Lightning damage to networking components

Click thumbnails for a larger view.

The evening I left for Cambridge England, we had a storm in Plymouth, and lightning struck something in the area of my house. I suspect it hit the cable company's box out near the street since my neighbor lost his cable TV service at the same time.
I think that this is the path of the damage:
1) Entered at pillar near street. Cable end blasted.
2) Up the cable, and entered the modem. Modem blasted.
3) Out the ethernet connector into the WAN port on the router/switch. Switch blasted.
4) Out a connector and up to the Dell laptop cradle. Interface not working.
5) Out a connector and into the Sun Ultra-60. Interface not working.
6) Out a connector and into the Brother laser printer. Interface might not be working
7) Out a connector, outside, downstairs and into uplink port on 4-switch. Switch blasted.
8) Out a connector and into a DEC Alpha 4-processor server. Interface might not be working
