Replacing a power supply

Cabling a fiber-optic transceiver

To cable a fiber-optic transceiver, perform the following steps:
1. Before cabling a fiber-optic transceiver, it is strongly recommended that you clean the cable
2. Gently insert the two cable connectors (a tab on each connector should face upward) into the
Replacing a power supply
You can replace a power supply while the device is powered on and running. For the location of the
power supplies (AC or DC) refer to
CAUTION
If you are hot-swapping a module, power supply, or fan tray, allow a minimum of two seconds
after a module (or power supply or fan tray) has been removed before inserting a module in the
same slot.

Determining which power supply failed

To determine which power supply has failed, enter the show chassis command at any CLI
command prompt.
Brocade# show chassis
This command displays status information for the fans and power supplies, and temperature
readings for various components in the device. The power supplies are numbered in the display.
Refer to
If a power supply has failed, the display indicates "Installed (Failed)" and identifies the slot in which
the failed power supply is installed.

Setting the threshold for power supply monitoring

The power-supply monitoring threshold command monitors the power supply state, and indicates
when a power supply will shut down due to failure.
To set a threshold value for power supply monitoring, enter the following command.
Brocade(config)#power-supply monitoring threshold 3
A Power Supply will be Shutdown if it fails 3 times within an Hour
The power supply will flap three times within an hour, after which the power supply will
automatically shut down.
Syntax: [no] power-supply monitoring [threshold <decimal>]
The <decimal> variable specifies the number of flaps within an hour after which a power supply will
automatically shutdown. The threshold range is from 0 through 32. The default value is 5. A value
of 0 disables the power supply auto-shutdown on flapping.
