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. Image showing the Acme Packet 4600 Front PanelImage showing the Acme Packet 4600 Rear Panel

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. Image showing the assembled Acme Packet 4600 Slide Rail

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 locking clip is also a safety mechanism for removing the chassis from the equipment rack. When removing the chassis, the locking clip engages to prevent the chassis from being overextended and requiring the user to unlock the clip to intentionally remove the chassis.

  • 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. Image showing a rack mounted slide rail

  • 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.Image showing the locking clip latch and pin

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