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 HP 1910 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.”

8
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 3 Dust concentration limit in the equipment room
Substance Concentration limit (
p
articles/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 4.
Table 4 Harmful gas limits in the equipment room

SO20.2
H2S 0.006
NH30.05
Cl20.01
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 1910 switches are Class 1 laser devices.
W
ARNING!
Do not stare into any fiber port when the switch has power. The laser li
g
ht emitted from the optical fiber
may hurt your eyes.

9
Installation tools
•Flathead screwdriver
•Phillips screwdriver
•Needle-nose pliers
•Wire-stripping pliers
•Diagonal pliers
•ESD-preventive wrist strap
•Blow dryer
All these installation tools are user supplied.

Installing the switch
CAUTION:
Keep the tamper-proof seal on a mountin
g
screw on the chassis cover intact, and if you want to open the
chassis, contact HP for permission. Otherwise, HP shall not be liable for any consequence.

Attaching the mounting brackets to the switch chassis
To attach the mounting brackets to the switch chassis:
1. Identify the correct mounting position (see Table 5).
2. Align the round holes in one bracket with the holes in the mounting position.
3. Use screws to attach the mounting bracket to the chassis.
4. Repeat the preceding steps to attach the other mounting bracket to the chassis.

Rack-mounting the switch
This task requires two persons. To mount the switch in a rack:
1. Wear an ESD-preventive wrist strap and make sure it makes good skin contact and is well
grounded.
2. Check that the rack is well grounded and can support the weight of the switch chassis and all its
accessories.
3. Check that the mounting brackets have been securely attached to the switch chassis.
4. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
5. One person holds the switch chassis and aligns the oval holes in the brackets with the mounting
holes in the rack posts, and the other person attaches the mounting brackets with M6 screws
(user-supplied) to the rack, as shown in Figure 29, Figure 30, Figure 31, or Figure 32.
NOTE:
If a rack shelf is available, you can put the switch on the rack shelf, slide the switch to an appropriate
location, and attach the switch to the rack with the mounting brackets.
