Setting Hybrid Balance Straps For A Did [Ddi] Trunk On An Sla; Installing Did Trunks On An Sla (Usa Only) - Mitel MiVoice Office 250 Installation And Administration Manual

To wall-mount an SLA unit:
1. Remove the two screws on one side of the unit and use them
to attach the two L-shaped wall-mounting brackets. See the
figure at right.
2. Position the SLA on the MDF backboard and mark the loca-
tion of the mounting screw holes on the wall. Set the SLA
aside.
3. Drive a screw into the center of each mounting hole marking,
allowing the heads of the screws to protrude slightly. Use
screws of sufficient strength to support the SLA.
4. Hang the SLA on the screws. If necessary, adjust the screws
to ensure the SLA is held firmly in place.

2. For each modular jack assembly mounted in step 1, mount a corresponding four-conductor
modular jack assembly near the SLA location.
3. To connect the modular jack assemblies mounted in steps 1 and 2:
a. Run one-pair cable between the corresponding modular jack assemblies.
b. Wire each end of the one-pair cables onto their respective modular jack assemblies. For a
