Well that's on the "tough"switch, not the suppressor. Surge suppressors 
clamp to ground. That's what they do. Shorts can happen for a variety of 
other reasons anyway and the power supplying device should be able to 
deal with that too.

Stuff I've shorted that still works:

* Cisco Cat6500 POE enabled linecards (port fault shutdown)
* PowerDsine managed midspans (port fault shutdown)
* PowerDsine passive (overcurrent cycling)
* Packetflux passive (blew inline fuse)
* UBNT single power injectors (overcurrent cycling)

Once I accidentally connected a low voltage surge protector to a POE 
port on the Cisco. The result was it kept clamping to ground every time 
the port tried to power up. The switch spewed port fault traps for a 
minute before I realized the suppressor was suppressing the POE voltage 
per its ratings (7 volts?) but it didn't damage the POE port. I've also 
had a few failed UBNT Instant 802.3af adapters short out and do the same 
thing without the POE supply being damaged other than tripping whatever 
its fault protection mode was.
