Note –
As long as the switch is removed from the slot, and the system is running
with only the single remaining switch, you do not have redundancy for that
component. Both switches must be installed and running to have redundancy for
that component.
1.8.1.2 Removing a Rear Transition Module for a Switch
1. Remove the switch from the front of the server, if you have not already done so.
Refer to “Removing a Switch From the Front of the Server” on page 1-11 for those
instructions. Do not remove the rear transition module until you have first removed
the switch.
Note – Opening the handle on the RTM shuts down both the RTM and the switch.
2. Disconnect any cables connected to the rear transition module for the switch.
3. Loosen any retention screws that fasten the module to the enclosure.
4. Open the ejectors fully, rotating the handles outward until the board disengages
from the midplane.
5. Slide the module evenly out of the enclosure.
6. Install a replacement rear transition module or a filler panel to maintain the
enclosure’s shielding and cooling performance.
Refer to Section 1.8.2.1, “Installing the Rear Transition Module for a Switch” on
page 1-14 .
Caution – Failure to cover all rear panel slots with rear transition modules or filler
panels can negatively impact the cooling of the system.
