Attaching the Mid-Bracket to the Rail
Note
The rack post must have holes on both the front and rear flanges to properly secure the rack
mount rail in either a 3-inch or 7.25-inch flush two-post rack configuration. The rack post must
have holes on the front flange to secure the rack mount rail in a mid-mount two-post rack
configuration.
The mid-bracket is used to secure the rack mount rail to the rear flange of the rack post in a flush mount
configuration or to the front flange of the rack post in a mid-mount configuration.
You can position the mid-bracket on to the rail in the following configurations:
•
3 inches in from the rack mount rail ear for securing to the rear rack post flange in a 3-inch rack post
flush mount configuration. See
•
7.25 inches in from the rack mount rail ear for securing to the rear rack post flange in a 7.25-inch rack
post flush mount configuration. See
•
7.25 inches in from the rack mount rail ear for securing to the front rack post flange for a mid-mount
configuration (the rear rack post flange is not used in a mid-mount configuration). See
page 63.
The two-post rack mount rail can be installed in both a flush mount or mid-mount configuration. In a
flush mount configuration, the rack mount rail is secured to both the front and rear flange of either a 3-
inch or 7.25-inch rack post.
