Some of my hubs and switches are hissing (Sort of air sound not screaming). Since they are fanless I was curious. Opened one up and saw :

The two caps in the foreground are Gloria 6.3V 1500mf which appear to have swelling at the top and some slight discharge. :cry:
The caps in the background are GAE LESR 50V 1000mf. The small caps are Wendel 47mf 16V. Those appear to be fine.
Apart from the visual indications and the hissing sound the hubs are operating fine. I have 4 of these units grrrrr, purchased Feb 2000. Probably will get 1 24 port professional switch instead as it is time for more upgrading (will have to do some rewiring though). Any recommendations?
