We're installing a Cisco 2602I based wireless solution onto a B5 three switch stack and some of the switch ports are refusing to come up when an access point is plugged into them. Checking the inlinepower status shows that the switch is providing ~4W of power but that the link is down. Moving the access points to other ports on the switch can allow them to come up, but this can take between 5 and 30 seconds before the link lights come up.
The cabling and patch leads (Systemax) have been checked with a Fluke meter and passed as OK.
All ports are configured identically.
On switch 1, port GE.1.41 refused to come up, but 1.42 to 1.44 all have identical access points attached and are all up and running at 1Gb.
I'm not too familiar with the Enterasys range, so would be interested to know what sort od debugging commands could be used to detect why the switch is behaving in this manner.
