Installation guide

NOTE:

 HP recommends that you use the primary grounding point or auxiliary grounding point 1, because the grounding

cable and grounding screw provided with the switch are applicable only to these two grounding points.

 To use auxiliary grounding point 2 on the HP 5900AF-48XG-4QSFP+ switch, you must prepare a grounding cable

yourself. The connection method is the same as connecting to the other two grounding points.

Grounding the switch by using the AC power cord

If the installation site has no grounding strips, you can ground an AC-powered switch through the PE wire of

the power cord, but must make sure:

 The power cord has a PE terminal.

 The ground contact in the power outlet is securely connected to the ground in the power distribution

room or on the AC transformer side.

 The power cord is securely connected to the power outlet.

NOTE:

 If the ground contact in the power outlet is not connected to the ground, report the problem and reconstruct the

grounding system.

 To guarantee the grounding effect, use the grounding cable provided with the switch to connect to the grounding

strip in the equipment room.
