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 a
nd 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.
Table 2 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m³)
Dust
NOTE:
Dust diameter ≥ 5 μm
≤ 3 × 104 (no visible dust on the tabletop over three days)
The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and
premature aging of components, as shown in Table 3.

)
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.

Figure 12 Mounting the switch on a workbench
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.

2. Connect the other end of the grounding cable to the grounding strip.
a. Cut the grounding cable to a length according to the distance between the switch and the
grounding strip.
b. Peel 20 mm (0.79 in) of insulation sheath by using a wire stripper.
c. Use the needle-nose pliers to bend the bare wire.
d. Hook the grounding cable to the post on the grounding strip, and use the hex nut to secure
the cable to the post.
Figure 14 Connecting the grounding cable to a grounding strip

(3) Grounding cable (4) Hex nut
Grounding the switch with a grounding conductor buried in
the earth ground
If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft)
or longer angle iron or steel tube into the earth ground to serve as a grounding conductor.
11
The dimensions of the angle iron must be at least 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel
tube must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).
Weld the yellow-green grounding cable to the angel iron or steel tube and use cathodic protection to
protect the joint from corrosion.

Setting up the configuration environment
The HPE 1950 12XGT 4SFP+ switch has a serial console port and a mini USB console port. You can
access the switch through the serial console port or the mini USB console port. As a best practice,
use the serial console port to access the HPE 1950 12XGT 4SFP+ switch. To access the switch
through the mini USB console port, you need to prepare a mini USB console cable. Only the mini
USB console port is available if you connect both the serial console port and mini USB console port.
The other HPE 1950 switches have only a serial console port.
