Power supplies

The Edge 3000 Series ships with two AC power supplies, depending on the configuration. Airflow is from the I/O panel to the PSU.

Two PSUs are required for full redundancy, but the platform can operate with a single PSU.

The PSUs are field replaceable. When running with full redundancy—two power supplies installed and running—you can remove and

replace one PSU without disrupting traffic.

CAUTION: To prevent electrical shock, ensure that the platform is grounded properly. If you do not ground your

equipment correctly, excessive emissions may result. Use a qualified electrician to ensure that the power cables meet

your local electrical requirements.

NOTE: Connect the power supply to the appropriate branch circuit protection as defined by your local electrical codes.

Verify that the remote power source complies with the platform input power specifications.

NOTE: If you use a single PSU, install a blank plate in the other PSU slot. Use power supply 2 (PSU2) as the blank-plate

slot. You do not need tools to install the blank plate.

NOTE: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap

when handling the platform and components.

AC power supply installation

NOTE:

The PSU slides into the slot smoothly. Do not force a PSU into a slot as this action may damage the PSU or the

platform.

NOTE: Ensure that you correctly install the PSU. When you install the PSU correctly, the power connector is on the left

side of the PSU.
