Caution: If the operating temperature rises above the 40º C limit an internal
thermal protection device will shut off the Access Bank II - SNMP. When the
temperature is reduced below this threshold, the Access Bank II - SNMP
restarts.
• An installation site below 10,000 feet (3,048 m).
• For operation outside these ranges, the Access Bank II - SNMP must be placed in an
environmentally controlled enclosure.
Caution: When you mount the chassis, do not allow the Access Bank II -
SNMP to remain in direct contact with any combustible surface.
4.4 Wall Mounting
The adapter brackets attached to the Access Bank II - SNMP are positioned at shipment for wall-
mounting. To wall-mount the unit:
1. Select a location that meets the criteria specified above. Leave at least 1/2 inch clearance
below the chassis for ventilation. Leave at least 6 inches in front of the Access Bank II -
SNMP Control Panel for access to its switches and LEDs and at least 18 inches behind the
back plate for maintenance.
2. To create a 3/4 inch offset between the Access Bank II - SNMP chassis and the wall surface
for better ventilation, mount a 3/4 inch thick piece of plywood (at least 20 inches vertically
by 14 inches horizontally) on the wall using fasteners appropriate for mounting a heavy
object (see Figure 4-1).
3. Mount the Access Bank II - SNMP chassis to the plywood with eight #8 x 3/4” pan-head (or
larger) wood screws (Figure 4-1).

The Access Bank II - SNMP can be rack-mounted using several dif fer ent me thods. The small adapt er
brackets shipped with the unit can be used to mount the unit in a st andar d 19” r ack wit h a typic al fi ve-
inch offset. Using the recommended heavy-duty brackets, you can mount the Access Ban k II - SNMP
in either a 19” or 23” rack with a custom offset.
