|Ticket Description:||Scheduled maintenance at DWDMlight node in Manno|
|Scheduled Starttime:||Scheduled Endtime:|
Problem Description:We replace the controller of our DWDMlight node at CSCS, Manno and install an extension chassis. This upgrade will give us additional functionality and allow us to use the new dual port 10GE transponders in future.
There will be an interruption of our 10GE link Manno - Lausanne. Physical redundancy remains in place all the time through Brig - Martigny at Gigabit speed. In order to keep up 10GE connectivity to CSCS, we temporarily prefer the path through Zürich, however.
Affected:From 2009-06-10 11:00 until 2009-06-10 12:00
Impact: no impact (traffic temp. rerouted)
normal traffic routing restored
New shelf installed, modules swapped, all active parts now managed by new controller. 10GE link CSCS - EPFL is up again.
traffic diversion verified, node down
