Installing the EPS200-4850A in the same cabinet as the chassis is recommended. If the
EPS200-4850A cannot be installed in the same cabinet as the chassis, it should be placed near
the cabinet and careful attention needs to be paid to the cabling. Two EPS200-4850A work in
1+1 backup mode. Each power module provides four circuit breakers and eight AC power inputs.
Each circuit breaker is 20 A.
3.3 Heat Dissipation System
This section describes the appearance, functions, and specifications of the heat dissipation
system.
3.3.1 System Air Channel
This section describes the CX600-X16's system air channel.
The CX600-X16 is divided into an upper chassis and a lower chassis; it draws in air from the
front and exhausts air from the rear. The air intake vent on the upper chassis is located above
the board area on the front chassis; the air exhaust vent is located above the board area on the
rear chassis. The lower chassis and the upper chassis are opposites. The upper chassis and the
lower chassis also have separate heat dissipation systems.
