To connect a VT Series terminal to an A4 Console port, use a UTP serial interface cable terminated with a DB9 female connector and a DB25 female connector and proceed as follows: 1. Connect the DB9 female connector at one end of cable to the Console port DB9 male connector on the A4 switch. (If there is a switch designated as the manager, connect to its Console port.) 2. Plug the DB25 female connector at the other end of the cable into the port labeled COMM on the VT terminal. 3. Turn on the terminal and access the Setup Directory. Set the following parameters on your terminal: When these parameters are set, the Startup screen will display. Proceed to “Connecting to the Network” on page 2‐20.

Connect the DB9 female connector at one end of the cable to the Console port DB9 connector on the A4 switch. (If there is a switch designated as the manager, connect to its Console port.) 2. Plug the DB25 male connector at the other end of the cable into the modem communications port. 3. Turn on the modem and make sure the remote modem is ON. 4. With your PC connected to the remote modem, configure your VT emulation package with the following parameters: When these parameters are set, the Startup screen will display. If the switches are in a stacked configuration, proceed to “Connecting to the Network” on page 2‐20. Connecting to the Network The following procedures cover the cable connections from the network or other devices to the A4 switch front panel ports. • “Connecting UTP Cables to RJ45 Ports” on page 2‐21 • “Installing an Optional SFP Transceiver” on page 2‐22 • “Connecting Fiber‐Optic Cables to SFP Ports” on page 2‐26 Parameter Setting Mode 7 Bit Control Transmit Transmit=9600 Bits Parity 8 Bits, No Parity Stop Bit 1 Stop Bit Connecting to Modem Connecting to the Network Enterasys A4 Fast Ethernet Switch Hardware Installation Guide 2-21 Connecting UTP Cables to RJ45 Ports The fixed RJ45 front panel 10/100 Mbps ports support Auto MDIX, which means that you can use straight‐through or crossover twisted pair cabling. To connect twisted pair segments to the switch, refer to Figure 2‐13 and proceed as follows: 1. Ensure that the device to be connected at the other end of the segment is powered on. 2. Connect the twisted pair segment to the switch by inserting the RJ45 connector on the twisted pair segment into the desired RJ45 port on the A4 switch. Figure 2-13 Connecting a UTP Cable Segment to an RJ45 Port 3. Verify that a link exists by checking that the Link/Activity LED is on (solid green or blinking green). If the Link/Activity LED is off, perform the following steps until it is on: a. Verify that the cabling being used is Category 5 or better with an impedance between 85 and 111 ohms with a maximum length of 100 meters (328 feet). b. Verify that the device at the other end of the twisted pair segment is on and properly connected to the segment. c. Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts and check the cable for continuity. 4. If a link is not established, contact Enterasys Networks. Refer to “Getting Help” on page xvii for details. Repeat all steps above until all connections have been made. Note: All fixed RJ45 front panel ports support Category 5 Unshielded Twisted Pair (UTP) cabling with an impedance between 85 and 111 ohms. Catego
