Surface Mounting

4.5.1 Rack Mounting with Brackets Shipped with Unit

To mount the Access Bank II - SNMP in a standard EIA 19-inch Telco equipment rack using the included adapter brackets:

1.Remove the two front adapter brackets, rotate them 90 degrees and re-attach the brackets so they face toward the unit back plate (Figure 4-2). This creates a standard five-inch offset mounting typical of telecommunications equipment.

2.Select an appropriate location in the rack with at least 1 3/4 inches of clearance above and below the chassis for ventilation. Also ensure that there is at least 6 inches in front of the Control Panel for access to its controls and DIP switches, and at least 18 inches behind the back plate for maintenance.

3.Mount the chassis using 10-32 x 3/4” machine screws appropriate for a Telco rack (Figure 4- 3).

Note: The optional heavy-duty rack mounting brackets (see Figure 4-4) can significantly increase static strength and provide a custom front-to-back offset when mounting the units on either 19” or 23” racks (see Figure 4-3).

4.5.2 Mounting with Heavy-Duty Brackets

1.Remove the four small front adapter brackets from the Access Bank II - SNMP.

2.Attach the heavy-duty brackets to the Access Bank II - SNMP using the screws included in the heavy-duty bracket kit (see Figure 4-3).

3.Select an appropriate location in the rack with at least 1 3/4 inches of clearance above and below the chassis for ventilation. Also ensure that there is at least 6 inches in front of the Control Panel for access to its controls and DIP switches, and at least 18 inches behind the back plate for maintenance.

4.Mount the chassis on the rack using 10-32 x 3/4” machine screws appropriate for a Telco rack (Figure 4-3).

4.6Surface Mounting

To surface-mount the Access Bank II - SNMP as a desktop stand-alone, simply place it on a flat, sta- ble, non-combustible surface with at least 1/2 inch ventilation clearance below the unit. Leave at least 6 inches in front, and 18 inches in back of the chassis for ventilation and access to its controls. Leave at least 3/4” above the chassis for required ventilation.
