SmartEdge 600 Chassis

The SmartEdge 600 chassis is NEBS compliant and designed for mounting in a
standard 19- or 23-inch rack.
5.7.1 Chassis Card Cage
The SmartEdge 600 chassis has a card cage with 14 slots. Two slots are
dedicated to the controller cards and 12 slots are available for a flexible
combination of line cards.
All cards are installed at the front of the chassis. A cable tray provides
the means to route the cables from the front of the chassis to the external
equipment.
The rear of the chassis has connectors for alarm outputs, status inputs, dual
external timing inputs for synchronization, and dual RS-232 ports for local
connections.
Note: The operating system does not support the alarm, status, and RS-232
Electrostatic discharge (ESD) jacks are located on both the front and the rear of
the chassis.
5.7.2 Chassis Cooling
Cooling for the chassis is provided by the fan tray installed directly above the
card slots. Six fans provide the needed airflow from the bottom of the chassis
to the top with exhaust at the rear of the chassis. An air filter is installed below
the card cage.
A single fan failure does not impact the operation of the system; however, to
prevent overheating, the unit must be replaced as soon as possible.
Risk of equipment damage. Every slot must have a controller, line, or blank
card installed in it. SmartEdge 600 cards can be damaged by lack of cooling
when the chassis has empty slots.
5.7.3 Chassis Power
The SmartEdge 600 router power architecture has one power zone with primary
(A) and backup (B) sources. For a fully redundant power configuration, both
sources must be connected.
