How to Properly Install a Huawei Switch in a Data Center

1. Device Introduction

When receiving the switch, you will find accessories and specifications inside the package.

2. Installation Requirements

2.1 Environmental Requirements

The device must be placed in a clean, dry, well‑ventilated room with controllable temperature, free from water leakage or condensation.

Dust control is essential to prevent static discharge and poor contact of metal connectors.

Maintain temperature and humidity within the operating range specified in the table.

2.2 Rack Requirements

Select a rack based on the switch height; most switches fit a standard 19‑inch rack such as N66E or N68E.

Rack depth should be at least 600 mm. For 600 mm depth, ensure a single‑door rack with sliding rails or trays, and keep a minimum clearance of 95 mm (or 100 mm for 800 mm depth) from the front panel.

3. Device Installation

3.1 Install Sliding Nuts and Rails

Pay attention to left/right orientation and front/rear ends of the rails to avoid reverse installation.

Adjust rail length using positioning blocks and hooks, then secure with screws. If rails are unavailable, use trays as substitutes.

3.2 Mount Device into Rack

4. Installation Modules

5. Cable Connections

Before connecting cables, attach the grounding cable first, then the remaining cables.

5.1 Installation Precautions

Never install power cables while energized.

Ensure the power module switch is OFF before connecting power cables.

Use the supplied power cable that matches the switch’s current rating.

5.2 Signal Cable Precautions

Insert dust caps on unused optical ports and modules.

Fiber bend radius must be at least 20 times the fiber diameter (≥ 40 mm).

Do not over‑tighten fiber bundles; allow free movement.

Test Ethernet cables with a continuity tester before use.

5.3 Cable Routing

Label both ends of each cable with temporary tags indicating the corresponding interface.

Power cables must not obstruct other power modules.

Secure power and ground cables with ties spaced about 250 mm; maintain at least 30 mm separation from signal cables.

When cable density is high, use a three‑layer routing scheme to keep cables organized and non‑crossing.

Secure network cables to the rack with ties every ~250 mm.

Bundle fibers with fiber‑specific ties, then fix them to the rack.

Place fiber bundles into corrugated tubing, seal both ends with tape, feed the tubing through the rack’s cable entry hole (~100 mm), and secure.

6. Switch Cluster Card Setup

The switch supports cluster cards; a clustered switch must have both primary and backup control boards installed, and the control board must occupy the designated slot.

Important Notes

When installing cables, optical modules, or fibers, a “click” sound indicates proper seating.

To remove cables or modules, grip the release tab, push slightly inward, then pull out.

7. Power‑On Procedure

Before powering on, ensure all power module breakers are OFF.

Verify input voltage is within the power module’s specifications.

First turn on the external power supply, then the switch’s power module.

When the power module indicator shows “RUN” or “INPUT/OUTPUT” green steady, check other component indicators.
