4 Environment Requirements on Third-Party Cabinets
• Cabinet dustproof requirement: The MA5800-X7 subrack is not dustproof, so select
dustproof cabinets that support dust filter maintenance.
• Cabinet installation requirements:
For the MA5800-X7, select an IEC60297-compliant cabinet with a depth of 300 mm or more
so that a space with a depth of 55 mm or more can be reserved for cable/fiber routing after
boards are installed.
When the MA5800-X7 is installed in an ETSI-compliant cabinet that meets the related
requirements, replace the mounting ears with the ETSI-compliant mounting ears customized
by Huawei for the MA5800-X7.
• Cabinet door requirement: When devices are operating, keep the cabinet door closed.
• Grounding requirement: Huawei cabinets are grounded through mounting bars. Ensure that
third-party cabinets are properly grounded based on site conditions.
• Power distribution requirements: Ensure that an over-current protection mechanism has
been deployed on the upper-level device. A 40-A over-current protection mechanism is
recommended for the MA5800-X7. 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.
• Heat dissipation requirements:
The fan tray of the MA5800-X7 dissipates heat from the left to the right in air blowing. When
being installed on multiple open racks in parallel, do not install the device supporting air
blowing on the neighboring rack to avoid serial ventilation.
Ensure that the cabinet has an air inlet and the hole density of the cabinet door is 60% or
higher.
When a cabinet accommodates multiple subracks or the device shares a cabinet with other
active devices, ensure that the following space requirements are met.
