NOTE:
To rack-mount the HP 5930-4Slot/HP 5930-4Slot TAA switch by using 2U high mounting brackets and
slide rails, use two screws and two cage nuts to attach each mounting bracket to the rack. Determine the
screw installation positions based on the distances between the square holes on the rack posts. The screw

Grounding the switch
WARNING!
Correctly connecting the switch grounding cable is crucial to lightning protection and EMI protection.
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 so the faradism and leakage electricity can be safely released to the earth to
minimize EMI susceptibility of the switch.
You can ground a switch by using a grounding strip at the installation site or the AC power cord
connected to the switch.
NOTE:
The power and grounding terminals in this section are for illustration only.
Grounding the switch with a grounding strip
WARNING!
Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire
main or lightning rod.
If a grounding strip is available at the installation site, connect the grounding cable to the grounding
strip.
To connect the grounding cable:
1.
Attach the two-hole grounding lug at one end of the grounding cable to a grounding point on the
switch chassis. For more information, see
2.
Remove the hex nut of a grounding post on the grounding strip.
3.
Attach the ring terminal at the other end of the grounding cable to the grounding post on the
grounding strip, and secure the ring terminal to the grounding post with the hex nut.
