Choosing a Suitable
Site
The Switch is suited for use in a network room, or telecommunications
room, where it can be mounted in a standard 19-inch equipment rack, or
free-standing. Alternatively, the Switch can be rack-mounted in a wiring
closet or equipment room. A rack-mounting kit, containing two
mounting brackets and six screws is supplied with the unit.
CAUTION:
Ensure that the ventilation holes are not obstructed.
When deciding where to position the Switch, ensure that:
Cabling is located away from:
sources of electrical noise such as radios, transmitters and
broadband amplifiers.
power lines and fluorescent lighting fixtures
The Switch is accessible and cables can be connected easily.
Water or moisture cannot enter the case of the Switch.
Air-flow is not restricted around the Switch or through the vents in the
side of the Switch. 3Com recommends that you provide a minimum of
25 mm (1 in.) clearance.
Air flow around the Switch does not exceed 40
°C
(104
°
F).
If the Switch is installed in a 19-inch rack or closed assembly its local air
temperature may be greater than room ambient temperature.
The air is as free from dust as possible.
17702ua.bk Page 18 Friday, April 6, 2001 3:31 PM
Rack-mounting 19
The unit is installed in a clean, air conditioned environment.
No more than four Switch units are placed on top of one another, if
the units are free-standing.
Ensure there is adequate clearance at the front of the unit to ensure
that the fibers are not damaged as they have a restricted bend radius.
Rack-mounting
The Switch 4900 SX is 1.5U and will fit in most standard 19-inch racks.
However, as each Switch requires a shelf or runner to support its weight,
you will need to allow a 2U space within the rack for each Switch.
WARNING:
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. The rack
mount kits must not be used to suspend the Switch from under a table or
desk, or attach it to a wall.
CAUTION:
You must use a full depth shelf or support that will not
obstruct the air flow through the side panels of the Switch 4900 SX.
CAUTION:
Disconnect all cables from the Switch before continuing.
Remove all self adhesive pads from the underside of the Switch if they
have been fitted.
To rack-mount your Switch:
1
Place the Switch the right way up on a hard flat surface, with the front
facing towards you.
2
Locate a mounting bracket over the mounting holes on one side of the
Switch, as shown in Figure 3
.

THE

WITCH
You must use the screws supplied with the mounting brackets. Damage
caused to the unit by using incorrect screws invalidates your warranty.
3
Insert the three screws and tighten with a suitable screwdriver.
4
Repeat steps 2 and 3 for the other side of the Switch.
5
Insert the Switch into the 19-inch rack and secure with suitable screws
(not provided). Ensure that ventilation holes are not obstructed.
6
Connect network cabling.
Placing Units On
Top of Each Other
If the Switch units are free-standing, up to four units can be placed one
on top of the other. If you are mixing a variety of SuperStack
®
3 Switch
and Hub units, the smaller units must be positioned at the top.
If you are placing Switch units one on top of the other, you must use the
self-adhesive rubber pads supplied. Apply the pads to the underside of
each Switch, sticking one in the marked area at each corner. Place the
Switch units on top of each other, ensuring that the pads of the upper
unit line up with the recesses of the lower unit.
The Power-up
Sequence
The following sections describe how to get your Switch 4900 SX
powered-up and ready for operation.
WARNING:
If you are connecting the Switch 4900 SX to a Type 3 Power
Module, read the Safety Information section in the Type 3 Power Module
User Guide.
Powering-up the
Switch 4900 SX
Use the following sequence of steps to power-up the Switch.
1
Plug the power cord into the power socket at the rear of the Switch.
2
Plug the other end of the power cord into your power outlet.
The Switch powers-up and runs through its Power On Self Test (POST),
which takes approximately 10 seconds.
