Optical ILA Clearance Requirements for Airflow and Hardware Maintenance

When planning the site for an optical ILA installation, you must allow sufficient clearance around the
installed chassis (see Figure 18 on page
Figure 18: Clearance Requirements for Airflow and Hardware Maintenance for an Optical ILA
Follow these guidelines:
For the cooling system to function properly, the airflow around the chassis must be unrestricted. See
"Optical ILA Cooling System Description" on page 29
the chassis.
If you are mounting an optical ILA in a rack or cabinet with other equipment, ensure that the exhaust
from other equipment does not blow into the intake vents of the optical ILA chassis.
You must leave at least 24 in. (61 cm) both in front of and behind the optical ILA. For service personnel
to remove and install hardware components, you must leave adequate space at the front and back of
the optical ILA. NEBS GR-63 recommends that you allow at least 30 in. (76.2 cm) in front of the rack or
cabinet and 24 in. (61 cm) behind the rack or cabinet.
