Verifying The New Modules; Installing The Remote Power Cycling Feature Control Wires (Optional) - Cisco Line Card 4500 E-Series Installation Manual

Chapter 4 Removal and Replacement Procedures
Step 15 If you are installing a clock module, secure the module to the backplane using the two screws from the
earlier removal.
Step 16 Reinstall the supervisor engines and the switching modules in their previous slots.
Reconnect all of the network interface cables to the switching modules.
Step 17
Step 18 Restore power to the switch.

Verifying the New Modules

After the switch is reassembled and power is restored, connect a terminal to the supervisor engine and
monitor the boot process. Look for the following messages (or any others), which may indicate a
problem with the replaced modules:
00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 3 is not present
00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 4 is not present
00:00:20: %C4K_SUPERVISOR-2-MUXBUFFERNOTPRESENT: Mux buffer (WS-X4K-MUX) 7 is not present
The above messages (either at startup or output from a show logging command) indicate that the
mux-buffer is not present in slots 3, 4 and 7. You need to reinsert and reseat the modules in those slots.
If the switch has already started up, you may also verify the correct function of the new modules with
the show logging command.
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 6000 W AC-input power supply.
Several vendors make remote power cycling relay controller boxes that can be used to power cycle the
Catalyst 4500 E-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 an RS-232 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 four-position
terminal block located on the front of the 6000 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 6000 W
Note
AC-input power supply.
