1 Preparing for installation
ESD prevention
To prevent electronic components from electrostatic discharge (ESD) damage, wear an ESD wrist
strap before working with the device or any module. Make sure the wrist strap makes good skin
contact and is reliably grounded.
Figure 1-1 Attaching an ESD wrist strap
ESD socket (with an ESD sign)
Examining the installation site
The device must be used indoors. To make sure the device operates correctly and to prolong its
service lifetime, the installation site must meet the load-bearing, temperature, humidity, cleanness,
EMI, grounding, power supply, ventilation, and space requirements. As a best practice, reserve a
minimum of 1.2 m (3.94 ft) of clearance between the device and walls or other devices. For more
information, see H3C S12500CR Switch Router Series Installation Guide.
Installation tools and equipment
No installation tools and equipment are provided with the device. Prepare them yourself as
required.

Rack requirements
Table 2-1 Rack requirements
Device dimensions
Rack requirements
•Height—1331 mm (52.40 in) (30 RU).
•Width—442 mm (17.40 in).
•Chassis depth—920 mm (36.22 in)
•Total depth—1035 mm (40.75 in)
120 mm (4.72 in) from the rack-mounting surface
of the mounting bracket to the top hood front end.
915 mm (36.02 in) from the rack-mounting
surface of the mounting bracket to the captive
screw on the fan tray at the chassis rear.
•A minimum of 1.1 m (3.61 ft) in depth
(recommended.)
•A minimum of 130 mm (5.12 in) from the
front rack post to the front door.
•A minimum of 950 mm (37.40 in) from the
front rack post to the rear door.
NOTE:
As a best practice, use a rack that has a single door at the front.
Slide rail requirements
CAUTION:
The device is heavy. Install the device at the lowest possible position.
Attach slide rails to the rack before you mount the device in the rack. You can use the LSXM1BSR
slide rails to rack-mount the device. The LSXM1BSR slide rails have an adjustment range of 630
mm (24.80 in) to 900 mm (35.43 in) and occupy 1U rack space. For information about installing the
LSXM1BSR slide rails, see H3C LSXM1BSR 1U Bottom-Support Rails Installation Guide.
Follow these guidelines for attaching the LSXM1BSR slide rails to the rack:
•
The LSXM1BSR slide rails include a left slide rail, a right slide rail, and a front plate. Make sure
all components are correctly installed.
•
Before attaching the slide rails, read signs on the slide rails to identify the right and left slide
rails and their front and rear ends. Mount the front end of the slide rails to the front rack posts.
•
Make sure the load-bearing plane of the slide rails is perpendicular to the rack posts.
Installing cage nuts for attaching mounting
brackets
Before mounting the chassis in the rack, install cage nuts on the front rack posts for attaching the
mounting brackets:
1. As shown in Figure 2-2, determine the cage nut installation holes and then mark them on the
front rack post.
2. Insert cage nuts into the marked square holes in the front rack posts.
3. Install cage nuts in the marked square holes on the front rack posts.

Mounting the device in a rack
WARNING
!
To
avoid device damage or bodily injury, follow these guidelines to lift and move the device:
•
Use the chassis handles, rather than the handles of the components (fan trays, power supplie
s,
and modules) as well as the chassis air vents, to move the chassis.
•The device is heavy. As a best practice, use a forklift to lift and move the device.

5
To mount the device in the rack:
1. Face the rear of the chassis towards the front of the rack.
2. Lift the device to a height slightly above the slide rails by holding the chassis handles.
3. Place the device on the slide rails from the front of the rack and slide the device along the
guide rails until the mounting brackets on the device touch the front rack posts tightly, as
shown by callout 2 in Figure 2-3.
WARNING
!
After
you place the device on the slide rails installed on the rack
, do not leave go of your hands
immediately because this might tip the device, damaging the device or even causing bodily injury.
4. Use M6 screws provided with the device to secure the mounting brackets to the rack posts.
As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
If the mounting holes in the mounting brackets cannot align with the cage nuts on the rack,
verify the following items:
The bottom edge of the slide rail aligns with the middle of the narrower metal area between
holes.
The cage nuts are installed in the correct holes.

Grounding the device
CAUTION:
•
Reliably grounding the device is crucial to lightning protection and EMI protection. Ground the
device reliably before you use it.
•
To guarantee the grounding effect, use the grounding cable (yellow-green grounding cable)
provided with the device.
•
Connect the grounding cable to the grounding strip in the equipment room or the grounding
point on the rack. Do not connect it to a fire main or lightning rod.
IMPORTANT:
The grounding
cable provided with the device is NEBS compliant. Connect the two-
hole grounding
lug of the grounding cable to the chassis and the ring terminal to a grounding strip.
To ground the device:
1. Unpack the grounding cable.
2. Use a screwdriver to remove the grounding screws (M6 screws) from the grounding point at
the rear of the chassis.
A grounding sign is provided with the grounding points.
3. Use the M6 screws to attach the two-hole grounding lug of the grounding cable to grounding
point on the chassis.
As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
4. Connect the ring terminal of the grounding cable to the grounding point on the rack or to the
grounding strip.

3 Installing removable components
This section describes the installation procedures for the supervisor engine units (SEUs, also called
MPUs), environment management modules, interface modules, fabric modules, fan trays, power
trays, and power supplies. For the compatibility matrix between these modules and the device
models, see H3C S12500CR Switch Router Series Hardware Reference.
WARNING
!
Long
-time exposure to strong air flow might cause discomfort. As a best practice, do not stand
close to the air outlet vents while the
device is operating. If you must be next to the device
on the air
outlet vent side for an extended period, avoid the air flow or take other protective measures.
CAUTION:
To ensure
adequate ventilation of the device, install filler panels in the unused module slots and
power supply slots.
Attaching an ESD wrist strap
To prevent electronic components from ESD damage, wear an ESD wrist strap when installing
removable components. Make sure the wrist strap makes good skin contact and is reliably
grounded.
Installing cable management brackets
The device comes with two LA/RA and eight LB/RB cable management brackets. The cable
management brackets are installed at the two sides of the chassis front panel with LA/RA cable
management brackets at the upper part and LB/RB cable management brackets at the middle and
lower parts.
Figure 3-1 Cable management brackets
The cable management brackets use the same procedure for installation at the left side and right
side of the front panel. The following procedure installs a cable management bracket at the left side.
To install a cable management bracket:
