Hi CPjitservices
I too like the Nortel 5510, I look after 32 5510-48T in or DC and DR centers split in to stacks, I have 1 5510-24t, could you tell me what firmware level you are running ? I want to add the 24 port in to a stack of 48 ports, but I think the firmware is too old, The 48 port units are at 6.1.28.028, But unless you have a support contract with Nortel ( Avaya ) you can not access the latest fw,
The other thing I like is that is you have a stack and upgrade the Base, the rest of the stack gets it too, so now one by one upgrades
