Introduction
The Baseline 10/100 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 Baseline 10/100 Switch" on
page 3.
Rack Mounting the Units
The Baseline 10/100 Switch is 1U high and will fit a standard
19-inch rack.
CAUTION: Disconnect all cables from the unit before
continuing. Remove the self-adhesive pads from the
underside of unit, if already fitted.
1
Place the unit 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 unit (refer to the figure following step 6).

ROBLEM
Refer to the information about LEDs given earlier in this guide to
see if the problem can be identified and rectified. Here are some
common problems that can occur:
Link Status LED not lit for a port that has a connection.
There is a problem with this connection. Check that:
The device being connected to is powered on and operating
correctly.
The cable is connected at both ends.
The cable is not damaged.
If the connection is to a workstation, that the workstation's
network interface is installed and configured correctly.
All ports appear to show continual activity. There may be
broadcast storms on the network.

3
Insert the two screws supplied in the mounting kit and fully
tighten with a suitable screwdriver.
4
Repeat the two previous steps for the other side of the unit.
5
Insert the unit into the 19-inch rack and secure with suitable
screws (not provided).
6
Reconnect all cables.
Remove port connections one at a time, waiting a few seconds
between each port. If the LEDs go off after removing a port
connection, the device that was connected to that port is
introducing an excessive amount of broadcast frames to the
network (some pieces of network equipment operate by sending
out broadcast frames regularly). Refer to the documentation that
accompanies the device for information on disabling the
broadcast operation.
If the problem persists and the unit still does not operate
successfully, contact your supplier with the following information
before returning the unit:
