To enable a shutdown on a power supply, enter the following command:
NetIron#power-off power-supply 3
This will Shutdown The Power Supply # 3
Are you sure? (enter 'y' or 'n'): y
ERROR: Power Supply # 3 is the Last Available in the system and will not be shutdown.
To force the shutdown, please use keyword "forced"
Syntax:
power-off power-supply [forced] <decimal>
The power-supply option allows you to shutdown a power supply.
The <decimal> variable specifies a power supply index number.
The forced option forces the last power supply available in the system to shutdown.The CLI will not shutdown the
last power supply unless the forced option is used.
Powering on the Power Supply through the CLI
The
power-on power-supply
command allows you turn on a power supply that has been shutdown.
A power supply will shutdown due to flapping, or if a shutdown is enabled manually using the
power-off power-
supply
command. See “Enabling a Power Supply Shutdown” on page 6-11.
To turn on a power supply that is shutdown, enter the following command:
NetIron#power-on power-supply 1
AC Power Supply 1 is OK
The output example displays the status for power supply 1 as OK.
NOTE:
If a power supply is shutdown, this will cause the Interface Module to power off. There will not be enough
power remaining in the system.
Syntax:
power-on [power-supply <decimal>]
The <decimal> variable specifies a power supply index number.
Replacing a Power Supply
To replace a power supply, you need the following:
•
A new power supply (AC or DC), which you can order from Foundry
•
A small flathead or Phillips screwdriver (NetIron MLX-4 only)
WARNING:
The power supplies are hot swappable, which means they can be removed and replaced while the
NetIron MLX Series chassis is powered on and running. However, Foundry recommends that you disconnect the
power supply from its power source before removing and replacing the supply. The NetIron MLX Series chassis
can be running while a power supply is being removed and replaced, but the power supply itself should not be
connected to a power source. Otherwise, you could be injured or the power supply or other parts of the device
could be damaged.
WARNING:
The front panel of a power supply includes a handle that locks the power supply in the chassis. This
handle is a locking mechanism only and should not be used to lift and carry the power supply. You may sustain
physical injury or harm if you attempt to lift and carry a power supply using the locking handle.
To replace a power supply, do the following:
1.
Disconnect the power supply from its power source.
2.
Disconnect the power cables from the power supply.
3.
In the NetIron MLX-4, use the screwdriver to loosen the two screws on both sides of the power supply front
panel. Then pull the ejectors forward until the power supply is pulled from its connection to the backplane.
