Preparing for installation
ESD prevention
To prevent electronic components from electrostatic discharge (ESD) damage, wear an ESD wrist
strap and make sure it makes good skin contact and is reliably grounded before you service the
switch or its components.
Figure 1 Attaching an ESD wrist strap (S12516X-AF switch)
(1) ESD jack (with an ESD sign)
Examining the installation site
The switch must be used indoors. To make sure the switch 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 clearance of 1.2 m (3.94 ft) between the switch and walls or
other devices.
For more information about the installation site requirements, see H3C S12500X-AF Switch Series
Installation Guide.
Installation tools and equipment
No installation tools and equipment are provided with the switch. Prepare them yourself as required.

Slide rail requirements
IMPORTANT:
The switch is heavy. Install the switch at the lowest possible position.
Attach the required slide rails to the rack before you mount the device in the rack. For more
information about attaching slide rails, see the rails installation guide.
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 slide rail installation positions are at the same height on the four rack posts.

NOTE:
•The LSXM1BSR slide rails include a left slide rail, a right slide rail, and a front plate. When
attaching the slide rails to the rack, make sure all accessories are correctly installed.
•Flanges of the LSVM1BSR10 slide rails are at the bottom so the slide rails do not occupy rack
space.
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 7, Figure 8, Figure 9, and Figure 10, determine the cage nut installation
holes and then mark them on the front rack post.
2. Install cage nuts in the marked square holes on the front rack posts.
For the S12516X-AF, S12512X-AF, and S12508X-AF switches, cage nuts are not needed for
the top two marked square holes on the right front rack post.
For the S12504X-AF switch, install cage nuts in all the marked square holes.

Mounting the switch in a rack
CAUTION:
•Remove fan trays, power modules, and filler panels from the switch before moving if you lift the
switch manually. Reinstall these components after installing the switch in the rack.
•Do not hold the handle of a fan tray, a power module, or a card, 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.
•After you place the switch on the slide rails, do not leave go of your hands immediately because
this might tip the switch, damaging the switch or even causing bodily injury.
To mount the switch in the rack:
1. Face the rear of the chassis towards the front of the rack.
2. Use a minimum of four people to move the switch by holding the chassis handles.
As a best practice, use a mechanical lift to lift the switch.
3. Place the switch on the slide rails from the front of the rack and slide the switch along the guide
rails until the mounting brackets on the switch touch the front rack posts tightly, as shown by
callout 2 in Figure 11.
4. Use screws provided with the switch to attach the mounting brackets to the rack posts.
For the S12516X-AF, S12512X-AF, and S12508X-AF switches, the name plate on the upper
right corner of the front panel covers two mounting screw holes on the mounting brackets.
Screws are not needed for these two mounting holes.
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 switch
CAUTION:
•Grounding the switch reliably is crucial to lightning protection and EMI protection. Ground the
switch reliably before you use it.
•Use the grounding cable (yellow-green grounding cable) provided with the switch.
•Connect the grounding cable to the earthing system in the equipment room. Do not connect it to
a fire main or lightning rod.
To connect the grounding cable to a grounding strip:
1. Unpack the grounding cable.
The grounding cable provided with the switch is compliant with the NEBS standards. The
two-hole grounding lug of the grounding cable is used for connecting the chassis. The ring
terminal of the grounding cable is used for connecting the grounding strip.
2. Remove the grounding screws from the grounding holes at the rear of the chassis.
A grounding sign is provided with the grounding holes, as shown by callout 2 in Figure 12.
3. Use grounding screws to attach the two-hole grounding lug of the grounding cable to the
chassis.
4. Connect the ring terminal of the grounding cable to a grounding post of the grounding strip,
and fasten the grounding cable to the grounding strip with the hex nut.

Installing FRUs
This section describes the installation procedures for the MPUs, LPUs, switching fabric modules,
fan trays, and power modules. For the compatibility matrix between these modules and the switch
models, see H3C S12500X-AF Switch Series Installation Guide.
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 switch is operating. If you must be next to the switch on the ai
r
outlet vent side for an extended period, avoid the air flow or take other protective measures.
CAUTION:
For good ventilation of the switch, install filler panels in empty FRU slots.
Attaching an ESD wrist strap
To prevent electronic components from ESD damage, wear an ESD wrist strap and make sure it
makes good skin contact and is reliably grounded before you install FRUs. See Figure 1 for
attaching an ESD wrist strap.
Installing MPUs
CAUTION:
•If you are not to install an MPU in an MPU slot, keep the filler panel in the slot.
•When you install an MPU, avoid damaging the connectors on the MPU.
•To prevent a filler panel from being drawn into the chassis when fan speed is high, use both
hands to grasp the filler panel by its two sides during filler panel installation and removal on an
operating switch.
Unless otherwise stated, the term "MPU" in this document refers to MPUs and cloud SEUs.
You can install one MPU, or two MPUs for redundancy on the switch. If you are to install one MPU,
install it in either of the MPU slots.
