Installing the power supply
You must install at least one power supply before using the switch. Some ERS 4000 Series
models can support an optional second power supply for redundancy and load sharing.
To install the power supplies into your switch, perform the following procedure.
1. Insert each power supply into a rear power supply slot. If a blanking plate covers
the required power supply slot, remove the plate before inserting the power
supply.
2. Verify that each power supply is fully seated in the slot. Secure the power supply
with the two thumb screws.
3. Once you have installed at least one power supply, you can connect the power cord
to a power outlet.
