Resetting a switch

Resetting a switch reboots the switch using the switch configuration parameters last saved in permanent 

memory on the switch. Depending on the reset type, a switch reset may or may not include a Power On 

Self Test (POST) or it may or may not disrupt traffic. 

 describes the types of switch resets.

During a hotreset operation, fabric services will be unavailable for a short period (30—75 seconds 

depending on switch model). Verify all administrative changes to the fabric (if any) are complete before 

performing an Non-Disruptive Code Load and Activation (NDCLA). When upgrading firmware across a 

fabric using non-disruptive activation, upgrade one switch at a time and allow 75 seconds between 

switches.

Changes to the fabric may disrupt the NDCLA process. More than one McDATA Web Server 

session will disrupt the NDCLA process.

Common administrative operations that change the fabric include:

Zoning modifications

Adding, moving or removing devices attached to the switch fabric — this includes powering up or 

powering down attached devices

Adding, moving or removing ISLs or other connections

After an NDCLA operation is complete, management connections must be re-initiated:

The McDATA Web Server session will re-connect automatically

Telnet sessions must be restarted manually

Applicable code versions:

Future switch code releases will be upgraded non-disruptively unless specifically indicated in its 

associated release notes

An NDCLA operation to previous switch code releases is not supported

To reset a switch using McDATA Web Server, perform the following procedure:

Select the switch to be reset and open the faceplate display.

Select Switch > Reset Switch:
• Select Hot Reset to perform a hot reset
• Select Reset to perform a standard reset
• Select Hard Reset to perform a hard reset

Switch resets

Hot Reset

Resets a switch without a POST. This reset activates the pending 

firmware, but does not disrupt switch traffic. If errors are detected on 

a port during a hot reset, the port is reset automatically.

Reset without POST Resets a switch without a POST. This reset activates the pending 

firmware and it is disruptive to switch traffic. 

Hard Reset

Resets a switch with a POST. This reset activates the pending 

firmware and it is disruptive to switch traffic.
