5.4 Expansion, replacement and removal of power supplies
This section describes the procedures to expand, replace and remove the power supplies
in the redundant power models.
Power supplies can be added, replaced, and removed while the switch is on.
5.4.1 Redundant power model (AX3630S, AX3640S)
After a power supply unit is removed, mount a fan unit. Otherwise, the following
problems might occur:
An increase in the temperature inside the switch might cause a failure.
The components might cause an injury.
Foreign matter inside the switch might cause a failure.
Waves emitted by the Switch might affect other devices, or waves emitted by
other devices might affect the Switch and cause a malfunction.
CAUTION
When a power supply unit is replaced while the switch is still on, do not leave the
switch on for more than three minutes without a power supply unit. Otherwise, a
failure might occur due to increasing temperatures inside the device.
NOTE
When using only one power supply unit, insert the power supply unit into power
supply unit slot 1 and the fan unit to power supply unit slot 2.
To install the fan unit, see
NOTE
The figures below show the power supply unit for AC power supplies. The same
procedures are applicable to the power supply unit for DC power supplies.
(1) Removing
[Step 1]
Turn off the power supply unit to be replaced.
[Step 2]
Disconnect the power cable from the power supply unit to be replaced.
For the extension or replacement of a power supply unit, disconnect the power
cable from the power supply unit to be replaced. When the power cable is
connected, part of the circuit is energized even though the power switch is off.
Therefore, the extension or replacement of the power supply unit with the power
cable connected can cause a fire or an electric shock.
NOTE
To change the power supply unit from a DC power supply unit to an AC power
supply unit, disconnect the power cable and then the ground cable. Store the
removed ground cable securely.
