Attaching the mounting brackets and chassis rails to the
chassis
1. Place the wide flange of the mounting bracket against the chassis side panel. Align the
mounting bracket installation holes with the appropriate screw holes in the chassis. Use the
provided M4 screws to attach the mounting bracket to the chassis (recommended torque: 12
kgf-cm).
{ To install the mounting brackets at the port-side mounting position, see Figure 22, Figure
23, Figure 24, Figure 28, Figure 30, and Figure 32.
Use four inst
allation holes to secure the mounting brackets to the S6850-56HF, S6850-2C,
and S9850-4C switches. Use three installation holes to secure the mounting brackets to the
S9850-32H switch.
{ To install the mounting brackets at the power module-side mounting position, see Figure
25, Figure 26, Figure 27, Figure 29, Figure 31, and Figure 33.
Use four in
stallation holes to secure the mounting brackets to the switch.
2. Determine the installation position of the chassis rails based on the position of mounting
brackets and the distance between the front and rear rack posts.
