Cisco 8500 - Connect DC Power to the Chassis

Note
These switches are designed to boot up in less than 30 minutes, provided the neighboring devices are in full
operational state.
Connect DC Power to the Chassis
The chassis relies on the protective devices in the building installation to protect against short circuit,
overcurrent, and ground faults. Ensure that the protective devices comply with local and national electrical
codes.
Caution
We recommend that you occupy only the left slot of the rear power supply slots of the fixed port switches
with power supply. In the right slot you must install the blank power supply. This recommendation ensures
that the system airflow is not impacted adversely, which may then result in the overheating of the switch and
its components.
Note
Procedure
Step 1 Verify that the correct fuse panel is installed in the top mounting space.
Step 2 Ensure that the DC circuit is powered down (either breaker turned off or fuse pulled) and proper lockout tag
out procedures are followed. Use the cable supplied with the power supply. You can purchase power supply
cord separately from Cisco.
Step 3 Dress the power according to local practice.
Step 4 Connect the office battery and return cables according to the fuse panel engineering specifications.
Step 5 Insert the DC connector into the DC receptacle on the power supply.
