Chassis
The Acme Packet 4600 System is contained in a 1U rack-mounted chassis. It can be front-
or center mounted in standard 19” wide racks (up to 28” deep), with options for 23” wide
racks.
Mounting Hardware
The Acme Packet 4600 System is supported by a pair of cabinet slides that are affixed to an equipment rack by front and rear mounting flanges. The cabinet slides are adjustable for equipment racks of various depths.
Equipment Rack Installation Hardware
For equipment rack installations, the system chassis is outfitted with left and right
chassis-mounted slide rails. One rail is secured to each side of the chassis, that
slides into another rail that is attached to the inner posts on both sides of the
equipment rack. This two-piece mounting system simplifies chassis installation and
removal.
When installing the chassis, the user can easily slide the chassis along the slide rails until a locking clip on each chassis-mounted rail locks the chassis into the slide rails. Pressing this clip will then allow the chassis to be fully installed into the equipment rack. Once inserted into the equipment rack, the Acme Packet 4600 is secured in place with two captive thumbscrews.

The slide rails that are bolted to either side of the chassis or equipment rack are reversible and can be used on either side of the Acme Packet 4600.

Once the slide rails are installed on the chassis and on the equipment rack, the chassis can be installed in the rack by inserting the chassis slide rails into the tracks of the slide rails already mounted on the equipment rack. When the locking clip pin on the chassis slide rail meets the hole in the rack slide rail, the rails lock together. Push the locking clip pin in to continue to slide the chassis into the rack rails.

Once the chassis has been fully inserted into the rack, turning the captive thumbscrews
clockwise will lock the chassis securely into the rack.
