I purchased a used Cisco 2940 switch a while back for my lab for $50 from EBAY.
I'm sure you've heard me mention this switch in the past and I have several of them in the lab.
I really like these Cisco switches for the following reasons:
- uses Cisco IOS so I can telnet, etc
- nice compact size for when I need to take it along
- fanless
- can span or mirror ports
- has 1 Gb copper uplink port and 8 X 10/100 Mb ports
- SNMP support for the network management applications that I'm testing
While using the switch, I noticed the power would intermittently cut out. At first I thought, "What do expect for a used switch" and would simply jiggle the power cable to get it going again.
One day I got fed up playing the jiggle game and had some time to kill during a conference call, so I took the switch apart.
To my surprise it looked like a simple case of a cold solder. After warming up the old soldering iron, I re-soldered the 3 power pins and viola, good as new.
