1. Installing the Cabinet 1-3 Unpacking Unpack the equipment and check it against your equipment lists. Inspect for physical damage. If you are not sure about a compo- nent’s function, review the Product Description Manual. Contact your Sales Representative if you have additional questions. Have the appropriate tools for the job on hand, including: a test set, a punch down tool and a digital voltmeter. Before Installing Make sure you have a building plan showing the location of the common equipment, extensions, the telco demarcation and earth ground. In addition, the installation site must meet the requirements outlined in the Standard Practices Manual. Site Requirements The common equipment is contained in the wall-mounted Main Equipment Cabinet. Choose a central location for the cabinet that allows enough space for the equipment — and provides enough room for you to comfortably work. The Installation Layout (Figure 1-1 on the next page) shows you abouthow much space your system requires. INSTALLING THE CABINET
1-4 Planning the Installation (Figure 1-1) Before installing the common equipment, you should mount a Main Distribution Frame (MDF) plywood backboard in a cen- trally located spot. A 1/2 sheet of plywood (4’ x 4’) should be more than adequate. Mount this backboard using suitable fas- teners, taking care to adhere to standard installation practices and local codes. The equipment cabinet requires a three-prong, dedicated 110 VAC 60 Hz circuit (NEMA 5-15 receptacle) located within 7 feet of the AC receptacle. Normally, you install the extension and trunk blocks to the right of the Main Cabinet. Telco should also install the RJ21X to the right of the Main Cabinet.

Unscrew the two captive screws on the front of the cabinet cover. 2. Lift up slightly on the front of the cover — then gently slide the cover back to remove it.

1-6 Unpacking the Wall Mount Bracket(Figure 1-3) The wall mount bracket and screws are taped to the packing mater- ial in the Main Equipment Cabinet box. Unpack the wall mount bracket and mounting screws. Figure 1-3 WALL MOUNT BRACKET Mounting the Wall Mount Bracket(Figure 1-4) Mount the wall mount bracket on the MDF in a convenient loca- tion, about 12” higher than where you want the bottom of the cabi- net to line up.

1. Installing the Cabinet 1-7 Hanging the Cabinet(Figure 1-5) 1. Hang the Main Equipment Cabinet on the wall mount hang- er as shown at right. 2. Using the remaining two screws that were packed with the hanger, secure the cabinet to the plywood backboard. Figure 1-5 HANGING THE CABINET 80000 - 13 INSTALLING THE CABINET
1-8 Removing the Right Side Panel (Figure 1-6) Remove the cabinet right side panel to gain easy access to the ground lugs and system cabling. The cabinet has two ground connections: ETH (Earth Ground) and PBXG (PBX Ground). 1. Remove the two screws that secure the right side panel to the cabinet. 2. Carefully slide the right side panel down until it swings clear of the cabinet. Figure 1-6 REMOVING THE SIDE PANELS 80000 - 16 GROUNDING THE CABINET
1. Installing the Cabinet 1-9 Attaching the Ground Wires (Figures 1-7 and 1-8) The system provides two ground terminations. Each ground connects from the system to the ground termination using 12 AWG stranded copper wire (see Figure 1-7).. Use the ETH (Earth Ground) for safety/system ground. You mustconnect ETH to a known earth ground.. Use the PBXG (PBX Ground) if you have trunks that require telco ground (such as ground start trunks). This ground is not required for loop start trunks. 1. Remove the lug on the ground connection you want to connect. 2. Following Figure 1-8, run the ground wire(s) through the RFI Suppressor Assembly as shown. 3.For Ear th Gr ound: Run a ground wire from the ETH lug to a known earth ground. For PBX Gr ound: Run a ground wire from the PBXG lug to the telco ground. 4. Crimp ring terminals as required to the ground wires. 5. Reinstall and firmly tighten the lug(s) removed in step 1 above. Do not plug in the power cord or reinstall the right sidepanel until all PCB installation and cabling are complete.

1-10 Figure 1-8 INSTALLING THE RFI SUPPRESSOR 80000 - 35 GROUNDING THE CABINET !! Install RFI Suppressor Assemblies as shown below !! You must install separate RFI Suppressor Assemblies for the ground wire, the CPU connections (i.e., mod jack and RS-232 cables), each trunk cable and each station cable. The suppres- sors mustbe mounted inside the cabinet and as close to the appropriate PCB as possible.
