switch:FID128:admin> chassisdisable

This command can cause disruption to multiple logical switches.

Are you sure you want to disable all chassis ports now? (yes, y, no, n): [no]y

All Fibre Channel ports on all logical switches are taken offline. If the logical switches are in

fabrics, the fabrics are reconfigured.

NOTE

After a chassisDisable, if you want to do an haFailover, you should wait at least 30 seconds.

Enabling a chassis

Enabling a chassis enables all Fibre Channel ports on all logical switches in the chassis. The

chassis is enabled by default after it is powered on and switch initialization routines have finished.

You must re-enable the chassis after making fabric-wide configuration changes or running offline

diagnostics.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the chassisEnable command.

switch:FID128:admin> chassisenable

For all logical switches in the chassis, all Fibre Channel ports that passed Power On Self Test

(POST) are enabled. If any of the logical switches have inter-switch links (ISLs) to a fabric, it joins

the fabric.

switch or platform by suddenly shutting down power and powering on again.

Powering off a Brocade switch

Use the following procedure to gracefully shut down a Brocade switch.

1. Connect to the switch and log in using an account assigned to the admin role.
