3Com 2250-SFP, 2226-SFP, 2426-PWR manual Rack-Mounting or Free-Standing, Using the Mounting Kit

It is always good practice to wear an anti-static wrist strap when installing network equipment, connected to a ground point. If one is not available, try to keep in contact with a grounded rack and avoid touching the unit's ports and connectors, if possible. Static discharge can cause reliability problems in your equipment.

Rack-Mounting or Free-Standing

The unit can be mounted in a 19-inch equipment rack using the mounting kit, or it can be free standing. Do not place objects on top of the unit or stack.

CAUTION: If installing the Switch in a free-standing stack of different size Baseline or Superstack 3 units, the smaller units must be installed above the larger ones. Do not have a free-standing stack of more than six units.

Using the Mounting Kit

The Switch is supplied with two mounting brackets and four screws. These are used for rack mounting the unit. When mounting the unit, you should take note of the guidelines given in “Positioning the Switch” on page 18.

The Switch is 1U (1.7 inches) high and will fit in a standard 19-inch rack.

CAUTION: Disconnect all cables from the unit before continuing. Remove the self-adhesive pads from the underside of the unit, if already fitted.
