Terminal Block
The terminal block has three contacts labeled 1, 2, and 3. Two control wires from an external relay
controller box attach to either positions 1 and 2 or positions 2 and 3. Positions 1 and 2 are used when the
relay controller box contains a normally-open (NO) type of relay. Positions 2 and 3 are used when the
relay controller box contains a normally-closed (NC) type of relay.
Relay Controller Box Switch
The relay controller box switch, located next to the terminal block, allows you to match the power supply
power control signal’s active state with the type of relay contained in the external relay controller box
(either a normally-open type of relay or a normally-closed type of relay).
Ferrite Bead
A plastic bag containing one ferrite bead and two 4-inch plastic ties is included with the 8700 W power
supply AC power cords. The ferrite bead is a passive device that limits high-frequency interference on
interface and control cables, and it is only required when you install the remote power cycling feature
that is supported by the 8700 Watt power supply. The ferrite bead is installed on the two control wires
that come from the relay controller box to the terminal block on the 8700 W power supply. The ferrite
bead should be installed as close as possible to the power supply terminal block for the bead to be
effective. You do not need the ferrite bead for 8700 Watt power supply installations that do not include
the remote power cycling feature. If you need to install the ferrite bead, refer to “Installing the Ferrite
Bead” procedure on page 4-77.
Remote Power Cycling Operation
This feature allows you to remotely power cycle the Catalyst 6500 series switch using any appropriate
third-party relay controller. This eliminates the need for you to have access to the supervisor engine
console or CLI to control power cycling. Table A-23 lists the relay controller box relay type, the
corresponding power supply terminal block positions, and a description of the power cycling operation.
