2.5 Power Supply Modules
The power supply modules are hot-swappable power supply units (PSUs) for the switch.
You can install up to two PSUs. The PSUs operate in a load-sharing mode and provides 1+1
redundancy.
(Figure 2-7: Power Supply Unit)
NOTE:
1+1 redundancy is a system where a switch power supply is backed up by
another switch power supply in a load-sharing mode. If one power supply fails,
the other power supply takes over the full load of the switch.
WARNING:
• The switch includes plug-in power supply and fan tray modules that are
installed into its chassis. All modules must have a front-to-back airflow
direction, or back-to-front airflow direction.
• Risk of explosion if battery is replaced by an incorrect type. Dispose of used
batteries according to the instructions.
• Remove the power cable from the module prior to removing the module
itself. Power cable must not be connected prior to insertion in the chassis or
equivalent.
