The bracket orientation and the screws you use depend on whether you are attaching the brackets for 19-, 23-, or 24-inch telco rack-mounting:
•
For 19-inch telco rack-mounting, use the supplied Phillips flat-head screws to attach the long side of the bracket to the switch.•
For 23- or 24-inch telco rack-mounting, use the supplied Phillips truss-head screws to attach the short side of the bracket to the switch.Place the switch on a level surface, and use two of the supplied Phillips flat-head or truss-head screws to attach a mounting bracket to each side of the switch. Secure all four screws tightly, but do not overtighten them.
The following sections show how to attach only one bracket to one side of the switch. Follow the same steps to attach the second bracket to the opposite side of the switch.
