Networking

• Please keep an updated copy of this page printed out and posted in the server room, so there is access to documentation even if the network / internet is down
• Also see IT Policies
• We have many people working with the equipment, remember to attach or tie down anything that could get unplugged/fall/etc. We twice lost internet - first time the router fell and power switch got pressed, second time the power plug was pulled out of main internet switch.
• this page is finally being updated for Sksp2, old page is at Networking/Old
