Preparing for installation
H3C Mini Unmanaged Ethernet Switches include the following
models:
• H3C Mini S8G-U (S8G-U).
• H3C Mini S9-PWR (S9-PWR).
• H3C Mini S16G-U (S16G-U).
• H3C Mini S24-U (S24-U).
• H3C Mini S24G-U (S24G-U).
Safety recommendations
To avoid any equipment damage or bodily injury, read the following
safety recommendations before installation. The recommendations
do not cover every possible hazardous condition.
• 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 in the required range.
• Before using the switch, make sure the grounding cable of the
switch is correctly connected.
• 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.
2
• To avoid damage caused by improper operation, do not open
the chassis even if the switch is powered off.
NOTE:
The switch is a class-A device and might cause electromagnetic
interference (EMI). Take actions to prevent EMI when
necessary.

Mounting in a 19-inch rack
No mounting brackets and screws are provided with the switch.
Prepare them yourself.
To install the switch in a 19-inch rack:
1. Verify that the rack is reliably grounded and is stable.
2. Use screws to attach the mounting brackets to both sides of the
chassis.
3
Figure 1 Attaching mounting brackets to the switch
3. Place the switch on a rack shelf in the rack. Push the switch in
until 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 used only for securing the switch to the
rack. A rack shelf on the rack is required to bear the switch
weight.
Mounting on a workbench
1. Verify that 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. Attach the rubber feet to the recessed areas.
4. Place the switch upside up on the workbench.
Mounting on a wall
You can use pan-head screws and the mounting holes in the switch
bottom to mount the switch on a wall.
No screws and screw anchors are provided with the switch. Prepare
them yourself. The following figure shows the screw and screw
anchor of the recommended size.
5
Figure 3 Screw and screw anchor of the recommended size
(mm)
To mount the switch on a wall:
1. Determine the hole diameter and depth based on the screw and
screw anchor size. Make sure the screw anchor can be inserted
into the hole and seated flush with the wall and the screw can be
fastened securely into the anchor.
If you use screws and screw anchors of the recommended size,
the hole diameter is 5 mm (0.20 in).
2. Drill two holes spacing 90 mm (3.54 in) on the wall. Make sure
the two holes are on a horizontal line.
3. Fasten a screw anchor into each hole and make sure the anchor
is flush with the wall.
4. Insert a screw into each anchor, leaving a minimum of 2.5 mm
(0.10 in) between the screw head and wall for mounting the
switch
5. Align the two mounting holes in the switch bottom with the
screws and hang the switch on the screws.

Connecting cables
Connecting the grounding cable
CAUTION:
Correctly connecting the grounding cable is crucial to lightning
protection and EMI protection.
The switch is not provided with a grounding cable. Prepare one
yourself.
7
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 5 Connecting the grounding cable
Connecting the power cord
Connecting the AC power cord
The S16G-U, S24-U, and S24G-U switches support AC power input.
To connect the AC 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.
8
Connecting a power adapter
The S8G-U and S9-PWR switches support power input by using a
power adapter.
To connect the power adapter:
1. Connect the power cord to the power adapter.
This step is not required for an S8G-U switch.
2. Connect the DC connector of the power adapter to the DC
power receptacle on the switch.
3. Connect the plug of the power adapter to an AC power source.

NOTE:
The three-position DIP switch can shift the switch functions as
follows:
• 标准交换—Enable flow control and downshift.
• 网络克隆—Disable flow control and enable downshift.
• 汇聚上联—Enable flow control, downshift, and uplink port
aggregation. (Ports 15 and 16 on the S16G-U and ports 23
and 24 on the S24G-U are uplink ports.)
