Figure 11 Installing the chassis in the rack (S7506X-PoE switch)
NOTE:
If the screw holes in the mounting brackets cannot align with the cage nuts on the rack, verify that
the bottom edge of the slide rail aligns with the middle of the narrowest metal area between holes
and that the cage nuts are installed in the correct holes.
Grounding the switch
CAUTION:
Correctly grounding the switch is crucial to lightening protection and EMI prevention. Before you use
the switch, make sure you have grounded it reliably.

Connecting the grounding cable to a grounding strip

CAUTION:
• Connect the grounding cable to the earthing system in the equipment room. Do not connect it to
a fire main or lightning rod.
• To guarantee the grounding effect, use the grounding cable provided with the switch. The
grounding cable uses a two-hole lug for connecting the chassis and a ring terminal for connecting
the grounding strip. It is compliant with the NEBS standard.
When a grounding strip is available at the installation site, you can ground the switch by connecting
the grounding cable to the grounding strip.
To connect the grounding cable to a grounding strip:
1. Unpack the grounding cable.
2. Remove the grounding screws from the grounding holes at the rear of the chassis.
3. Use grounding screws to attach the two-hole grounding lug of the grounding cable to the
chassis.
4. Connect the other end (ring terminal) of the grounding cable to the grounding post of the
grounding strip, and fasten the grounding cable to the grounding strip with the hex nut.
