ETUP
Water or moisture cannot enter the case of the unit.
Temperature must be within the range of 0 to 40 degrees Celsius.
Air-flow around the unit and through the vents in the side of the
case is not restricted. You should provide a minimum of 25mm
(1-inch) clearance.
No objects are placed on top of the unit.
Units are not stacked more than four high if the Switch is
free-standing.
The connectors, supported media types, and maximum distances for
the Switch 9000 are described in Chapter 1.
The Switch 9000 can be mounted in a rack, or placed free-standing on
a tabletop.
The Switch 9000 is 2U high and will fit in most standard 19-inch racks.
The Switch should only be used in a rack if it is mounted on runners, a
shelf, or a tray to support the weight. The rack mount kits alone are
not sufficient to support the weight of the Switch.
CAUTION: The rack mount kits must not be used to suspend the
Switch from under a table or desk, or attach it to a wall.
To install the mounting brackets on the Switch, follow these steps:
1 Place the Switch the right way up on a hard flat surface, with the front
facing toward you.
2 Remove the existing screws from the sides of the chassis.
3 Locate a mounting bracket over the mounting holes on one side of the
unit.
4 Insert the four screws and fully tighten with a suitable screwdriver, as
shown in Figure 2-1.
