Powering Port Blades Off And On; Disabling And Enabling Port Blades; Fr4-18I Blade Exceptions - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

Powering port blades off and on

All blades are powered on by default when the switch chassis is powered on. Blades cannot be powered
off when POST or AP initialization is in progress.
NOTE: In the DC Director, the core blades in slots 5 and 8 cannot be powered off with the CLI interface.
You must manually power off the blades by unseating the blade from its mounting or removing the power
from chassis.
To power off a port blade:
1. Connect to the switch and log in as admin.
2. Enter the slotPowerOff command with the slot number of the port blade you want to power off.
switch:admin> slotpoweroff 3
Slot 3 is being powered off
switch:admin>
To power on a port blade:
1. Connect to the switch and log in as admin.
2. Enter the slotPowerOn command with the slot number of the port blade you want to power on.
switch:admin> slotpoweron 3
Powering on slot 3
switch:admin>

Disabling and enabling port blades

Port blades are enabled by default. In some cases, you will need to disable a port blade to perform
diagnostics. When diagnostics are executed manually (from the Fabric OS command line), many
commands require the port blade to be disabled. This ensures that diagnostic activity does not interfere
with normal fabric traffic.
To disable a port blade:
1. Connect to the switch and log in as admin.
2. Enter the bladeDisable command with the slot number of the port blade you want to disable.
switch:admin> bladedisable 3
Slot 3 is being disabled
To enable a port blade:
1. Connect to the switch and log in as admin.
2. Enter the bladeEnable command with the slot number of the port blade you want to enable.
switch:admin> bladeenable 3
Slot 3 is being enabled
FR4- 1 8i blade exceptions
You may wish to persistently disable FR4- 1 8i blade ports that are not configured so they cannot join the
fabric when the following scenarios apply:
• The FR4- 1 8i blade ships with FOS 6.0.0b pre-installed. If this blade is inserted into a chassis running a
version of FOS that is different than the revision level currently on the blade, the blade firmware will be
upgraded or downgraded to match the firmware revision on the chassis.
• You have inserted the FR4- 1 8i blade into a slot that was previously empty or contained an FC4-48,
FC4-32, FC8-48, FC8-32, FC4- 1 6, FC10-6, or FC4- 1 6IP.
• You have turned on the power of the chassis and the FR4- 1 8i blade in that slot was not active prior to
the power-on.
If the FR4- 1 8i blade is operational and the Director is rebooted, then after the successful bootup of the
system the blade continues operations using the previous configurations.
