Connecting The Grounding Cable To The Chassis - H3C S6850-56HF-CP Manual

Figure2-16 Attaching the mounting brackets and chassis rails to the LS-6850-56HF-CP
switch (power module-side mounting position for the mounting brackets, super-short slide
rails, chassis rails reaching out of the chassis)
NOTE:
• Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.
• You can use super-short slide rails and chassis rails to rack-mount the switch. Based on the rack
depth, install the chassis rails with the chassis rails not reaching out of the chassis, as shown in
Figure2-13
Figure2-16.
• To install the mounting brackets at the port-side mounting position, use the four screw holes
nearest to the port side. To install the mounting brackets at the power module-side mounting
position, use the four screw holes nearest to the power module side.

Connecting the grounding cable to the chassis

IMPORTANT:
• If the grounding cable length or terminal type cannot meet your requirement, make an applicable
grounding cable or contact H3C Support.
• If you use a grounding point on the side panel to ground the switch, connect the grounding cable
to the grounding point before installing the switch in the liquid-cooled rack.
The primary grounding point and auxiliary grounding point are on the left side panel. Both grounding
points support a grounding cable that has a single-hole lug or dual-hole lug. Use M5 grounding
screws to attach the grounding cable to the switch. If you install the mounting brackets at the port
side, connect the grounding cable to the grounding point at the port side.
To connect the grounding cable:
1. Choose a grounding point as required.
2. Unpack the grounding cable and grounding screws.
3. Use the grounding screws to attach the grounding lug of the grounding cable to the grounding
holes at the grounding point. Use a screwdriver to fasten the screws. See
Figure2-18.
As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the grounding screws.
