4 Environment Requirements on Third-Party
Cabinets
• The EA5801E is a device with left-to-right ventilation channels and must be deployed in a cabinet
with non-blocking air intake vents on the cabinet door.
• When the device is installed together with other active devices in an indoor cabinet, you are advised
to reserve 1 U space for heat dissipation above and under the device respectively to reduce the
impact on other components in the cabinet, and the working temperature must be less than 65 ℃.
• When installing in an outdoor cabinet, the working environment temperature requirement is less
than 65 ℃.
Space Requirements
Heat Dissipation Requirements
• Cabinet requirements:
For the EA5801E service subrack, select an IEC-compliant cabinet with a depth of 300 mm or more
so that a space with a depth of 70 mm or more can be reserved for cable/fiber routing after boards
are installed.
• Cabinet door requirement: When devices are operating, keep the cabinet door closed.
Indoor cabinet
Power Distribution Requirements
Dustproof Requirement
Ensure that an over-current protection mechanism has been deployed on the upper-level device. A less
than or equal to 20 A over-current protection mechanism are recommended for the EA5801E. Ensure
that the circuit breaker trip value of the upper-level device is greater than or equal to the rated value
on the device nameplate.
The EA5801E subrack is not dustproof, so select dustproof cabinets that support dust filter maintenance.
