3.3.2 Hot Swap Extraction
To extract the MCH module proceed as follows:
1. Ensure that the safety requirements indicated in Section 3.1 are observed.
2. Pull the module handle in the “Hot Swap” position.
When the module handle is in the “Hot Swap” position, the extraction process of the module is initi-
ated and the following occurs:
• The BLUE HS LED displays short blinks. When the power module IPMI controller receives the handle
opened event, it sends a command to the MCMC with a request to perform short blinks of the BLUE
HS LED.
This indicates that the MCH is waiting to be deactivated.
Once the MCH receives the permission to continue the deactivation, all used ports are disabled.
• The BLUE HS LED turns on.
The Intelligent Platform Management Controller on the power module disables the module's pay-
load power and the BLUE HS LED is turned on.
Now the module is ready to be safely extracted.
3. Pull the module handle in the “Unlocked” position.
4. Disconnect any interfacing cables that may be connected to the module.
5. Disengage the module from the backplane connector by pulling on the module handle. This may require
a considerable amount of force.
6. Using the front panel as a grip, remove the module from the chassis.
7. Dispose of the module as required.
