• Screws for attaching mounting hardware to the switch housing.
You need the following additional tools and equipment. These are not provided with
your switch.
• Rack mounting screws: eight for a four-post installation; four for other installations.
The size of the screws will vary based on the rack system you are using.
• Screwdriver for securing the rack mounting screws.
• #2 Phillips screwdriver to attach bracket screws that are provided with the switch.
Use a magnetic screwdriver.
• AC power cord. For switches with removable AC power supplies, a separate
power cord is needed for each installed power supply. The cord must meet the
requirements listed in Power Cord Requirements for AC-Powered Switches and AC
Power Supplies on page 87.
• ESD-preventive wrist strap for installing optional ports at the back of the switch.
Attach the Switch to a Rack or Cabinet
To attach a switch to a four-post rack or a cabinet, follow these steps.
Take care to load the rack so that it is not top-heavy. Start installing equipment at the
bottom and work up.
1. Attach a rack ear to one side of the switch, screwing it into the holes so that the
ange (ear) is ush with the front of the switch for a front mount.
If you are mid-mounting the switch, set the ange toward the back of the switch.
The following gures illustrate how to attach the brackets for two common
mounting options.
• Figure 20 shows a mid-mount conguration using a short mounting bracket.
• Figure 21 shows a front-mount conguration using a short mounting bracket.
