IST staff will replace the media converter at BWRC to try to solve the outgoing packet loss issue. It should take about 10-15 mins. BWRC outgoing network traffic will be affected. BWRC internal network traffic will still remain working. We will schedule about 1 hour maintenance window in case something unexpected occur. If you have any question, please send email to networks@eecs.

EMERGENCY SCHED MAINTENANCE potentially campus-wide impact thu 2 feb 2012 1500 – 1600

Equipment: inr-002 campus border router Location: potentially campus-wide impact Date: thu 2 feb 2012 Start: 1500 End: 1600

Description: an FPC (interface module) in inr-002, one of UCB’s two border routers connecting to the CalREN networks, has failed and must be replaced. i’m scheduling an emergency maintenance window 1500-1600 tomorrow, thu 2 feb 2012, for swapping out the failed FPC with a replacement unit. (this assumes the replacement FPC will arrive early enough tomorrow for the scheduled maintenance window.)

FPCs are hot-swappable (and the one currently in the router is already offline), so i don’t anticipate any disruption to campus’s external connectivity. however, to be doubly sure, i will have previously moved all external traffic off this router and onto inr-001, the redundant border router.
