Starting Up the Switch
Before you can turn on the switch, you must ensure the following:
• The switch has enough power supplies to output the amount of wattage that is required for all the modules

that are installed in the switch. Depending on the power mode that you use for the switch, consider the
following:
• For combined power mode (no power redundancy), there must be enough power supplies to power
all the modules in the chassis. No extra power supplies are needed for redundancy.
• For n+1 redundancy mode, there must be enough power supplies to power all the modules in the
chassis. And there must be one extra power supply to provide redundancy if one power supply goes
down or is replaced. The maximum number of power supplies that are needed is the number that is
used for combined power mode plus one (n+1) for redundancy.
• For n+n redundancy mode, there must be two equal sets of power supplies. Each of which can power
all the modules in the chassis and each set is connected to a separate power source. If one power
source goes down, the power supplies connected to the other power source can power the switch.
The maximum number of power supplies is the number of power supplies that are required for
combined power plus the same number of power supplies (n+n) for redundancy.
DC power supplies have two power feeds, each with a positive (+) wire
and a negative (-) wire. For simpler routing of power cables, you connect
both feeds to the same power source. Alternatively, you can connect each
feed to a separate power source but that makes the routing of power cables
more complicated.

power cables for one power source along the left side of the chassis. Route the power cables for the other
power source along the right side of the chassis. The power cables on the left side connect to power
supplies in the far left power supply slots. The power cables on the right side connect to power supplies
in the far right power supply slots. If you are not filling all the power supply slots, fill the slots on the
sides for now and leave the middle slots open. Cover each open slot with a power supply slot blank to
preserve the designed airflow, until you add more power supplies.
