NOTE:
The mounting brackets extend the width to fit into standard 19-in.
(48.3 cm) racks. The rack rails must be spaced widely enough to
accommodate the external dimensions of the PTX3000 chassis.
•
The rack must be strong enough to support the weight of the fully configured packet
transport router, up to about 200 lb (90.7 kg).
•
For service personnel to remove and install hardware components, there must be
adequate space in front of the packet transport router. At least 24 in. (61.0 cm) in front
of the rack or cabinet is required. However, NEBS GR-63 recommends at least 30 in.
(76.2 cm) in front of the rack or cabinet. See
.
•
The rack or cabinet must have an adequate supply of cooling air.
•
In a closed cabinet, we recommend at least 6 in. (15 cm) of unobstructed airflow in
front of the packet transport router, and 1 in. (2.5 cm) of unobstructed airflow behind
the packet transport router.
•
Appropriate measures such as airflow baffles must be installed to prevent recirculation
of hot air and overheating.
