Rack-Mounting The Switch By Using Front And Rear Mounting Brackets - H3C S5170-EI Series Installation Manual

Rack-mounting the switch by using front and rear mounting
brackets
The installation procedures are the same for the S5570S-28S-HPWR-EI, S5570S-54S-PWR-EI, and
5570S-30MS-UPWR-EI. The following uses the S5570-28S-HPWR-EI as an example.
Attaching the front mounting brackets and shoulder screws to the switch
The switch provides two installation positions on its side for the front mounting brackets. One is near
the power supply side and one is near the port side. The following procedure attaches the front
mounting brackets to the installation position near the port side. The power supply-side mounting is
similar.
To attach the front mounting brackets and shoulder screws to the switch:
1. Wear an ESD wrist strap. Make sure the strap makes good skin contact and is reliably
grounded.
2. Align the round holes in the wide flange of one front mounting bracket with the screw holes in
the chassis. See
3. Use M4 screws (supplied with the switch) to attach the mounting bracket to the chassis. As a
best practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten the M4 screws.
4. Repeat the preceding two steps to attach the other mounting bracket to the chassis.
5. Unpack the shoulder screws and attach them to the chassis. As a best practice, use a torque of
12 kgf-cm (1.18 Nm) to fasten the shoulder screws.
Two installation positions as red-marked in
one as required.

Attaching the rear mounting brackets to the rack
1. Determine the switch installation position in the rack.
2. Install cage nuts (user-supplied) in the rear rack posts. Make sure the corresponding cage nuts
on the left and right rear rack posts are at the same height.
3. Orient the rear mounting brackets with the wide flange inside or outside the rack as required.
4. Use M6 screws (user-supplied) to attach the rear mounting brackets to the rear posts, as shown
in Figure
Do not fully tighten the M6 screws before mounting the switch in the rack.

9. As a best practice, use a torque of 30 kgf-cm (2.94 Nm) to fasten the M6 screws.
