Rack Mount and Power On Procedures
Rack mounting the GRF 1600

Ventilation requirements
Ventilation must comply with these requirements:
–
The installation of the GRF 1600 and other units within the rack should not reduce the
air flow within the rack. The maximum recommended ambient temperature for the
GRF is 40˚ C (104˚ F).
–
Make sure you have a two-unit air gap for cooling and cables between the GRF and
any other equipment in the rack.
Additionally, please consider the location of the GRF 1600 in relation to other devices located
in an adjacent rack. Ensure that the GRF’s air intake is not drawing directly upon heated air
from another unit. Figure 3-7 shows air intake and exhaust areas. When you install the GRF,
you must provide six to ten inches of side clearance.

Rack depth
If the media cards require flat cables, the minimum rack depth required to install a GRF 1600 is
26” (66.7 cm), and the rack must be EMI/RFI shielded.
If the media cards require round, shielded cable, the minimum rack depth should be 27” (69
cm).
Side rails
–
If you rack-mount the GRF 1600, Lucent recommends you install side rails in the
rack before attempting to insert a GRF 1600. Side rails support the 107-124 pound
unit as the team inserts the chassis and fastens it to the rack. The internal width of the
GRF 1600 chassis is 17.375” (44.1 cm).
