Attaching the Switch to a Rack or Cabinet
About this task
To attach a switch to a two-post rack, 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.
NoteThe X440-G2 and X620 switches can be front-mounted or mid-mounted to a two-post rack only. They cannot be attached to a four-post rack or cabinet.
On one side of the switch, set a
mounting bracket against the switch housing.
Set the flange even with the front panel of the switch – or, if you are mid-mounting the switch in a two-post rack, set the flange toward the back of the switch.The following figures illustrate how to attach the brackets for two common mounting options.
NoteFor some switch models, only short mounting brackets are provided.
- Use the small bracket-mounting screws (provided) to secure the bracket to the switch housing.
- Repeat step 1 and step 2 to attach the other bracket to the other side of the switch.
Slide the switch into the
equipment rack or cabinet.
Sliding the Switch into the Rack shows an example of a mid-mount installation.
- Secure the mounting bracket
flanges to the rack, using screws that are appropriate for the rack.
(Rack-mounting screws are not provided.)
If you are mounting the switch
in a four-post rack or a cabinet, secure the rear mounting brackets
Otherwise, skip to step 7.
At the rear of the rack
or cabinet, for each side, slide the rails between the two rows of pegs
on either side of the switch.
NoteIt is best practice to extend the rear rails no more than 33 inches (83cm) from the front of the chassis.
Secure the rear mounting
brackets to the rack posts using suitable screws.
Be sure the switch is level.
- At the rear of the rack or cabinet, for each side, slide the rails between the two rows of pegs on either side of the switch.
If a grounding lug is present,
ground the switch.
For X450-G2 series switches, ground the switch as follows:
- At one end of the wire, strip the insulation to expose 1/2 inch (12 mm) of bare wire.
- Identify the grounding lug on the back of the switch.
- Insert the stripped wire into the grounding lug.
- Using a straight-tip torque screwdriver, tighten the retaining screw to 20 in‑lb (2.25 N m).
- Connect the other end of the wire to a known reliable earth ground point at your site.
What to do next
After the switch is secured to the rack or cabinet, install optional components using the instructions in Installing Optional Components.
Then, if your switch does not have an installed power supply, install one or two power supplies using the instructions in Installing Internal Power Supplies.
To determine which internal power supplies are compatible with your switch, see Replaceable Internal Power Supplies.
