Preparing for installation
The H3C S7500E-XS Switch Series includes the following models:
•S7502E-XS.
•S7504E-XS.
Safety recommendations
To avoid any equipment damage or bodily injury caused by incorrect use, 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 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 good ventilation of the equipment room and keep the air inlet and outlet vents of the switch
free of obstruction.
•Connect the yellow-green protection grounding cable before power-on.
•Make sure 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, including power modules, fan trays, and interface cards, wear an ESD wrist
strap to avoid damaging the units.
Examining the installation site
The switch must be used indoors.
Mount your switch in a rack and verify the following items:
•Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
•The rack has a good ventilation system.
•Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into the
switch from the cold aisle and exhausts to the hot aisle.
•Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the bottom
device from entering the top device.
•The rack is sturdy enough to support the switch and its accessories.
•The rack is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets the
requirements described in the following subsections.

2
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 cause problems including
loose 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 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.
Table 1 Dust concentration limit in the equipment room
Substance Concentration limit (particles/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 2.
Table 2 Harmful gas limits in the equipment room
Gas Maximum concentration (mg/m3)
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 the following ways:
•A conduction pattern of capacitance coupling.
•Inductance coupling.
•Electromagnetic wave radiation.
•Common impedance (including the grounding system) coupling.

3
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.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
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 switch is a Class 1 laser device.
Installation tools
No installation tools are provided with the switch. Prepare the following tools yourself:
•Phillips screwdriver.
•ESD wrist strap.
•Marker.

4
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 H3C for permission. Otherwise, H3C shall not be liable for any consequence caused
thereby.

Connecting the grounding cable to the chassis
CAUTION:
Select grounding points as required. The primary grounding point and auxiliary grounding point 1 are
located on the left side panel. If you use one of these grounding points, you must connect the
g
roundin
g
cable to the grounding point before you mount the switch in the rack.
H3C recommends that you use the primary grounding point or auxiliary grounding point 1 because the
grounding cable and grounding screw that come with the switch are suitable only for these two
grounding points.
To use auxiliary grounding point 2, prepare a grounding cable yourself.
This section uses the primary grounding point on the S7502E-XS switch as an example.
To connect the grounding cable to a grounding point:
1. Choose a grounding point.
2. Unpack the grounding cable and grounding screws.
You can use the cable and screws shipped with the switch only for connecting to the primary
grounding point or auxiliary grounding point 1.
3. Align the two-hole grounding lug at one end of the cable with the grounding holes of the
grounding point, insert the grounding screws into the holes, and tighten the screws with a
screwdriver, as shown in Figure 13.

Attaching the slide rails to the rack
The procedures are the same for attaching 1U and 2U slide rails to the rack. This section uses the 1U
slide rails as an example.
To attach the slide rails to the rack:
1. Identify the rack attachment position for the slide rails.
2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use
screws (user-supplied) to attach the slide rail to the rack, as shown in Figure 14.
4. Repeat the preceding steps to attach the other slide rail to the rack post on the other side.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.

Mounting the switch in the rack
This task requires two people.
To mount the switch in the rack:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Verify that the mounting brackets and chassis rails have been securely attached to the switch
chassis.
3. Verify that the slide rails have been correctly attached to the rear rack posts.
4. Install cage nuts (user-supplied) to the front rack posts and make sure they are at the same level as
the slide rails.
5. One person performs the following operations:
a. Supporting the bottom of the switch, aligns the chassis rails with the slide rails on the rack
posts.
b. Pushes the switch slowly to slide the chassis rails along the slide rails until the mounting
brackets are flush with the rack posts.
6. Another person uses screws (user-supplied) to attach the mounting brackets to the rack.
To secure the switch in the rack, make sure the front ends of the slide rails reach out of the chassis
rails.
