Preparing for installation
H3C S1850 switch series includes the following models:
•S1850-10P
•S1850-28P
•S1850-28P-PWR
•S1850-52P
Safety recommendations
CAUTION:
The switch is a class-A device and might cause
electromagnetic interference (EMI). Take actions to prevent
EMI as required.
To avoid any equipment damage or bodily injury, read the following
safety recommendations before installation.
•Do not place the switch near water or in a damp environment.
Prevent water or moisture from entering the chassis.
•Place the switch in a clean environment. Dust buildup on the
chassis might result in electrostatic adsorption, which reduces
lifespan of the device and can cause communication failure.
•Keep the air inlet and outlet vents of the switch free of
obstruction, and do not stack switches.
•Make sure the operating voltage is stable and in the required
range.
•Before using the switch, ground it reliably by using the
grounding point on the rear panel.
2
•Before cleaning the switch, remove the power cord from the
switch. Do not clean the switch with a wet cloth or liquid.
•Do not open the chassis while the switch is operating. To avoid
damage, do not open the chassis even when the switch is
powered off.
Installing the switch
Mounting the switch in a 19-inch rack
1. Make sure the rack is reliably grounded and is stable.
2. Use screws to attach the mounting brackets to both sides of the
chassis.

(S1850-28P/S1850-28P-PWR/S1850-52P)

3. Place the switch on a rack shelf in the rack. Slide the switch into
the rack until the mounting brackets are flush against the front
rack posts and the oval holes in the brackets align with the
mounting holes in the front rack posts.
4. Use screws to secure the mounting brackets to the front rack
posts.

NOTE:
Mounting brackets are not used for bearing the weight of the
switch. A rack shelf is required on the rack to bear the switch
weight.
Mounting the switch on a workbench
1. Make sure the workbench is clean, sturdy, and reliably
grounded.
2. Place the switch bottom up, and clean the four recessed areas
in the chassis bottom with a soft and dry cloth.
3. Remove the four rubber feet from the adhesive strip provided
with the switch and attach them to the recessed areas.
5
4. Place the switch upside up on the workbench.
Mounting the switch on a wall
Only an H3C S1850-10P switch can be installed on a wall. The type
of screws used to wall-mount the switch depends on the wall type.
This section uses a concrete wall as an example.
To wall-mount the switch, you need to prepare screw anchors and
screws. The screws must be a minimum of 3 mm (0.12 in) in diameter,
and the screw head must be a minimum of 6 mm (0.24 in) in
diameter.
Figure 5 Screw anchor and screw
To install the switch on a concrete wall:
1. Drill two holes at the same height on the wall. Make sure the
spacing in between is 160 mm (6.30 in), as shown in Figure 6.
The hole depth and diameter depend on the screw anchors and
screws you use. Make sure you can push the anchors to their
full depth in the holes.

Figure 6 Hole spacing
2. Insert one screw anchor into each hole until the anchors are
flush with the wall surface.
3. Drive one screw into each screw anchor, and tighten the screw
to secure it in the wall anchor.
Leave a minimum clearance of 1.5 mm (0.06 in) between the
base of the screw head and the screw anchor so the switch can
hang on the screws securely.

4. Align the two mounting holes in the switch chassis bottom with
the two screws on the wall and hang the switch.
5. Make sure the Ethernet ports are facing downwards and the
chassis side panels are perpendicular to the ground.

Connecting cables
Connecting the console cable
To connect the switch to a configuration terminal, for example, a PC,
by using the console cable:
1. Connect the DB-9 connector of the console cable to the serial
port on the PC.
2. Connect the RJ-45 connector of the console cable to the
console port on the switch.

Connecting the grounding cable
CAUTION:
Correctly connecting the grounding cable is crucial to lightning
protection and EMI protection.
To connect the grounding cable:
1. Use a Phillips screwdriver to remove the grounding screw from
grounding hole in the rear panel of the chassis. Use the
grounding screw to attach the ring terminal of the grounding
cable to the grounding hole. Fasten the grounding screw into the
grounding hole.
2. Use needle-nose pliers to make a loop at the other end of the
cable.

3. Remove the hex nut from a grounding post on the grounding
strip. Attach the loop to the grounding post and fasten the hex
nut.
Figure 10 Connecting the grounding cable
Connecting the power cord
1. Make sure the switch is reliably grounded.
2. Connect one end of the AC power cord to the AC power
receptacle on the switch.
3. Connect the other end of the AC power cord to an AC power
source.

Installing SFP transceiver modules and
optical fibers
CAUTION:
•When you install or remove an SFP transceiver module, do
not touch the golden plating on it.
•Remove the dust plugs from an SFP transceiver module
only when you are to connect optical fibers to the module.
•Before installing an SFP module, remove the optical fibers, i
f
any, from it.
To install an SFP transceiver module and optical fibers:
1. Wear an ESD wrist strap and make sure it makes good skin
contact and is reliably grounded.
2. Pivot the bail latch of the module up. Holding the module by its
two sides, gently push the module into the slot until it has firm
contact with the slot.
Figure 12 Installing an SFP transceiver module
3. Remove the dust caps from the LC connectors of the optical
fibers, and the dust plugs from the SFP transceiver module.
4. Connect the LC connectors of the optical fibers to the
transceiver module.
