14Rack-mounting by using front mounting brackets andmounting rail assembliesThis mounting method is applicable only to the S5130-54QS-HI switch.You can install the front mounting brackets at the port-side or power-side mounting position asneeded.This task requires two people.To install the switch in a 19-inch rack by using the front mounting brackets and mounting railassemblies:1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.2. Attach the front mounting brackets and the chassis rails to the chassis (see Figure 18):a. Unpack the front mounting brackets and the M4 screws for attaching the brackets to theswitch chassis.b. Align the round holes in the wide flange of one front mounting bracket with the screw holesin the power-side mounting position on one side of the chassis.c. Use M4 screws (supplied with the switch) to attach the mounting bracket to the chassis.d. Align one chassis rail with the screw holes in the chassis rail mounting position.e. Use M4 screws (supplied with the switch) to attach the chassis rail to the chassis.f. Repeat the proceeding steps to attach the other mounting bracket and chassis rail to theother side of the chassis.Figure 18 Attaching the front mounting brackets and chassis rails to the chassis3. Attach the slide rails to the rack:a. Identify the rack attachment position for the slide rails.b. Install cage nuts (user-supplied) in the mounting holes in the rack posts.c. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, anduse M6 screws (user supplied) to attach the slide rail to the rack, as shown in Figure 19.d. Repeat the preceding step to attach the other slide rail to the rack post on the other side.Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.
