I thought the recent software release of 5.1.3.1 and 4.1.8.3 for the Ethernet Routing Switch 8600 was very odd in that they only included a single fix (wi00564790). Well it seems there’s now some additional information regarding the issue. Avaya has released a technical bulletin documenting an issue with the new version of the 8692SF that can impact the CPU utilization of the switch. If you have one of the newer 8692SFs (you can identify them from the original 8692SF by the description below) then you should most definitely upgrade to 5.1.3.1 or 4.1.8.5 or 7.0.0.2 (soon to be released).
The new re-spin version module can be identified by the PCMCIA card slot now having front panel artwork that shows “PC Card” while older versions of the module show “PCMCIA”. Additionally, the new version of the hardware can be identified via the Hardware Revision 52.
Otherwise there doesn’t appear to be any need to upgrade your ERS8600 to this specific release.
Cheers!
