Installing the Remote Power Cycling Feature Control Wires (Optional)

Checking the Air Filter

Once you have installed the optional air filter assembly on the Catalyst 6509-NEB-A or
Catalyst 6509-V-E switch chassis, you need to periodically check the air filter for damage and
cleanliness. We recommend that you perform a visual inspection of the filter at least once a month, or
more often in dusty environments. Replace the filter if appears clogged with dust, or you have detected
an increase in the chassis internal operating temperature. Failure to periodically check the filter can
result in restricted airflow through the filter leading to chassis overheating and degraded EMI
performance.
Damage to the air filter can restrict the airflow, cause overheating in the switch, and degrade EMI

performance. Be careful handling the air filter when installing or cleaning the filter. We recommend that
you inspect the filter once a month for signs of damage or change the air filters every three months, or
more often in dusty environments.
Installing the Remote Power Cycling Feature Control Wires

(Optional)

The remote power cycling feature allows you to power down and power up a switch chassis through the
network rather than being physically present to turn the power supply power switch off and on. The
remote power cycling feature is only available on the 8700 W AC-input power supply.
Several vendors make remote power cycling relay controller boxes that can be used to power cycle the
Catalyst 6500 series switch chassis. Most of these relay controller boxes have the capability of
controlling multiple power supplies. The relay controller boxes have a network interface that allows the
user to remotely access the relay controller box and toggle a built-in relay. The built-in relay can be
either a normally open (NO) type or a normally closed (NC) type of relay. We strongly recommend that
you purchase a relay controller box that uses a NO relay. The relay controller box is installed near the
switch chassis and is attached to the network. Two control wires extend from the relay controller box to
a three-position terminal block located on the front of the 8700 W power supply. A signal from the relay
controller box travels through the control wires to toggle the power supply on or off.
This section only describes how to install the remote power cycling feature control wires; relay
controller box installation instructions should be provided by the maker of the relay controller box.
The remote power cycling feature and this installation procedure are applicable only for the 8700 W
