Safety recommendations
To avoid possible bodily injury and equipment damage, read all safety recommendations carefully
before installation. Note that the recommendations do not cover every possible hazardous condition.
General safety recommendations
•Keep the chassis clean and dust-free.
•Do not place the switch on a moist area, and avoid liquid flowing into the switch.
•Make sure the ground is dry and flat and anti-slip measures are in place.
•Keep the chassis and installation tools away from walk areas.
•Do not wear loose clothing, jewelry (for example, necklace) or any other things that could get
caught in the chassis when you install and maintain the switch.
Electricity safety
•Clear the work area of possible hazards, such as ungrounded power extension cables, missing
safety grounds, and wet floors.
•Locate the emergency power-off switch in the room before installation so you can quickly shut power
off when an electrical accident has occurred.
•Unplug all external cables, including power cords, before moving the chassis.
•Do not work alone when the switch has power.
•Never assume that power has been disconnected from a circuit. Always check.

Handling safety
CAUTION:
•When moving the switch, hold the handles at both sides of the chassis.
•Do not hold the handle of the fan assembly, power supply, or back cover of the chassis, or the air vents
of chassis. Any attempt to move the switch with these parts might cause equipment dama
g
e and even
bodily injury.
When you move an HP 7500 switch, follow these guidelines:
•Remove all external cables, including the power cords, before moving the chassis.
•Moving the chassis requires at least two persons, and you can use a mechanical lift as needed.
•Lift and put down the chassis slowly and never move suddenly.
ESD prevention
To prevent electric components from being damaged by electrostatic discharge (ESD), follow these
guidelines:
•Ground the switch correctly. For how to ground your switch, see "Installing the switch."
•Always wear an ESD wrist strap and make sure it is well grounded when installing FRUs. For how
to use an ESD wrist strap, see "Installing FRUs."
•Hold a PCB by its edges. Do not touch any electronic components or printed circuit.
•Put cards away in ESD bags for future use.
Laser safety
W
ARNING!
Do not stare into any fiber port when the switch has power. The laser li
g
ht emitted from the optical fiber
might hurt your eyes.
The 7500 switches are class 1 laser products.
Examining the installation site
The 7500 switches must be used indoors. To ensure normal operation and long service life of your switch,
the installation site must meet the requirements in this section.
Floor loading
Make sure the floor can support the total weight of the rack, chassis, cards, power supplies, and all other
components. Additionally, the floor loading plan must also consider system expansion, such as adding
more cards.

3
Temperature
CAUTION:
If condensation appears on the chassis when you move it to a high-temperature environment, dry the
chassis before powering it on to avoid short circuits.
To guarantee the normal operation of the switch, the room temperature must meet the requirements
in Table 2.

Operating temperature 0°C to 45°C (32°F to 113°F)
Storage temperature –40°C to +70°C (–40°F to +158°F)
Humidity
Maintain appropriate humidity in your equipment room, as described in Table 3.
•Lasting high relative humidity tends to cause poor insulation, electricity creepage, mechanical
property change of materials, and corrosion of metal parts.
•Lasting low relative humidity is likely to result in loose screws due to washer contraction, and even
ESD, which causes the circuits to fail.

Cleanness
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 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:
•Take measures against interference from the power grid.
•Use a grounding system and lighting protection system for the switch separate from those for other
electric equipment, and keep them far away as possible.
•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 over-voltage
or over-current caused by lightning strikes.
Grounding
Using a good grounding system to protect your switch against lightning shocks, interferences, and ESD
is essential to the operating reliability of your switch.
Make sure the resistance between the chassis and the ground is less than 1 ohm.
Power
Perform the following tasks to meet the power requirements:
1. Calculate the total power consumption
The total power consumption varies by card type and density and fan assembly power
consumption. If the switch provides PoE power, the total power consumption must also include PoE
power consumption. For more information about total power consumption calculation, see
"Appendix A Chassis views and technical specifications."
2. Select power supplies and identify the number of power supplies
The total maximum output power of all power supplies must be higher than the total power
consumption of the switch. For more information about available power supplies, see "Appendix
B FRUs and compatibility matrixes."
3. Verify that the power supply system at the installation site meets the requirements of the power
supplies, including the input method and rated input voltage.

5
Cooling
Plan the installation site for adequate ventilation.
•Leave at least 10 cm (3.94 in) of clearance at the inlet and outlet air vents.
•The rack for the switch has a good cooling system.
•The installation site has a good cooling system.
•Verify that the airflow design of the chassis meets the airflow design of the installation site.

Attaching slide rails and cage nuts to the rack
Installing slide rails
If the rack has slide rails, skip this section.
Before you attach slide rails to the rack, confirm the following items:
•The slide rails can support the weight of the switch. For the weights of the 7500 switches, see
"Appendix A Chassis views and technical specifications."
HP recommends that you order the HP X421 A-Series Chassis Universal 4-Post Rack Mounting Kit
(JC665A). For more information about the kit, see "Appendix B FRUs and compatibility matrixes."
•Identify the rack position for the switch. For the height and other specifications of the 7500 Switch
Series, see "Appendix A Chassis views and technical specifications."
Slide rail installation varies by rack type. The following installation procedure is for your reference only.
To install a slide rail:
1. Read the signs on the slide rail (see Table 7) to avoid making a mistake.

2. Mark the position on the rack for installing the slide rail.
a. Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes, as shown in Figure 5.
b. Each rack post requires six screws to fix the slide rail. You only need to mark the uppermost
square hole and lowermost square hole for installation.
c. Mark the square holes at the same height on the other three rack posts.
One rack unit has three holes, the middle of which is an auxiliary installation hole, and the
other two are standard installation holes. You can distinguish them by the space between each
two holes. The space between a standard installation hole and an auxiliary installation hole is
larger than that between two adjacent standard installation holes.
