Preparing for installation

Safety recommendations

To avoid any equipment damage or bodily injury caused by improper use, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.

Before cleaning the switch, unplug all power cords. Do not clean the switch with wet cloth or liquid.

Do not place the switch near water or in a damp environment. Prevent water or moisture from entering the switch chassis.

Do not place the switch on an unstable case or desk. The switch might be severely damaged in case of a fall.

Ensure proper ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.

Make sure that the operating voltage is in the required range.

To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.

When replacing FRUs, wear an ESD-preventive wrist strap to avoid damaging the units.

Examining the installation site

The 5120 EI and 5120 SI switches must be used indoors. You can mount your switch in a rack or on a workbench, but make sure:

Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.

The rack or workbench has a good ventilation system.

The rack is sturdy enough to support the switch and its accessories.

The rack or workbench is well earthed.

To ensure normal operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections.

Temperature/humidity

Maintain appropriate temperature and humidity in the equipment room.

Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical property change of materials, and metal corrosion.

Lasting low relative humidity can cause washer contraction and ESD and bring problems including loose captive screws and circuit failure.

High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch.

For the temperature and humidity requirements, see “Appendix A Technical specifications.”

13

Cleanness

Dust buildup on the chassis may result in electrostatic adsorption, which causes poor contact of metal components and contact points, especially when indoor relative humidity is low. In the worst case, electrostatic adsorption can cause communication failure.

Table 4 Dust concentration limit in the equipment room

Substance

Concentration limit (particles/m³)

Dust

≤ 3 x 104 (no visible dust on the tabletop over three days)

NOTE:

 

Dust diameter ≥ 5 μm

 

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table 5.

EMI

All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling, electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To prevent EMI, take the following actions:

If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid.

Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices.

Use electromagnetic shielding, for example, shielded interface cables, when necessary.

Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes.

Laser safety

The HP 5120 EI and 5120 SI switches are Class 1 laser devices.

WARNING!

Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber may hurt your eyes.

Installing the switch

CAUTION:

Keep the tamper-proof seal on a mounting screw on the chassis cover intact, and if you want to open the chassis, contact your local HP agent for permission. Otherwise, HP shall not be liable for any consequence caused thereby.
