Replacing a switch and reusing its configuration
If a remote switch that is configured by WLAN Management Software fails, you can install a new switch in its
place and use WLAN Management Software to configure the switch with the replaced switch’s configuration.

This method of switch replacement requires preconfiguration of an auto-config setting by the network admin-

remote office.
Remote switch replacement is disabled by default but can be enabled on a global basis in the network plan.
Requirements
This method of switch replacement works only under the following conditions:
•
The new switch must be the same model as the one being replaced.
•
The new switch must run the same major WSS Software version (for example, 4.1.x) as the one being
replaced.
replaced.
•
For models other than the 2350, the new switch must be pre-staged by a network administrator. (See
.)
•
The new switch must send its configuration request to WLAN Management Software from the same IP
subnet as the management address of the switch being replaced. WLAN Management Software will give
the new switch the same IP address as the old switch.

the new switch the same IP address as the old switch.
•
The new switch must be the only WSS on the subnet.
How Switch Replacement Works

A network administrator enables the Auto-Config IP Subnet Matching option in WLAN
Management Software. (This option is on the WLAN Management Software Services Setup
dialog.)

Someone at the remote office physically unplugs the failed switch and plugs in a new,

The person at the remote office powers on the new switch.
If the switch is a 2350, the person at the remote office also inserts a paperclip or similar object
into the 2350’s factory reset hole to press the factory reset switch. Normally, the factory reset
LED (the right LED above port 1) remains solidly lit for 3 seconds after power on. However,
when the factory reset switch is pressed, the LED flashes for 3 seconds instead.

This feature applies only when the wireless switch being replaced is the only
wireless switch in the network. (Also see
