1 Precautions

•After routing the cable, attach the label or fasten the tag to the cable 20 mm away from the

connector.

•After the label for the signal cable is attached to the signal cable, the rectangular text area of

the label must face rightwards or downwards.

•After the identification plate for the power cable is attached to the power cable, the text area of

the plate must face rightwards or upwards. Ensure that the side attached with the label faces

outwards.

•This document aims to provide simple and distinctive guidelines for hardware installation.

•This document does not describe operations for the pre-delivery installation. Instead, this

document describers only the operations for on-site installation.

Electrostatic Discharge

Before touching the device, or holding the boards and IC chips, wear the ESD gloves or the

ESD wrist strap to prevent the electrostatic discharge of the human body from damaging the

sensitive components. Ensure that the other end of the ESD wrist strap is properly grounded.

•The distance between cable ties or binding straps inside the cabinet must be within 250 mm.

(For user cable, the distance must be within 200 mm.)

•Use a diagonal pliers to cut off the extra part of the cable tie to the end, and ensure that the

cable tie is neat without sharp edges to prevent hand injury.

3 Appearance and Structure

The MA5800-X7 service subrack is 6 U high, and has a fan tray at the right. The subrack is

installed in the cabinet through the ETSI or IEC mounting ears.

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.

Front view Side view

Airflow blocking object

•The MA5800-X7 supports left-in right-out heat dissipation, so the cabinet must have an

unblocked air inlet on its door.

•You are advised to reserve more than 4 U space above and under the MA5800-X7

respectively to minimize the impact on other components in the cabinet.

5 Space Requirements on Third-Party Cabinets

Without an air deflector With an air deflector

Front view Side view Front view Side view

10U

If the MA5800-X7 subrack is installed in a subrack with B-T airflow, you are advised to add

an air deflector to the subrack so that the hot air does not direct flow to the MA5800-X7.

When 2 U space is reserved at the air inlet and 3 U space is reserved at the air outlet, the

cabinet panels will have less impact on the heat dissipation of the MA5800-X7.

deflector

(3 U)

•Reserve 10 U space between the devices or add a 3 U air deflector to redirect air flows to

minimize the mutual heat dissipation impacts on the devices.

•Reserve at least 4 U space when you route fibers or install other passive devices to facilitate

subsequent air inlet or dust filter cleaning.

6 Installing the Service Subrack

Remove IEC mounting ears

•The MA5800-X7 service subrack is configured with IEC (19-inch) mounting ears by default.

The MA5800-X7 subrack can be mounted in an IEC cabinet or rack. To install the MA5800-X7

subrack in an ETSI cabinet, uninstall the IEC mounting ears, and then install the ETSI (21-

inch) mounting ears.

•Before installing the service subrack, it is advised to install cable managers or sliding rails in

the cabinet or rack for supporting the service subrack.
