Note:
See Important safety instructions when using your telephone equipment on page 265 for
basic safety precautions to follow when using your telephone equipment.
Space requirements
The B5800 Branch Gateway control unit and external expansion modules are designed to be
installed either in a free-standing stack or into a 19-inch rack system. Rack installation requires
a rack mounting kit for each control unit and expansion module. See
Rack mounting on
page 69 for more information. If there are no external expansion modules used in the
installation, the control unit can be wall mounted using a wall mounting kit. See Wall
mounting on page 67 for more information.
Cable clearance
Clearance must be provided at the front and rear of all modules for cable access. Allow
a minimum clearance of 90mm (3.5 inches).
Additional clearance
Care should be taken to ensure that the positioning of the modules does not interrupt air
flow and other environmental requirements. The control unit has ventilation slots at the
side that must not be blocked. See
Environmental requirements on page 49 and Rack
space requirements on page 52 for more information.
Cable access
Power cords must not be attached to the building surface or run through walls, ceilings,
floors and similar openings. Installation measures must be taken to prevent physical
damage to the power supply cord, including proper routing of the power supply cord and
provision of a socket outlet near the fixed equipment or positioning of the equipment near
a socket outlet.
Control unit
When wall mounted, a clearance of 500mm is required on all sides. The ventilation slots on
the rear and sides should not be covered or blocked.
