1 Preparing for installation
ESD prevention
To prevent electrostatic discharge (ESD) damage, always wear an ESD wrist strap when working
with the switch or any component. Make sure the wrist strap makes good skin contact and is reliably
grounded.
Figure 1-1 Attaching an ESD wrist strap
(1) ESD jack (with an ESD sign)
Examining the installation site
The switch must be used indoors. To ensure correct operation of the switch and to prolong its
service lifetime, the installation site must meet the load-bearing, temperature, humidity, cleanliness,
EMI, grounding, power supply, ventilation, and space requirements. Reserve a minimum clearance
of 1.2 m (3.94 ft) between the switch and walls or other devices.
For more information, see H3C S12500X-2L Switch Installation Guide.
Installation tools and equipment
No installation tools and equipment are provided with the switch. Prepare them yourself as required.

NOTE:
Load
-bearing flanges of the LSVM1BSR10 slide rails are at the bottom so the slide rails do not
occupy rack space.
Installing slide rails
1. Read the signs on the slide rails to identify the front and rear ends of the slide rails.
2. As shown in Figure 2-2, mark the position on the rack post for installing the slide rail.
a. Insert the locating pin at the bottom of the slide rail into the lowest square hole within the
2U space on the rack post.
b. Mark the uppermost square hole and lowermost square hole for installation on the rack
post.
c. Mark the square holes at the same height on the other three rack posts. Make sure the
slide rail installation positions are at the same height on the four rack posts.
3. Install cage nuts in the marked square holes on each rack post except for the uppermost
marked square holes on the front rack posts. See callout 3 in Figure 2-2.
4. Perform the following task to secure the slide rail to the rack posts:
a. Align the installation holes on the front end of the slide rail with the cage nuts on the front
rack post.
b. Compress the slide rail, making sure the locating pins at both ends of the slide rail are
inserted into the lowest square holes within the 2U space on the rack posts.
c. Use the provided M6 screws to secure the slide rail to the rack posts.
The recommended torque is 30 kgf-cm (2.94 Nm).
Use only the two lowermost cage nuts on each front rack post. Reserve the uppermost cage
nut on each front rack post for attaching mounting brackets.

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 by performing the following steps:
1. As shown in Figure 2-3, 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. If you have installed
screws in the two uppermost holes, remove them first.

Mounting the switch in a rack
CAUTION:
•
Hold the chassis handles to move the switch. Do not hold the handle of a fan tray, a power
supply, or a module 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.
•Do not place your hand into any slot when you move the chassis.
To mount the switch in the rack:
1. Face the rear of the chassis towards the front of the rack.
2. Move the switch by holding the chassis handles.
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 1 in Figure 2-4.
4. Use the provided M6 screws provided with the switch to attach the mounting brackets to the
rack posts. The recommended torque is 30 kgf-cm (2.94 Nm).
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.
A grounding strip at the installation site is required to ground the switch.
To connect the grounding cable to the 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 1 in Figure 2-5.
3. Use grounding screws to attach the two-hole grounding lug of the grounding cable to the
chassis.
The recommended torque is 30 kgf-cm (2.94 Nm).
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.
