Removing a 2.5-Gbps transponder module from the Cisco ONS 15540 ESPx
causes bit rate errors on other 2.5-Gbps transponder modules in the 2.5-Gbps line
card motherboard. Although these errors do not affect system traffic, you can
avoid them using the following privileged EXEC command before removing the
transponder module:
Command
hw-module subslot slot/subslot
power off
The hw-module subslot power command is only supported on modules installed
in 2.5-Gbps line card motherboards with hardware version 5.1, or later, and with
LRC (line card redundancy controller) functional image version 2.72, or later.
To determine the functional image and hardware versions on your system, use the
show hardware detail command.
Wait 60 seconds after removing a 2.5-Gbps transponder module before inserting
a 2.5-Gbps transponder module into the same subcard position in the 2.5-Gbps
line card motherboard.
Example
The following example shows how to turn off the power to a 2.5-Gbps transponder
module before removing it:
Switch# hw-module subslot 8/1 power off
Warning: Power OFF subcard 8/1.
Switch#
Purpose
Turns off the power to a 2.5-Gbps
transponder module.
