EMM-E6 Installation Guide 2-1 ICH1Book Page 2 Tuesday, August 6, 1996 3:06 PM Chapter 2: Controls and Indicators Reset Switch The recessed reset switch re-initializes the EMM-E6 processor. The activation of this switch will not initialize Non-Volatile Random Access Memory (NVRAM) where the EMM-E6 stores configuration and management parameters. The reset switch may be pressed with the point of a pencil or pen. Once pushed in, the EMM-E6 will re-initialize itself. LANVIEW LEDs The EMM-E6 incorporates the LANVIEW status monitoring and diagnostic system. LANVIEW LEDs can help diagnose many problems, such as a fault in network cabling. LANVIEW LEDs are identified in Section 2.3, LANVIEW LEDS. EPIM (Ethernet Port Interface Module) Slot The EPIM slot is a covered opening in the EMM-E6 faceplate that can be configured with an optional EPIM module. Serial Ports The EMM-E6 faceplate provides two serial communications ports for the connection of out-of-band management devices. BRIM (Bridge/Router Interface Module) Slots The BRIM slot is a covered opening in the faceplate that can be configured with a BRIM module. 2.2 INTERNAL COMPONENTS The components listed in the following entries are all hidden inside the MMAC chassis when the EMM-E6 has been installed. These components may be located by removing the EMM-E6 from the chassis and holding the module in the orientation shown in Figure 2-2 and Figure 2-3. 2-2 EMM-E6 Installation Guide ICH1Book Page 3 Tuesday, August 6, 1996 3:06 PM Internal Components Chassis Backplane Connections Dip Switch Bank Channel E BRIM Connector LSI Logic Logic LSI Channel F BRIM Connector EPIM Connector Pins 1926n02 Figure 2-2 EMM-E6 Internal Components Chassis Backplane Connections The EMM-E6 connects to the backplane buses of the MMAC chassis through these multipin connectors. Dip Switch Bank The EMM-E6 provides a bank of eight dual-position, or “dip” switches. Several of these switches are used for testing purposes during the manufacturing process. The dip switches can also be used to clear the NVRAM of the EMM-E6, which contains configuration and local management settings, or to force the EMM-E6 to request a new firmware image from a properly configured BootP server. BRIM Connectors The Channel E and Channel F BRIM connectors allow the EMM-E6 to connect BRIM modules to Ethernet Channels E and F of the EMM-E6. EMM-E6 Installation Guide 2-3 ICH1Book Page 4 Tuesday, August 6, 1996 3:06 PM Chapter 2: Controls and Indicators EPIM Connector Pins The EPIM connector pins are two sets of built-in pins that connect the EMM-E6 Ethernet Channel D to optional EPIM modules. The proper insertion of the EPIM will automatically connect these pins to the connector located on the EPIM. FLASH Memory SIMM Slot (shown populated) BRIM-F Ribbon Connector LSI Logic Logic LSI SDRAM SIMM Slot LDRAM SIMM Slot (shown populated) 1926n03 Figure 2-3 EMM-E6 Internal Components SDRAM SIMM Slot The EMM-E6 motherboard provides the option of upgrading memory capacity by using Single In-line Memory Modules (SIMMs). The EMM-E6 comes with 4 Megabytes (MB) of Shared Dynamic Random Access Memory (SDRAM) built into the module. The SDRAM temporarily stores the packets received be the module while forwarding, filtering, and error checking operations are performed. 2-4 EMM-E6 Installation Guide ICH1Book Page 5 Tuesday, August 6, 1996 3:06 PM Internal Components LDRAM SIMM Slot The EMM-E6 comes with 4 MB of Local Dynamic Random Access Memory (LDRAM) built into the module and one 4 MB SDRAM SIMM, for a total of 8 MB of Shared Dynamic RAM. LDRAM is the “Main” memory from which the switching functionality of the EMM-E6 operates. NOTE Some advanced EMM-E6 operations, such as extended RMON or Cabletron Systems Routing Services, require an EMM-E6 with greater than 8 MB of LDRAM. In these cases, the 4 MB SIMM that is shipped in the LDRAM slot must be upgraded to a higher-capacity SIMM. Contact your Cabletron Systems Sales Representative for more information about available memory upgrades for the EMM-E6. FLASH Memory SIMM Slot The EMM-E6 incorporates 2 MB of FLASH Electrically Erasable Programmable Read Only Memory (FLASH EEPROM). FLASH memory holds the operating instruction code of the EMM-E6. When the module is activated, the instruction code (firmware) held in FLASH memory is forwarded to Main memory, decompressed, and used to start up the EMM-E6. The use of FLASH memory, in conjunction with the runtime download capabilities of the EMM-E6, allows the downloading of firmware to the module without requiring that the module be shut down. The firmware download may be performed at any time during the operation of the module, and the new firmware image will be used at the next reset of the module. BRIM-F Ribbon Connector The BRIM-F ribbon connector provides a connection point for the special ribbon cable used to connect FDDI BRIMs (the BRIM-F6 or BRIM-F0) to Ethernet Channel E of the EMM-E6.

Observe all antistatic precautions when handling sensitive electronic equipment. CAUT ION 1. Remove the shipping material covering the EMM-E6. 2. Verify the contents of the packing carton. The carton, as shipped, should contain the following items: Table 3-1 Contents of EMM-E6 Carton Item Quantity EMM-E6 1 Disks containing firmware images 2 Grounding Strap 1 RJ45 Adapter Kit 1 Release Notes 1 Cabletron Systems Hardware Manuals CD-ROM 1 EMM-E6 Installation Guide 3-1 ICH1Book Page 2 Tuesday, August 6, 1996 3:06 PM Chapter 3: Installation 3. Carefully remove the module from the shipping box. Leave the module inside its non-conductive bag until you are ready to install it. 4. Visually inspect the non-conductive bag. If there are any signs of damage, contact Cabletron Systems Technical Support immediately. 5. Place the static grounding strap properly upon your wrist before opening the non-conductive bag. 6. Open the non-conductive bag by tearing the black and yellow tape seal. ! Do not cut the bag open, as damage to the EMM-E6 may result. CAUT ION 7. Perform a second visual inspection of the module. 3-2 EMM-E6 Installation Guide ICH1Book Page 3 Tuesday, August 6, 1996 3:06 PM Setting Mode Switches 3.2 SETTING MODE SWITCHES A bank of dip switches, located at the top of the EMM-E6 (Figure 3-1), provides several configuration options. All switches ship in the OFF position. Never adjust switch settings while the EMM-E6 is on. Not only is this dangerous, but the change in state (i.e., position) only activates the switch function after restarting or cycling power to the board. ON 1 ALCO GDSO8S 2 3 4 5 6 7 On Off 8 LSI Logic Logic LSI 1926n05 Figure 3-1 EMM-E6 Installation Guide EMM-E6 Dip Switches 3-3 ICH1Book Page 4 Tuesday, August 6, 1996 3:06 PM Chapter 3: Installation Switch definitions are as follows: • Switch 1: Cabletron Systems use only. • Switch 2: Cabletron Systems use only. • Switch 3: Not Used. • Switch 4: Not Used. • Switch 5: Cabletron Systems use only. • Switch 6: Forced Download. Changing the state of this switch (i.e., moving the switch from one position to another) forces a BootP download. After changing the position of Switch 6 and restarting the EMM-E6, the EMM-E6 requests a new image download until it either receives a new image or the reset button on the front panel is pressed. When the reset button is pressed, the EMM-E6 continues trying to contact a BootP server, but will timeout in approximately one minute. If the EMM-E6 times out, the image is loaded from its FLASH memory. NOTE Do NOT change the state of Switch 6 unless you have a station acting as a BootP server for the EMM-E6. This BootP station must reference a station that is acting as a TFTP (Trivial File Transfer Protocol) server and that contains the EMM-E6 image file. The EMM-E6 will request the location of the image file from the BootP server and use TFTP to download that file from the TFTP server. If one of these requirements is not met, the EMM-E6 Forced Download operation will not be completed correctly. • 3-4 Switch 7: NVRAM Reset. The EMM-E6 uses NVRAM to store user-entered parameters such as IP addresses, device name, etc. Changing the state of this switch (i.e., moving the switch from one position to another) resets these parameters to the factory defaults. EMM-E6 Installation Guide ICH1Book Page 5 Tuesday, August 6, 1996 3:06 PM Pre-Installation Test Once the EMM-E6 resets, you can either use the defaults or re-enter your own parameters. The EMM-E6 stores these parameters in NVRAM when the device powers down. These parameters remain in NVRAM until the state of the switch changes again. NOTE • Switch 8: Password Defaults. Changing the state of this switch (i.e., moving the switch from one position to another and leaving it there) clears user-entered passwords stored in NVRAM, and restores default passwords. Once reset you can use the defaults or re-enter your passwords. NOTE 3.3 Do not change the state of Switch 7 unless you intend to reset the EMM-E6 user parameters to the factory default settings. Do not change the state of Switch 8 unless you want to reset the EMM-E6 user-configured passwords to their factory default settings. PRE-INSTALLATION TEST Before installing the EMM-E6 in a live network, you may want to test the module in a controlled situation to ensure that it is bridging traffic. You can perform this test with two workstations (see Figure 3-2), using an MMAC with an EMM-E6 and Ethernet Media Interface Module (MIM, RMIM, or XMIM) installed and set up as follows: 1. Install the EMM-E6 into an MMAC that is not attached to a network. 2. Install an Ethernet Media Interface Module (MIM), Repeating Media Interface Module (RMIM), or Port Assignment Media Interface Module (XMIM) in the MMAC. Follow the installation instructions found in the Installation or User’s Guide shipped with that product.

However, when you install your device, keep the following in mind: Any installation operations should be performed only by qualified personnel. ! CAUT ION ! You may only install the EMM-E6 in slots 1 and 2 (farthest slots to the right) of the MMAC chassis. The EMM-E6 uses both slots. Observe all antistatic precautions when handling sensitive electronic equipment. CAUT ION Install the EMM-E6 into the MMAC-FNB (backplane) as follows: NOTE We recommend powering down your MMAC when inserting or removing modules, even though Cabletron Systems modules have “hot swap” capabilities. 1. Remove the safety bars that protect the chassis and remove any module to be replaced or blank MMAC slot covers, in accordance with the installation and removal procedures for these items. 2. Holding the EMM-E6 by the front panel, or by the edges of the board, align the bottom and top edges of the printed circuit board with the guides. Make sure that both the bottom and top edges of the printer circuit board rest in these guides. 3. Slide the EMM-E6 (Figure 3-3) into slots 1 and 2 of the MMAC chassis. ! Forcing a misaligned module into place can damage the EMM-E6 or the MMAC backplane. CAUT ION EMM-E6 Installation Guide 3-7 ICH1Book Page 8 Tuesday, August 6, 1996 3:06 PM Chapter 3: Installation 4. Firmly press the module connections into the backplane. Do not try to force the module into place or use the knurled knobs to draw the module into the backplane. 1926n07 Module Guide Channels Figure 3-3 Installing the EMM-E6 5. Secure the module to the MMAC chassis by tightening the knurled knobs. If you do not tighten the knurled knobs, vibration can cause the module to lose contact with the backplane and disrupt your network. 6. Reinstall the MMAC chassis safety bars. 7. Power-up the MMAC (if it is not already ON). 8. Observe the status of the LANVIEW LEDs (Figure 3-4) on the EMM-E6. When the CPU LED is amber, the module is in boot state.

Proceed to Section 3.5, Connecting to the Network, to connect the appropriate network segments to the EMM-E6 and individual EPIMs (for connections to individual BRIMs, refer to the appropriate BRIM Guides). EMM-E6 Installation Guide 3-9 ICH1Book Page 10 Tuesday, August 6, 1996 3:06 PM Chapter 3: Installation 3.5 CONNECTING TO THE NETWORK This section gives procedures for connecting the EMM-E6 and various EPIMs to the network. Refer to the list below and follow the procedures in the subsection for appropriate module type: • Connecting a 10BASE-T Segment to an EPIM-T: Section 3.5.1 • Connecting a 10BASE-F Segment to an EPIM-F2 or EPIM-F3: Section 3.5.2 • Connecting a 10BASE-F Segment to an EPIM-F1: Section 3.5.3 • Connecting an AUI Segment to an EPIM-X or EPIM-A: Section 3.5.4 • Connecting a 10BASE2 Segment to an EPIM-C: Section 3.5.5 3.5.1 NOTE Connecting a 10BASE-T Segment to an EPIM-T For proper operation, the EPIM-T module to be configured for use in the EMM-E6 module must be of EPIM board revision 04 or greater. Board revision numbers are found following the part number printed on the Printed Circuit Board of the EPIM. Before connecting a segment to the EPIM-T, check each end of the segment to determine wire crossover. If the wires do not cross over, use the switch on the EPIM-T to internally cross over the RJ45 port. Refer to Figure 3-5 to properly set the EPIM-T crossover switch. NOTE 3-10 To establish a link, you must have an odd number of crossovers (preferably one) between 10BASE-T devices of the same type (i.e., from repeater to repeater or transceiver to transceiver).

The connector will only insert and lock if the raised locking clip of the RJ45 connector is inserted into the correct location. 2. Press the RJ45 connector into the port until the click of the locking clip is felt. The pressure required to perform this should be minimal. If you encounter resistance or excessive friction, remove the connector and check the port for obstruction. Also, verify that the connector and the port are of the same type. Once the locking clip snaps into place, the RJ45 connector will remain in the port. 3. Check that the LNK indicator LED is ON. If the indicator is not ON, the port does not have a valid link. Perform each of the following steps until you reach a resolution of the problem and achieve a link. a. Check that the 10BASE-T device at the other end of the twisted pair segment is ON. b. Verify that the RJ45 connectors on the twisted pair segment have the proper pinouts.

Check the cable for continuity. d. Check that the twisted pair connection meets dB loss and cable specifications outlined in Appendix C, Ethernet Cabling Requirements. 4. If you still cannot establish a link, contact Cabletron Systems Technical Support. To remove the RJ45 connector from the port once it is locked in, grasp the cable where it enters the network device. Using your finger or a non-conductive probe (the cap of a ballpoint pen is a useful tool for recessed ports) pinch the exposed arm of the locking clip towards the main body of the housing. When the arm contacts the housing, the locking clip has been disengaged. Without releasing the arm, gently pull the RJ45 connector directly out of the port. If the connector will not come out, there may be damage to the locking clip. Examine the arm of the locking clip. While pressing the arm back toward the shell of the connector, verify that the clip, located within the port, is being moved. If the clip is broken, you may need to use a non-conductive probe to disengage the locking clip. Do not place foreign objects into device ports while they are connected to a power source. 3-12 EMM-E6 Installation Guide ICH1Book Page 13 Tuesday, August 6, 1996 3:06 PM Connecting to the Network 3.5.2 NOTE Connecting a 10BASE-F Segment to an EPIM-F2 or EPIM-F3 For proper operation, the EPIM-F2 module to be configured for use in the EMM-E6 module must be of EPIM board revision 05 or greater. EPIM-F3 modules used in the EMM-E6 must be of EPIM board revision 02 or greater. Board revision numbers are found following the part number printed on the Printed Circuit Board of the EPIM. Each fiber optic link consists of two strands of fiber optic cabling: the transmit (TX) and the receive (RX). The transmit strand from a module port connects to the receive port of a fiber optic Ethernet device at the other end of the segment. The receive strand of the applicable port on the module connects to the transmit port of the fiber optic Ethernet device. Cabletron Systems recommends labeling fiber optic cables to indicate receive and transmit ends. Many cables are prelabeled, providing matching labels or tapes at both ends of each strand of cable. ! CAUT ION Do not touch the ends of the fiber optic strands, and do not let the ends come in contact with dust, dirt, or other contaminants. Contamination of cable ends causes problems in data transmissions. If necessary, clean contaminated cable ends using alcohol and a soft, clean, lint-free cloth. 1. Remove the protective plastic covers from the fiber optic ports on the applicable port on the module, and from the ends of the connectors on each fiber strand. 2. Attach one fiber to the applicable receive port on the module. Insert the ST connector into the port with the alignment slot on the connector inserted over the locking key on the port. Turn the connector clockwise to lock it down. EMM-E6 Installation Guide 3-13 ICH1Book Page 14 Tuesday, August 6, 1996 3:06 PM Chapter 3: Installation 1926n10 Figure 3-7 ST Connector Insertion 3. Attach the other fiber of the pair to the applicable transmit port on the module. Use the same procedure for insertion of the ST connector. 4. At the other end of the fiber optic cable, attach the fiber pair to the transmit and receive ports of the device. If link indicators are present for the fiber optic connection, check that they are ON. If an indicator is present but not ON, that port does not have a valid link. Perform each of the following steps until you reach a resolution of the problem and achieve a link. • Check that the device at the other end of the link is ON. • Verify proper crossover of the fiber strands. Try swapping the transmit and receive connections at only one end of the link. • Verify that the fiber connection meets the dB loss specifications outlined in Appendix C, Ethernet Cabling Requirements. If you are still unable to establish a link, attempt to make the connection between the devices with another fiber optic cable. If this is unsuccessful, contact Cabletron Systems Technical Support. 3-14 EMM-E6 Installation Guide ICH1Book Page 15 Tuesday, August 6, 1996 3:06 PM Connecting to the Network 3.5.3 NOTE !

Board revision numbers are found following the part number printed on the Printed Circuit Board of the EPIM. To connect a thin coaxial cable segment to an EPIM-C perform the following steps: Before attaching a male BNC connector to a female BNC barrel connector or terminator, look into the end of the connector to verify that the gold contact pin is present and centered. Any bent or broken pins may not connect properly and should be replaced. 1. Set the Internal Termination (TERM) switch, located to the right of the port and labeled TERM, to one of the following positions: a. The ON position ( ) to internally terminate the thin coaxial cable segment at the port. Thin coaxial cable segments may be directly connected to the port. b. The OFF position ( ) to not internally terminate the thin coaxial cable segment at the port. Segments may only be connected through T-connectors which are connected to properly terminated segments on both ends. 3-18 EMM-E6 Installation Guide ICH1Book Page 19 Tuesday, August 6, 1996 3:06 PM Connecting to the Network NOTE Failure to terminate each T-connector segment may result in improper segment operation. Place a terminator on any open female connection on the T-connector. 2. Align the guide channels of the BNC (male) metal housing with the locking keys of the BNC barrel (female) connector on the EPIM. Slide the metal housing of the male connector straight over the metal housing of the female connector. 3. Once the housing stops moving in, turn the metal housing clockwise while continuing to apply light forward pressure. 1926n13 Figure 3-10 BNC Connector Insertion 4. The locking keys of the female connector will pull the connector in until they reach the circular locking holes at the end of the guide channels. The keys will click the connector into place and hold it there. To remove the BNC connector, perform the steps above in reverse order, turning the metal housing counter-clockwise and pulling the connector straight off of the female BNC connector.

Before attempting to install the EMM-E6 or any additional EPIMs or BRIMs, review the requirements and specifications outlined in this chapter. NOTE C.1 Your network installation must meet the conditions, guidelines, specifications, and requirements included in this chapter to ensure satisfactory performance of this equipment. Failure to follow these guidelines may result in poor network performance. NETWORK REQUIREMENTS Take care in planning and preparing the cabling and connections for your network. The quality of the connections, the length of cables, and other conditions of the installation play critical roles in determining the reliability of your network. Refer to the sections which follow that apply to your specific network configuration. C.1.1 10BASE-T Twisted Pair Network When connecting a 10BASE-T segment to an EMM-E6 (using an EPIM-T), ensure the network meets the following requirements: • Length: The IEEE 802.3 10BASE-T standard requires that 10BASE-T devices transmit over a 100 meter (328 foot) link using 22-24 AWG unshielded twisted pair wire. However, cable quality largely determines maximum link length. If you use high quality, low attenuation cable, you can achieve link lengths of up to 200 meters. Cable delay limits the maximum link length to 200 meters. NOTE Losses introduced by connections at punch-down blocks and other equipment reduce total segment length. For each connector or patch panel in the link, subtract 12 meters from the total length of your cable. EMM-E6 Installation Guide C-1 ICH1Book Page 2 Tuesday, August 6, 1996 3:06 PM Appendix C: Ethernet Cabling Requirements • Insertion Loss: Between frequencies of 5.0 and 10.0 MHz, the maximum insertion loss must not exceed 11.5 dB. This includes the attenuation of the cables, connectors, patch panels, and reflection losses due to impedance mismatches in the link segment. • Impedance: Cabletron Systems 10BASE-T products work on twisted pair cable with 75 to 165 ohms impedance. Unshielded Twisted Pair cables typically have an impedance of between 85 and 110 ohms. You can also use Shielded Twisted Pair cables, such as IBM Type 1 cable, but keep in mind that this cable has an impedance of 150 ohms. The high impedance of the IBM Type 1 cable increases signal reflection. However, due to cable shielding and the subsequent lack of crosstalk between shielded pairs, signal reflection has little effect on the quality of the received signal. • Jitter: Intersymbol interference and reflections can cause jitter in the bit cell timing, resulting in data errors. 10BASE-T links must not generate more than 5.0 ns of jitter. Make sure your cable meets 10BASE-T link impedance requirements to rule out jitter as a concern. • Delay: The maximum propagation delay of a 10BASE-T link segment must not exceed 1000 ns. This 1000 ns maximum delay limits the maximum link segment length to no greater than 200 meters. • Crosstalk: Signal coupling between different cable pairs within a multi-pair cable bundle causes crosstalk. 10BASE-T transceiver design alleviates concerns about crosstalk, provided the cable meets all other requirements. • Noise: Crosstalk, or externally induced impulses, can cause noise. Impulse noise may cause data errors if the impulses occur at very specific times during data transmission. Generally, noise is not a concern. If you suspect noise-related data errors, you may need to reroute the cable or eliminate the source of the impulse noise. C-2 EMM-E6 Installation Guide ICH1Book Page 3 Tuesday, August 6, 1996 3:06 PM Network Requirements • Temperature: Multi-pair PVC 24 AWG telephone cables typically have an attenuation of approximately 8-10 dB/100 m at 20°C (68°F). The attenuation of PVC insulated cable varies significantly with temperature. At temperatures greater than 40°C (104°F), we strongly recommend using plenum-rated cable to ensure attenuation remains within specification. C.1.2 Multimode Fiber Optic Network When connecting a multimode fiber optic link segment to the EMM-E6 (using an EPIM-F1/F2), ensure the network meets the following requirements: • Cable Type: Use the following multimode fiber optic media: - • Attenuation: You must test the fiber optic cable with a fiber optic attenuation test set adjusted for an 850 nm wavelength. This test verifies that the signal loss in a cable falls within the following acceptable levels: - • 50/125 µm fiber optic cabling 62.5/125 µm fiber optic cabling 100/140 µm fiber optic cabling 13.0 dB or less for a 50/125 µm fiber cable segment 16.0 dB or less for a 62.5/125 µm fiber cable segment 19.0 dB or less for a 100/140 µm fiber cable segment Budget and Propagation Delay: When you determine the maximum fiber optic cable length to incorporate fiber runs into your network, you must calculate and consider the fiber optic budget (a total loss of 10.0 dB or less is permissible between stations) and total network propagation delay. To determine the fiber optic budget, combine the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors. Typical loss for a splice and connector (together) equals 1 dB or less. EMM-E6 Installation Guide C-3 ICH1Book Page 4 Tuesday, August 6, 1996 3:06 PM Appendix C: Ethernet Cabling Requirements Network propagation delay is the amount of time it takes a packet to travel from the sending device to the receiving device. Total propagation delay allowed for the entire network must not exceed 25.6 µs in one direction (51.2 µs round trip). If the total propagation delay between any two nodes on the network exceeds 25.6 µs, you must use bridges or switches. • Length: The maximum possible multimode fiber optic cable length is 2 Km (1.24 miles). However, IEEE 802.3 FOIRL specifications specify a maximum of 1 Km (0.62 miles). C.1.3 Single Mode Fiber Optic Network When connecting a single mode fiber optic link segment to a hub (using an EPIM-F3), ensure the network meets the following requirements: • Cable Type: Fiber optic link segments should consist of 8/125 or 12/125 µm single mode fiber optic cabling. You can also use 62.5/125 µm multimode cable with the EPIM-F3; however, multimode cable allows for greater optical loss, and limits the possible distance to 2 Km. • Attenuation: You must test the fiber optic cable with a fiber optic attenuation test set adjusted for a 1300 nm wavelength. This test verifies that the signal loss in a cable falls within the acceptable level of 10.0 dB or less for any given single mode fiber optic link. • Budget and Propagation Delay: When you determine a maximum fiber optic cable length, you must calculate and consider the fiber optic budget (a total loss of 10.0 dB or less between stations) and total network propagation delay. To determine the fiber optic budget, combine the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors. Typical loss for a splice and connector (together) equals 1 dB or less. Network propagation delay is the amount of time it takes a packet to travel from the sending device to the receiving device. Total propagation delay for the entire network must not exceed 25.6 µs in one direction (51.2 µs round trip). If the total propagation delay exceeds 25.6 µs, you must use bridges or switches to re-time the signal. C-4 EMM-E6 Installation Guide ICH1Book Page 5 Tuesday, August 6, 1996 3:06 PM Network Requirements • Length: If you meet all system budgets, the maximum single mode fiber optic cable length can reach 5 Km (3.1 miles) with bridges or switches at each segment end. FOIRL specifications specify a maximum of 1 Km (0.62 miles). C.1.4 10BASE2 Coaxial Cable Network When connecting a thin coaxial cable segment to your hub (using an EPIM-C), ensure your network meets the following requirements: • Cable Type: Use only 50 ohm RG-58 A/U type coaxial cable for thin coaxial cable segments. • Length: The thin coaxial cable segment must not exceed 185 meters. • Terminators: Terminate each end of a thin coaxial cable segment. • Connectors: You can use up to 29 T-connectors throughout the length of the cable segment for host connections. Ensure that all connections are spaced 0.5 meters or more from one another or from terminators. If you use an excessive number of barrel connectors within the cable segment (e.g., finished wall plates with BNC feed-throughs), you may need to reduce the number of host connections. For special network design information, contact Cabletron Systems Technical Support. • Grounding: For safety, ground only one end of a thin coaxial cable segment. Do NOT connect EPIM BNC ports to earth ground. Connecting a thin coaxial cable segment to earth ground at more than one point could produce dangerous ground currents. C.1.5 Transceiver Requirements When you connect an external network segment to an EPIM-A in your hub through a transceiver, that transceiver must meet IEEE 802.3 standards or Ethernet version 1.0 or 2.0 requirements. The transceiver must also have SQE disabled.
