Figure 4 Mounting the switch in a rack (S5110V2-52P switch)
Mounting the switch on a workbench
CAUTION:
•
Make sure the workbench is clean, sturdy, and reliably grounded.
•
Reserve a minimum clearance of 10 cm (3.94 in) around the switch.
•
Do not place heavy objects on the workbench.
If a standard 19-inch rack is not available, you can place you switch on a clean workbench.
To mount the switch on a workbench:
1.
Place the switch with bottom up, and clean the round holes in the chassis bottom with dry cloth.
2.
Attach the rubber feet to the four round holes in the chassis bottom.
3.
Place the switch with upside up on the workbench.
Grounding the switch
CAUTION:
•
Correctly connecting the grounding cable is crucial to lightning protection and EMI protection.
•
To guarantee the grounding effect, connect the switch to a grounding strip in the equipment room
using the grounding cable provided with the switch.
The power input end of the switch has a noise filter, whose central ground is directly connected to the
chassis to form the chassis ground (commonly known as PGND). You must securely connect this
chassis ground to the earth to minimize the potential for system damage, maximize the safety at the
site, and minimize EMI susceptibility of the system.
You can ground the switch in one of the following ways, depending on the grounding conditions
available at the installation site:
•
Grounding the switch by using a grounding strip
•
Grounding the switch with a grounding conductor buried in the earth ground
