Removing a multiplexer expansion module
To remove a multiplexer expansion module or filler, complete the following steps.
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 31.
2. Make sure the FRR LED on the multiplexer expansion module is lit. This LED
must be lit before removing the module. For more information see “BladeCenter
HT components, controls, and LEDs” on page 14.

or a filler into the module bay.
5. If you are instructed to return the multiplexer expansion module, follow all
