Unpack and Inspect Stratum 3 Clock Cabinet
1 Check the status of the SHOCKWATCH and/or TILTWATCH indicators on the
cardboard container. If the container has been jarred or tilted beyond specifications, the
indicators are red, indicating possible damage.
2 Remove all packing material.
3 Remove front door and rear screw-on panels from the cabinet.
4 Inspect the cabinet for damage. Report any damage per local instructions.
Install and Position Stratum 3 Clock Cabinet
Check the location of the AC power receptacle. The receptacle must be on a separately fused
circuit that is not controlled by a wall switch. It must be located within 10 ft. (3 m) of the
cabinet and should be located outside the MDF area.
1 Position the clock cabinet in the designated location.
2 If earthquake protection is required, skip to‘‘Install Earthquake Protection for Avaya
SCC1 Media Gateway’’ on page 103 or ‘‘Install Earthquake Protection for Media
Gateway’’ on page 68
3 If earthquake protection is not required, level the cabinets and adjust and lock the cabinet
stabilizing bolts to keep the cabinet from moving.
Connect AC Power to Stratum 3 Clock Cabinet
The clock cabinet requires a 120 VAC, 15 amp receptacle. The green wire ground provided by
the receptacle is sufficient. The clock cabinet does not require a ground connection back to the
single-point ground.
