Never had problems with them so far. Just be careful to correctly
position the cards in their rails. Also, visually inspect the
connectors before inserting them in, and if you have the slightest
doubt about a pin being bent or whatnot, try the card in a spare
chassis first. We threw away (well, cisco did) one GSR backplane and 2
CRS chassis because the term "Hot Insertion" became literal: magic
smoke from the backplane is not good. 

Ah, and of course check your power budget before adding new cards too. 
(show power and related commands on 7600)
