Connecting to the Network
3-4 Installation
6. Locate the slot guides that line up with the number of the slot in which the module will be
installed. Install the module in the chassis by aligning the module circuit card between the upper
and lower metal rail guides of the desired slot, sliding it into the chassis, and locking down the
top and bottom plastic locking tabs, as shown in Figure 3-1. Take care that the module slides in
straight and properly engages the backplane connectors.
7. If the chassis in which the module is installed was powered down for the installation, turn it
back on. Check to see that the CPU LED settles at solid green after a few minutes. If the LED
does not turn solid green, see Chapter 4 for details.
3.4 CONNECTING TO THE NETWORK
This section provides the procedures for connecting twisted pair segments from the network or
other devices to the 6H203-24 or 6H253-13.
3.4.1 Connecting Twisted Pair Cables to Fixed Ports
All fixed ports of the SmartSwitches are 10/100 ports with internal crossovers. When connecting a
workstation, use a straight-through connection. When connecting networking devices, such as
another bridge, repeater, or router, use a crossover connection.
Connect a twisted pair segment to the SmartSwitch as follows:
1. Ensure that the device connected to the other end of the segment is powered ON.
2. Connect the Twisted Pair segments to the 6H203-24 or 6H253-13 by connecting the RJ21
connector cable end to the RJ21 port as shown in Figure 3-2. The connector with the cable on
it must be connected to the premises wiring with the proper cross-over or straight-through
connections as dictated by the device on the other side. All screws should be tightened on the
RJ21s to prevent bad connections. Refer to the Cabletron Systems Cabling Guide for details.
NOTE
If the 6H203-24 or 6H253-13 is being installed in a network using SmartTrunking, there
are rules concerning the network cable and port configurations that must be followed for
SmartTrunking to operate properly. Before connecting the cables, refer to the Cabletron
Systems
SmartTrunk User’s Guide
for the configuration information.
NOTE
All SmartSwitch front panel ports support Category 5 Unshielded Twisted Pair (UTP)
cabling with an impedance between 85 and 111 ohms. Category 3 cable may be used if
the connection is going to be used only for 10 Mbps.
