Installing the switch power supply

You must install at least one power supply before using the switch. ERS 4800 models support two
field replaceable internal power supplies. If supported, you can install an optional second power
supply for redundancy, load sharing, or to provide additional PoE+ power budget.
Perform the following procedure to install an internal power supply into your switch.
Note:
The switch hardware can vary. This procedure only applies to hardware models with field
replaceable power supplies.
1. If a blanking plate covers the required power supply slot, remove the blanking plate before
attempting to insert the power supply.
2. Insert each power supply into a rear power supply slot.
3. Verify that each power supply is fully seated in the slot. Secure the power supply with the
two thumb screws.
