Power Modules
- All power modules (except the 870 W
PoE power module) are hot swappable, but it is highly recommended
that you power off a switch before removing or installing a power
module in the switch to protect personal and equipment safety.
- Before replacing a power module in a switch, make sure that the
switch can be powered by the other power module after the power module
is removed. Otherwise, services on the switches will be interrupted
by a power failure when the power module is removed.
- Before powering off a switch, shut down all of its power supply
units.
- A switch can only use power modules matching its chassis model.
Using unsupported power modules will cause unexpected risks.
- If a switch has two power modules for 1+1 power redundancy and
one of them is powered off, the indicator of this power module will
not turn off immediately. This is a normal situation.
- If the total power of powered devices (PDs) connected to a PoE
switch exceeds the rated PoE power of a single power module in the
switch, the switch does not support 1+1 redundancy of the PoE power
modules. If you need to power off one power module, limit the total
power of PDs within the PoE power that one power module can provide.
