdown
or turn off the actual equipment. In such situations, accessories like
Automatic Transfer Switches and Maintenance Bypass Switches may be
required to switch the equipment’s power source to other backup units or
to the mains power supply.
UPS usually backs up critical loads such as
the power source tied to an ATM or sensitive
medical apparatus. Therefore, it’s essential that
the performance of the UPS be monitored, but
yet a true waste of manpower to have someone
stationed in the UPS room just to look over the
system.
An item like a Simple Network Management Protocol (SNMP) card can
be utilised in such cases where the company would like to monitor their
UPS performance. An SNMP is a standardised communication system
used on Local and Wide Networks (LANs/ WANs) to monitor and control
hardware systems connected to it via Transmission Control Protocol /
Internet Protocol (TCP/IP) connections. The SNMP uses hardware specific
Management Information Bases (MIBs) to collect information from polled
IP connections. These can be viewed on a Network Management Station
(NMS) or high performance workstation with a fast CPU and extensive
hard disk capacity running specific monitoring and controlling software.
