DCRS-7600 InstallManual
The operating ambient temperature of the DCRS-7604 is 0 ~ 45°C, the thermal
design of the equipment can ensure that the surface temperature of the device will not
exceed the 50°C to 80°C, the highest temperature allowable.
The switch uses fan assemblies to disperse heat, with the air flow being drawn in
through the right section and out through the left section to facilitate air circulation, so that
the switch can maintain normal operation under specified environmental conditions. The
fan tray is attached to the fan tray slots left the board rack, and ventilation is provided via 4
axial fans that pump out air. Fan trays are hot swappable for maintenance, their status are
indicated by the FAN indicators on the main switch panel. In addition, dust gauze is
provided on the right of the board rack for filtering the air circulating through the rack. The
dust gauze can be unplugged and removed through the back for maintenance.
