Take a look at this video, which features the Catalyst 2960 products range. Notice the 2960PD-8TT-L, which is a little gem; I can imagine many circumstances when this could be used. The switch receives it’s power via PoE.
Q. What is the Cisco Catalyst 2960PD-8TT-L compact switch?
A. The Cisco® Catalyst® 2960PD-8TT-L switch has eight 10/100 Mbps ports and receives power over the Gig uplink port from an upstream power over Ethernet (PoE) switch.

The check_ups plugin was created to facilitate monitoring of a number of UPS vendor products. To use the plugin you will need to install UPSD daemon distributed with Russel Kroll’s Smart UPS Tools on the remote host. (See the REQUIREMENTS at the end of this post).
