5. Plug the other end of the cable into the appropriate port on the other device. Some cables may
be terminated at the other end with two separate connectors, one for each fiber‐optic strand. In
this case, ensure that the transmit fiber‐optic strand is connected to the receive port and the
receive fiber‐optic strand to the transmit port.
Connecting to COM Port for Local Management
This section describes how to install a UTP straight‐through cable with RJ45 connectors and
optional adapters to connect a PC, a VT series terminal, or a modem to an Enterasys Networks
module to access Local Management. This section also provides the pinout assignments of the
adapters.
What Is Needed
The following is a list of the user‐supplied parts that may be needed depending on the connection:
• RJ45‐to‐DB9 female adapter
• UTP straight‐through cable terminated at both ends with RJ45 connectors
• RJ45‐to‐DB25 female adapter
• RJ45‐to‐DB25 male adapter
Using a UTP straight‐through cable and an RJ45‐to‐DB9 adapter, you can connect products
equipped with an RJ45 COM port to an IBM or compatible PC running a VT series emulation
software package.
Using a UTP straight‐through cable and an RJ45‐to‐DB25 female adapter, you can connect
products equipped with an RJ45 COM port to a VT series terminal or VT type terminals running
emulation programs for the VT series.
Using a UTP straight‐through cable and an RJ45‐to‐DB25 male adapter, you can connect products
equipped with an RJ45 COM port to a Hayes compatible modem that supports 9600 baud.
Connecting to an IBM PC or Compatible Device
To connect an IBM PC or compatible device, running the VT terminal emulation, to an
Enterasys Networks module COM port (
Figure 4‐12 ), proceed as follows:
1. Connect the RJ45 connector at one end of the UTP straight‐through cable to the
communications COM port on the Enterasys Networks module. (The COM port is also known
as a Console port.)
2. Plug the RJ45 connector at the other end of the UTP straight‐through cable into an
RJ45‐to‐DB9 adapter.
3. Connect the RJ45‐to‐DB9 adapter to the communications port on the IBM PC.
4. Turn on the PC and set the following parameters on your VT emulation package:
Parameter Setting
Mode 7 Bit Control
Transmit Transmit=9600
Bits Parity 8 Bits, No Parity
Stop Bit 1 Stop Bit
