Bay19 Network switch in RCA rebooted at 06:30 April 24th

Network switch bay19 in the Chemistry Annex was rebooted at 06:30. Connectivity was interrupted for 7 minutes.


Reason :

New SIP phones being deployed in RCA where not being recognized as phones by the switch. It was noted that the top switch (Base Unit)  in the stack of two 5520's was very noisy. After reboot it appeared dead (no power) for several minutes. A clicking could be heard indicating possible power supply failure. After a few minutes it powered up.


This switch stack needs to be replaced ASAP with newer Juniper EX 3400 switches.
