Removing the Outer Rails From the Rack

In the uncommon event that it is necessary to remove the outer rails from the rack,
follow these instructions. The chassis must be out of the rack.
Releasing the Outer Rails
1. On the front of the outer rail, slide the small plastic safety slider (red in
drawing) up and hold it while pushing the plastic release button (green in
drawing) just below it.
2. While holding the release button in, pull the outer rail forward to disengage
the pins and the front of the rail from the rack.
3. Support the front of the outer and middle rail assembly while releasing the
rear.
4. Remove the outer rail from the rear of the rack in the same way as the front.
Slide the safety slider up and push and hold the release button, then pull the
rear pins out of the rack and remove the rail.

Note: A small number of customers may have received a different outer rail than
the one pictured. This rail features side release latch on the front of the outer rail,
which opens inward to release the outer rail from the rack. Contact Supermicro's
Technical Support department if you need additional assistance.

Installing the Cable Management Arm

The SC227 chassis supports a cable management arm (CMA) that allows servicing
while the server is running. The CMA keeps the rear cables organized and clear of
the rail mechanisms when the system is extended out the front of the rack. The kit
includes six fabric Velcro cable ties.
Figure 2-8. Cable Management Arm and Velcro Straps
The CMA attaches to the rack mounting rails by means of four connectors. They
are labeled on the connectors 1, 2, 3, and 4.
Installing the Cable Management Arm
1. Slide CMA connector #1 forward onto the two posts on the rear of the right
inner rail (right side when viewed from the front). It snaps into place.
2. Slide CMA connector #2 forward onto the two posts on the rear of the right
middle rail. It snaps into place.
