4 Environment Requirements on Third-Party Cabinets
• Cabinet dustproof requirement: The MA5800-X2 subrack is not dustproof, so select
dustproof cabinets that support dust filter maintenance.
• Cabinet installation requirements:
For the MA5800-X2 service subrack, select an IEC-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.
After the MA5800-X2 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-X2.
• 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 20-A DC over-current protection mechanism and
an 8-A AC over-current protection mechanism are recommended for the MA5800-X2. 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:
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.
