Acme Packet provides flexible mounting options for your Acme Packet 4600 equipment rack installation.

The mounting system consists of a slide rail mounted on each side of an equipment rack and a chassis slide rail mounted on each side of the Acme Packet 4600 chassis. Once the slide rails are installed on the equipment rack and chassis, the chassis can be slid into place by aligning the installed chassis slide rails along the guides on the equipment rack slide rails. When the Acme Packet 4600 is fully inserted into the equipment rack, it is secured in place with two captive thumbscrews.

In the first stage of system installation, secure the equipment rack slide rail to the equipment rack. The painted end of the equipment rack slide rail attaches to the front of the equipment rack and the bare steel side attaches to the rear of the equipment rack. The equipment rack slide rail can expand and contract to accommodate equipment racks of various depths up to 32”.

You can mount the equipment rack slide rail to both tapped hole rack and square rack. Follow the appropriate procedure below.

1. Locate the following components: Assembled equipment rack slide rails (2), #10-32 x 5/8” screws (8), Mounting spacers (2)
2. Line up the painted side of the equipment rack slide rail with an appropriate mount point on the front of the equipment rack.
3. For both holes in the flange, place one #10-32 x 5/8” screw through the mounting spacer, then through the slide rail flange and into the tapped hole.
4. Using a #2 Phillips head screwdriver, tighten the screws to secure the slide rail to the equipment rack. Do not completely torque the screws; leave a small amount of play at this time.
5. Expand and line up the unpainted side of the equipment rack slide rail on the outside of the rear rack slide rail at the same height used for the front mount point.
6. For both holes in the slide rail flange, place one #10-32 x 5/8” screw through the flange and into the tapped hole, and screw them into place.

This section explains how to cable the NIU for media and signaling. The NIU is available with either copper or optical SFP Ethernet connectors. The media and signaling ports that can be configured are either any combination of P0, P1, P2, and P3, or P4 and P5; not a mixture of the 1GbE and 10GbE ports.

This section explains how to cable a Acme Packet 4600 configured with a GbE optical NIU. Standard single mode or multimode fiber optic cabling with duplex LC connectors are used to connect the Acme Packet 4600 SFP-based NIUs to your network.

You can use one or two connections for HA redundancy support between the two members of an HA node. Using two rear interfaces for sharing redundancy information provides a high level of reliability. As a rule, network management ports should be used in this way:

• Mgmt0 should be reserved as the boot/maintenance interface.
• Mgmt1 and Mgmt2 are available for sharing HA information.

Management network ports feature automatic crossover negotiation so that a crossover cable is not necessary for HA cabling.

To cable Acme Packet 4600 in an HA configuration using single rear interface support:

1. Insert one end of an Ethernet cable into either Mgmt1 or Mgmt2 on the rear panel of the Acme Packet 4600 A. The release tab on the RJ45 jack clicks into place when you insert it properly.
2. Insert the other end of the Ethernet cable into the corresponding management interface on the rear panel of the Acme Packet 4600 B. The release tab on the RJ45 jack clicks into place when you insert it properly. If you use Mgmt1 on Acme Packet 4600 A, then you will connect it to Mgmt1 on Acme Packet 4600 B.
3. Refer to the configuration procedures located in the HA Nodes chapter of the Acme Packet Configuration Guide .

NIU media port cabling in an HA node depends on network topology. After a switchover between the two Acme Packet 4600 s in an HA node, the standby system sends out an ARP message using a configured virtual MAC address, establishing that MAC on another physical port on the same Ethernet switch.
