Attaching mounting brackets and chassis rails to the switch
IMPORTANT:
•
The S9855-64D switch uses 2U bottom support rails for rack mounting. You are not required to
attach chassis rails to it.
•
M4 screws are used to attach mounting brackets and chassis rails to the switch. As a best
practice, use a torque of 12 kgf-cm (1.18 Nm) to fasten M4 screws.
To attach 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 screw holes in the side panel. Then use the
provided M4 screws to attach the mounting bracket to the chassis.
To install the mounting brackets at the port-side mounting position, see
To install the mounting brackets at the power supply-side mounting position, see
For the S9855-48CD8D and S9855-24B8D switches, use the four installation holes at the
narrow side of the mounting brackets for installation.
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.
