2.2 Unpacking

A preliminary inspection of the equipment container should be made before unpacking. Evidence of damage should be noted and reported immediately.

Unpack the equipment as follows:

∙Place the container on a clean flat surface, cut all straps, and open or remove top.

∙Take out the ASMi-450 carefully and place it securely on a clean surface.

∙Inspect the product for damage. Report immediately any damage found.

2.3 Site Requirements

AC-powered ASMi-450 units should be installed within 1.5m (5 feet) of an easily-accessible grounded AC outlet capable of furnishing the nominal supply voltage (115 or 230 VAC, in accordance with your order).

DC-powered ASMi-450 units require a -48 VDC power source.

The user's port connector, designated DCE, depends on the interface type installed on the unit:

∙V.35 interface: 34-pin female connector.

∙X.21 interface: 15-pin D-type female connector.

∙RS-530/RS-422 interface: 25-pin D-type female connector.

∙V.36/RS-422/RS-449 interface: a 37-pin D-type male connector is provided by means of an adapter cable that connects to the RS-530/RS-422 connector.

∙Ethernet interface: shielded RJ-45 connector (supports both UTP and STP media).

Appendix A provides information on the pin allocation of the user's port connectors, and for the adapter cable.

The HDSL line of the ASMi-450 is terminated in an RJ-45 connector. Appendix A provides the pin allocation for this connector.

Allow at least 90 cm (36 inches) of frontal clearance for operator access. Allow at least 10 cm (4 inches) clearance at the rear of the unit for interface cable connections.

The ambient operating temperature of the ASMi-450 should be 32 to 122°F (0 to 50°C), at a relative humidity of up to 90%, non-condensing.
