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.
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.

Observe all antistatic precautions when handling sensitive electronic equipment.
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.
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.
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.
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.

ICH1Book Page 7 Tuesday, August 6, 1996 3:06 PM Installation 3.4 INSTALLATION Installing the EMM-E6 into any MMAC hub is an easy operation and requires no special tools. 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.
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.

ICH1Book Page 1 Tuesday, August 6, 1996 3:06 PM APPENDIX C ETHERNET CABLING REQUIREMENTS This chapter contains general networking guidelines. 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.
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.
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.
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.
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.
