The Baseline Dual Speed Hub 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 Dual Speed Hub”on page 3.
The Baseline Dual Speed Hub 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.
To rack mount the unit:
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, as shown in the diagram.
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-in. rack and secure with suitable screws 
(not provided).
6
Reconnect all cables.
Refer to the information about LEDs given earlier in this guide to see if 
the problem can be identified and rectified. If the problem persists and 
the Baseline Dual Speed Hub still does not operate successfully, contact 
your supplier with the following information before returning the unit:
„
Product number and serial number
(printed on a label on the rear of the unit)
„
A brief description of the fault
When returning any equipment to your supplier ensure that the 
equipment is packed suitably for transit.
Some older NIC (network interface card) cards were developed 
before the standardization of the auto-negotiation protocol. 
These may cause the Baseline Dual Speed Hub to sense the 
speed of the network incorrectly. We strongly recommend that 
you install the latest versions of the NIC drivers before 
connecting your network. 3Com NIC card drivers dated before 
23/03/95 should be updated from the 3Com website.
