Preparing for installation
The HPE FlexNetwork 7500 Switch Series includes the following models:
•7502.
•7503.
•7503-S.
•7506.
•7506-V.
•7510.
Safety recommendations
To avoid possible bodily injury and equipment damage, read the safety recommendations in this
chapter carefully before installing an HPE
7500 switch. 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 you have adopted anti-slip measures.
•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 moist floors.
•Locate the emergency power-off switch in the room before installation. Shut the power off at
once in case accident occurs.
•Remove all the external cables (including power cords) before moving the chassis.
•Do not work alone when the switch has power.
•Always verify that the power has been disconnected.
Handling safety
CAUTION:
•When moving the switch, hold the handles at both sides of the chassis.
•Do not hold the handle of a fan tray, a power supply, or the back cover of the chassis, or the air vents of the
chassis to move the switch. Any attempt to carry the switch with these parts might cause equipment
damage or even bodily injury.
To move an HPE 7500 switch:
•Remove all the external cables (including the power cords) before moving the chassis.

2
•Use a minimum of two people to move the switch, and use a mechanical lift if necessary.
•Move the switch carefully.

To prevent the electric component from being damaged by the electrostatic discharge (ESD), adhere
to the following requirements:
•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 reliably grounded when installing pluggable
modules. 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 modules in an ESD bag.
Laser safety
WARNING!
Do not stare into any fiber port or view directly with non-attenuating optical instruments when the
switch has power. The laser emitted from the fiber port might hurt your eyes.
The HPE 7500 switches are class 1 laser products.
Examining the installation site
The HPE 7500 switches can only be used indoors. To ensure correct operation and long service life
of your switch, the installation site must meet the requirements in this section.
Weight support
Evaluate the floor loading as compared to the actual weight of the switch and its accessories (such
as rack, chassis, modules, and power supplies, and make sure the floor can support the weight of
the rack and the switch chassis.
IMPORTANT:
When evaluating the floor loading, consider switch capacity expansion (for example, installing a
new module) in the future.
Temperature
CAUTION:
If condensation appears on the switch when you move it to a high-temperature environment, dry the
switch before powering it on to avoid short circuits.
To ensure the correct operation of the switch, ensure that the room temperature meets the
requirements described in Table 1.

Table 1 Temperature requirements
Temperature Range
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 2.
•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.
Table 2 Humidity requirements
Humidity Range
Operating humidity (noncondensing) 5%RH to 95%RH
Storage humidity (noncondensing) 5%RH to 95%RH
Cleanliness
Mechanically active substances buildup on the chassis might result in electrostatic adsorption, which
causes poor contact of metal components and contact points. 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.
•Electromagnetic wave radiation.
•Common impedance (including the grounding system) coupling.
To prevent EMI, perform the following tasks:
•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 to make sure the EMI levels do not exceed the compliant range.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
•To prevent signal ports from getting damaged by over-voltage or over-current caused by
lightning strikes, only route interface cables indoors.
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. For more information about the grounding methods of the
7500 switches, see "Installing the switch."
Power
Perform the following steps to satisfy the power supply requirements of the 7500 switches:
1. Calculate the total power consumption
The total power consumption of a 7500 switch depends on module type and quantity and fan
tray power consumption. If the switch provides PoE power, the total power consumption also
depends on PoE power consumption. For more information about the total power consumption
of the 7500 switches, see "Appendix A Chassis views and technical specifications."
2. Select power supplies according to the total power consumption
To ensure correct operation of the switch, make sure the maximum output power of the power
supply that supplies power to the switch is higher than the total power consumption of the
switch. After determining the total power consumption of the switch, you can select appropriate
power supplies according to the total power consumption. For more information about the
optional power supply models, see "Appendix B FRUs and compatibility matrixes."
3. Verify that the power supply system on the installation site satisfies the input requirements of
the power supplies and parameters such as rated voltage.
Cooling
For adequate heat dissipation, plan the installation site according to the airflow of your switch, and
adhere to the following requirements:
•Leave a clearance of a minimum of 10 cm (3.94 in) around the air inlet and outlet vents.
•The rack for installing the switch has a good cooling system.
•The installation site has a good cooling system.

Space
For easy maintenance, follow these guidelines:
•Reserve a minimum of 1 m (3.28 ft) of clearance between the rack and walls or other devices.
•The equipment room is a minimum of 3 m (9.84 ft) high.
•The dimensions of the rack are sufficient for the chassis. For more information about chassis
specifications, see "Appendix A Chassis views and technical specifications."

multiple switches on the rack, mount the heaviest switch at the bottom of the rack.
Attaching slide rails and cage nuts to the rack
Installing slide rails
Before installing the switch to the rack, install slide rails to the rack. If the rack has slide rails, skip this
section.
Before installing the slide rails, verify that 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."
As a best practice, order the HPE X421 A-Series Chassis Universal 4-Post Rack Mounting Kit
(JC665A). For more information about the kit, see "Appendix B FRUs and compatibility matrixes."
Make sure the rack meets the following requirements:
•For all 7500 models, there is a minimum of 100 mm (3.94 in) of clearance between the front
rack posts and the front door for accommodating the cable management brackets.
•For the 7502, there is a minimum of 440 mm (17.32 in) of clearance between the front rack
posts and the rear door for accommodating the chassis and power cord deployment.
Position the chassis of the 7500 switches according to their heights. For the specifications of the
7500 switches, see "Appendix A Chassis views and technical specifications."
The slide rail installation procedure 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 rails (see Table 7) to avoid installation mistakes.

Table 7 Description for signs on the slide rails
Sign Meaning Remarks
F/L Front end of the left slide rail Mount this end to the front left rack post.
F/R Front end of the right slide rail Mount this end to the front right rack post.
2. Mark the position on the rack for installing the slide rail.
{Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes on a rack post, as shown in Figure 5.
{Each rack post requires six screws to secure the slide rail. You only need to mark the
uppermost square hole and lowermost square hole for installation.
{Mark the square holes at the same height on the other three rack posts.
NOTE:
One rack unit has three holes, the middle of which is an auxiliary installation hole, and the othe
r
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 large
r
than the space between two adjacent standard installation holes.
