3.5 CONNECTING TO THE NETWORK
This section provides the procedures for connecting twisted pair and fiber
optic segments from the network or other devices to the 2H23-50R or
2H33-37R.
CONN 1 through CONN 4 (2H23-50R) or CONN 1 through CONN 3
(2H33-37R) each have 12 UTP connections via a 50-pin RJ21 connector.
If a port is to operate at 100 Mbps, each pair in a cable must be
Category 5 compliant with an impedance of 85 to 111 ohms.
Slots 5 and 6 of the 2H23-50R support FE-100TX, FE-100FX, or
FE-100F3 Fast Ethernet Interface Modules.The FE-100TX has an RJ45
connector for a UTP cable connection. The FE-100FX and FE-100F3
have SC connectors for fiber optic cable connections.
To make twisted pair connections to CONN 1 through CONN 4
(2H23-50R) or CONN 1 through CONN 3 (2H33-37R), refer to
Section 3.5.1 .
To make a twisted pair connection to an FE-100TX in slot 5 or 6 of a
2H23-50R, refer to
Section 3.5.2 .
To make a fiber optic cable connection to an FE-100FX or FE-100F3 in
slot 5 or 6 of a 2H23-50R, refer to
Section 3.5.3 .
Refer to the associated High Speed Interface Module user’s guide to make
connections to an optional High Speed Interface Module installed in the
HSIM slot of a 2H33-37R.
NOTE
If the device is being installed in a network using
SmartTrunking, there are rules concerning the cable
connections and port configurations that must be followed for
SmartTrunking to operate properly. Before connecting the
cables, refer to the Cabletron Systems
SmartTrunk User’s
