5548 Remove Switch from Stack
I have a 3 switch stack of 5548's. My needs have changed and no long need the third switch in the stack, so I wanted to remove it.
I removed spanning-tree on all the ports on switch 3. Then I moved around the HDMI interconnect cables so that only switch 1 and switch 2 are interconnected. The web interface no longer shows the ports from switch 3 (Good), but the console shows the configuration for the switch 3 port when I do "show run" or "show startup"(Bad). More importantly, the console stalls when I do "show interfaces status" as it walks through the ports and gets to what was switch 3.
How do I remove all the switch 3 interfaces from the config?

Tried reload:
stack22# reload slot 3
Unit does not exist over the stack!
The firmware was a little old (4.1.0.16), so I did update it. But that did not help.

I know it sounds odd, but the ports are still in the running and startup config after a reload:
stack22# terminal datadump
stack22# show run
.
.
interface gigabitethernet3/0/1
switchport access vlan none
!
interface gigabitethernet3/0/2
switchport access vlan none
!
interface gigabitethernet3/0/3
switchport access vlan none
!
.
.
Only the second TenGigabit interface is missing (we never configured it).
I have cleared all the descriptions and configs from those ports. I can't figure out how to remove the "switchport access vlan none" - might that be why those ports won't disappear?

That was actually on of the first things I tried. But that was before I cleared out all the other configs and several reloads ago...
stack22# conf
stack22(config)# interface tengigabitethernet 3/0/1
stack22(config-if)# no switchport access vlan
stack22(config-if)# exit
stack22(config)# exit
stack22# show run interface tengigabitethernet 3/0/1
interface tengigabitethernet3/0/1
switchport access vlan none
!
stack22# conf
stack22(config)# interface gigabitethernet 3/0/3
stack22(config-if)# no switchport access vlan
stack22(config-if)# exit
stack22(config)# exit
stack22# show run interface gigabitethernet 3/0/3
interface gigabitethernet3/0/3
switchport access vlan none
!
Thanks for your help so far!
