Reattach the side panel and tighten the 216 HEX security nut to secure it to the main chassis.
The transparent Lexan panel in the front cover makes slight contact with the card handles when it is reattached.
This prevents walk-out due to vibration and is a standard feature of the HRE-204.
When the main chassis is attached to the backplate, it can be rotated down to provide access
to the backplane connector and other internal areas. Unlatch the chassis from the two friction
clasps in the upper corner of the backplate to lower it. See
for hinging details.
