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.

Page 2: Installing The Switch
• 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. Installing the switch Table 1 Mounting options available for the switch Switch... - Page 3 Figure 1 Attaching mounting brackets to the switch 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. Use screws to secure the mounting brackets to the front rack posts.

Page 4: Mounting On A Workbench
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 Verify that the workbench is clean, sturdy, and reliably grounded. Place the switch bottom up, and clean the four recessed areas in the chassis bottom with a soft and dry cloth. - Page 5 Figure 3 Screw and screw anchor of the recommended size (mm) To mount the switch on a wall: 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.

Figure 4 Mounting the switch on a wall 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. -
Page 7: Connecting The Power Cord
To connect the grounding cable: 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. - Page 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: Connect the power cord to the power adapter. This step is not required for an S8G-U switch. Connect the DC connector of the power adapter to the DC power receptacle on the switch.
