Resetting a switch

Resetting a switch reboots the switch using the configuration parameters in memory. Depending on the
reset type, a switch reset may or may not include a Power On Self Test (POST) and/or may or may not
disrupt traffic.
During a Hot Reset operation, fabric services will be unavailable for a short period (30—75 seconds,
depending on switch model). Verify that all administrative changes to the fabric (if any) are complete
before performing a Nondisruptive 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.
Common administrative operations that change the fabric include:
• Zoning modifications
