CHAPTER 1 INTRODUCTION Welcome to the Cabletron Systems EMC38-12 User’s Guide. This manual explains installation instructions and provides specifications for the twelve port Ethernet Media Converter (EMC). 1.1 USING THIS MANUAL Read through this manual to gain an understanding of the features and capabilities of the EMC38-12. You should have a general working knowledge of ethernet IEEE 802.3 10Base-T, and ethernet IEEE 802.
CHAPTER 1: INTRODUCTION 1.2 GETTING HELP If you need additional support related to the EMC38-12, or if you have any questions, comments, or suggestions concerning this manual, contact Cabletron Systems Technical Support: By phone ..........................(603) 332-9400 Monday-Friday; 8am - 8pm EST By CompuServe® .............GO CTRON from any! prompt By Internet mail ...............support@ctron.com 1.3 EMC38-12 OVERVIEW The EMC38-12 converts ethernet IEEE 802.3 10Base-T signals to ethernet IEEE 802.
EMC38-12 FEATURES 1.4 EMC38-12 FEATURES Automatic Transmit Port Disable The EMC38-12 automatically disables the Transmit port when its corresponding Receive port does not have a link. Full Duplex Ethernet Support All of the EMC38-12 ports support Full Duplex Ethernet provided that the device at the other end of the port supports Full Duplex Ethernet also. Full Duplex Ethernet allows the EMC38-12 to transmit and receive signals simultaneously for a 20 Megabit bandwidth through-put.
CHAPTER 1: INTRODUCTION Environmental Requirements Operating Temperature: +5° to +40° C (41° to 104° F) Non-operating Temperature: -30° to +90° C (-22° to 194° F) Operating Humidity: 5 to 95% (non-condensing) Safety and Approvals This unit meets the safety requirements of UL 1950, CSA C22.2 NO 950, and EN 60950; the EMI requirements of FCC Class A and EN 55022 Class A, VCCI Class I; and the EMC requirements of EN 50082-1.
CHAPTER 2 INSTALLATION This chapter explains how to install the EMC38-12 in a 19-inch rack and also provides requirements for installing the EMC38-12 on a tabletop or shelf. 2.1 UNPACKING THE EMC38-12 Unpack the EMC38-12 as follows: 1. Remove the shipping box material covering the EMC38-12. 2. Carefully remove the EMC38-12 from the shipping box. 3. Remove the EMC38-12 from its non-conductive bag. If you notice any signs of damage, contact Cabletron Systems Technical Support immediately. 2.
CHAPTER 2: INSTALLATION 2.2.1 Rack Mounting the EMC38-12 Before installing the EMC38-12, care must be taken to ensure that the rack used will support the unit and that the rack remains stable with the EMC38-12 installed. In order to allow for proper cooling within the rack, there must be a two inch clearance on either side of the unit. Refer to Chapter 1 for power and enviromental requirements. The following procedure explain how to install the EMC38-12 in a 19-Inch rack. 1.
INSTALLING THE EMC38-12 3. With the rack mounting brackets installed, position the EMC38-12 between the vertical frame members of the 19-inch rack and fasten it securely with the mounting screws as shown in Figure 2-2. 19-Inch Rack EMC38-12 PWR TPLINK XMT RCV FOLNK 12 11 10 9 8 7 6 5 4 3 2 1 Ethernet Media Converter WITH LANVIEW RX TX RX TX RX TX RX TX RX TX RX TX RX TX RX TX RX TX RX TX RX TX RX TX 12 11 10 9 8 7 6 5 4 3 2 1 Screws (4) Figure 2-2.
CHAPTER 2: INSTALLATION 2.3 CONNECTING THE EMC38-12 TO THE POWER SOURCE Note: The EMC38-12 has a universal power supply. This allows you to connect the EMC38-12 to power sources from 100 Vac to 125 Vac, 50-60 Hz. or 200 Vac to 240 Vac, 50-60 Hz. To connect the EMC38-12 to the power source: 1. Plug the power cord into the back panel of the EMC38-12. 2. Plug the other end of the power cord into a grounded wall outlet. 3. Verify that the PWR LED is on, this indicates that the EMC38-12 is receiving power.
CHAPTER 3 CONNECTING TO THE NETWORK This chapter outlines the procedure for connecting the EMC38-12 to your network. 3.1 CONNECTING A TWISTED PAIR SEGMENT TO THE EMC38-12 The rear panel of the EMC38-12 has a 50-pin Champ connector. The configuration outlined in this section explains how to attach a twisted pair cable to the EMC38-12 and to a 10Base-T compliant ethernet device that has a 50-pin Champ connector (e.g. Cabletron’s ELM or TPRMIM).
CHAPTER 3: CONNECTING TO THE NETWORK 2. Attach the other end of the 50-pin feeder cable to the Champ connector on the 10Base-T compliant ethernet device. 3. Check that the link LED on the 10Base-T ethernet device and the applicable TPLNK LED on the EMC38-12 are on. If the LEDs are not on, perform each of the following steps until the LEDs are on: a. Check that the 10Base-T device and the EMC38-12 have power. b. Verify the cabling between the EMC38-12 and the 10Base-T device. c.
CONNECTING A FIBER OPTIC LINK SEGMENT We recommend that you label the fiber optic cable to indicate which fiber is Receive and which is Transmit. When you buy fiber optic cable from Cabletron Systems, it is labeled so that: at one end of the cable, one fiber is labeled 1, and the other fiber is labeled 2. This pattern is repeated at the other end of the cable. If you did not purchase your cable from Cabletron Systems, be sure you label your cable as described above.
CHAPTER 3: CONNECTING TO THE NETWORK 5. Attach the fiber labeled 2 to the receive port. 6. Check that the FOLNK LED on the ECM38-12 is on. If the LED is not on, perform the following steps until it is: a. Check that the power is turned on for the device at the other end of the link. b. Verify proper “receive to transmit” connection of fiber strands between the applicable port on the module and the fiber optic device at the other end of the fiber optic link segment. c.
CHAPTER 4 USING THE LANVIEW LEDS This chapter describes how to use the LANVIEW Diagnostic LEDs to monitor EMC38-12 status and diagnose problems. EMC38-12 PWR TPLINK XMT RCV FOLNK 12 11 10 9 8 7 6 5 4 3 2 1 Figure 4-1. LANVIEW LEDS 4.1 • • 4.2 • • PWR (Power) On (Green) - Indicates that the EMC38-12 is receiving power. Off - Indicates that the unit is not receiving power. Check the input power source (circuit breakers, fuse, power cord, etc.).
CHAPTER 4: USING THE LANVIEW LEDS 4.3 • • 4.4 • • 4.5 • • RCV (Receive) On (Flashing Yellow) - Indicates that the unit is receiving data packets from the associated fiber otic port and transmitting them to the twisted pair port. The flash of the LED is pulse stretched for viewing effect. The LED may be on, but appear not to flash because of the pulse stretched viewing effect. Off - No activity.
APPENDIX A CABLE REQUIREMENTS This appendix provides cable requirements for each of the EMC38-12 ports. A.1 10Base-T TWISTED PAIR REQUIREMENTS When you connect a 10Base-T twisted pair segment to the EMC38-12, the device at the other end of the twisted pair segment must meet IEEE 802.3 10Base-T specifications. Your 10Base-T twisted pair segment must meet the following requirements. Segment Length The IEEE 802.
APPENDIX A: CABLE REQUIREMENTS A.2 10Base-FL MULTIMODE FIBER REQUIREMENTS When you connect a 10Base-FL Multimode Fiber segment to the EMC38-12, the device at the other end of the fiber segment must meet IEEE 802.3j 10Base-FL specifications. Your 10Base-FL Multimode Fiber segment must meet the following requirements. Segment Length The IEEE 10Base-FL standard requires that devices be able to transmit from 0 to at least 2000 meters (6561 feet) per segment of fiber optic cable.
