An undeclared port is untagged VLAN 1, which has no DHCP and no route, so a device cabled to one looks dead. Declare the port before cabling a new device.
Physical #
- Console: there is no console port. Recovery is a factory reset, then a laptop on the switch’s default subnet; see Access Switch console recovery.
Firmware #
Hardware revision 1.20 (a unit labeled V1.26 takes the same firmware). It holds two firmware images: the running version and a rollback. Both are in the Software Catalog.
