Safety recommendations

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

Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with a 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.

Ensure good ventilation at the installation site and keep the air inlet and outlet vents of the switch free of obstruction.

Connect the yellow-green protection grounding cable before the switch is powered on.

Make sure the power source voltage is as required.

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

To avoid ESD damage, wear an ESD wrist strap when hot-swapping a power supply.

Examining the installation site

The HPE OfficeConnect 1950 switches must be used indoors. You can mount your switch in a rack or on a workbench, but make sure the following conditions exist:

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

1

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 reliably grounded.

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

Temperature/humidity

Maintain temperature and humidity in the equipment room as described in "Technical specifications."

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

Lasting low relative humidity can cause washer contraction and ESD and introduce problems such as loose captive screws or 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 of different switch models, see "Appendix A Chassis views and technical specifications."

Cleanliness

Dust buildup on the chassis might 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.

EMI

All electromagnetic interference (EMI) sources from outside or inside of the switch and application system adversely affect the switch in the following ways:

A conduction pattern of capacitance coupling.

Inductance coupling.

2

Electromagnetic wave radiation.

Common impedance (including the grounding system) coupling. To prevent EMI, use the following guidelines:

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

Keep the switch far away from radio transmitting stations, radar stations, and high-frequency devices to make sure the EMI levels do not exceed the compliant range.

Use electromagnetic shielding when necessary. For example, use shielded interface cables.

Laser safety

WARNING!

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

The HPE OfficeConnect 1950 switches are Class 1 laser devices.

Grounding the switch

WARNING!

Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.

The power input end of the switch has a noise filter, whose central ground is directly connected to the chassis to form the chassis ground (commonly known as PGND). You must securely connect this chassis ground to the earth to minimize the potential for system damage, maximize safety at the site, and minimize EMI susceptibility of the system.

You can ground the switch in one of the following ways, depending on the grounding conditions available at the installation site:

Grounding the switch with a grounding strip

Grounding the switch with a grounding conductor buried in the earth ground

NOTE:

The power and grounding terminals in this section are for illustration only.

Grounding the switch with a grounding strip

WARNING!

Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod.

If a grounding strip is available at the installation site, use the grounding strip to ground the switch. To ground the switch by using a grounding strip:

1.Connect one end of the grounding cable to the grounding screw on the switch.

a.Remove the grounding screw from the rear panel of the switch chassis.

b.Attach the grounding screw to the ring terminal of the grounding cable.

c.Use a screwdriver to fasten the grounding screw into the grounding screw hole.

Connecting the switch to an A-RPS1600

1.Orient the plug with the power receptacle on the power supply, and insert the plug into the receptacle (See callout 1 in Figure 18).

If you cannot insert the plug into the receptacle, re-orient the plug rather than use excessive force to push it in.

2.Tighten the screws on the plug with a flat-blade screwdriver to secure the plug in the RPS receptacle. See callout 2 in Figure 18.

3.Connect the other end of the power cord to an A-RPS1600.

Connecting the switch to an A-RPS800

1.Remove the cover over the DC-input receptacle on the switch as shown in Figure 19. Reinstall the cover if you are not to connect a power cord to the receptacle.

2.Align the plug of the power cord with the DC-input receptacle on the power supply, and insert the plug into the power receptacle. See callout 1 in Figure 20.

If you cannot insert the plug into the receptacle, re-orient the plug rather than use excessive force to push it in.

3.Tighten the screws on the plug with a flat-blade screwdriver to secure the plug in place. See callout 2 in Figure 20.

4.Connect the other end of the power cord to the A-RPS800.

Verifying the installation

After you complete the installation, verify the following items:

There is enough space for heat dissipation around the switch.

The rack or workbench is stable.

The grounding cable is securely connected.

The correct power source is used.

The power cords are correctly connected.

All the interface cables are cabled indoors. If any cable is routed outdoors, verify that the socket strip with lightning protection and lightning arresters for network ports have been correctly connected.
