Page 7: Chapter 1 Introduction
INTRODUCTION CHAPTER 1 INTRODUCTION The FDCMIM-04/08/24/28/34/38/44/48 are components of a modular dual attached concentrator. These components attach to an FDDI dual ring through the Cabletron Systems FDMMIM, FDMMIM-04, FDMMIM-24, or FDMMIM-30. Note: Throughout this manual, unless otherwise noted, the term FDCMIM refers to the FDCMIM-04/08/24/28/34/38/44/48. -

INTRODUCTION FDCMIM-04 FDCMIM-24 FDDI Figure 1-1. FDCMIM-04 / 24 / 34 / 44 FDDI Concentrator 1.2 OVERVIEW The FDCMIM is a concentrator module that resides in an MMAC network hub containing a Flexible Network Bus (FNB). The FDCMIM acts as a modular component in a Dual Attached Concentrator. - Page 9 FDCMIM-08 FDDI Figure 1-2. FDCMIM-08 / 28 / 38 / 48 FDDI Concentrator By using an FDMMIM, FDMMIM-04, FDMMIM-24, or FDMMIM-30 you can manage adjacent FDCMIMs through FDMMIM Local Management, the out-of-band management facility resident on the FDMMIM and FDMMIM-04 modules. You can also manage FDCMIMs with Cabletron Systems SNMP management tools such as ®...

Page 11: Chapter 2 Configuration And Installation
CONFIGURATION AND INSTALLATION This chapter lists MMAC configuration guidelines, explains how to configure the FDCMIM in a hub that also holds Ethernet or Token Ring MIMs, and then explains how to install the FDCMIM as a stand- alone concentrator in an FDDI hub. 2.1 INSTALLATION REQUIREMENTS Before you start the installation, decide how you want to configure the MMAC. - Page 12 CONFIGURATION AND INSTALLATION To better explain how to configure your MMAC, refer to the following examples. Figure 2-1 illustrates how the combined load of two FDCMIMs exceeds the available power of an MMAC-3FNB. 11.8 amps FDCMIM-08 Figure 2-1. FDCMIMs in an MMAC-3FNB Figure 2-2 represents an MMAC-5FNB equipped with dual power supplies and three FDCMIMs.

FDCMIMs in an MMAC-M8FNB When unsure of a hub’s ability to support a planned MIM configuration, check the appropriate manuals to determine the amount of power consumed by each MIM (amps at 5 Vdc), and then check your MMAC power supply configuration (single or multiple power supplies) to determine if you have sufficient power available to support the configuration. -
Page 14: Fdcmims Exclusively
CONFIGURATION AND INSTALLATION 2.3.1 FDCMIMs Exclusively By mixing FDCMIMs, you can create a stand-alone FDDI network of 4 to 56 nodes (7 FDCMIM-X8s in an MMAC-M8FNB = 56 master ports). Depending on MMAC shunting capabilities, you may have to install your FDCMIMs in adjacent slots to ensure continuity. -

CONFIGURATION AND INSTALLATION 2.3.2 IRM3 and Ethernet MIMs with FDCMIMs This example uses the IRM3, but the same guidelines apply if you are using an IRM, IRM2, or IRBM. In Figure 2-4, the MMAC-5FNB has an IRM3 in slot 1, TPMIM-22s in slots 2 and 3, and FDCMIMs in slots 4 and 5. - Page 16 CONFIGURATION AND INSTALLATION POWER FAIL MMAC - 5PSM Figure 2-4.

Page 17: Trmm And Token Ring Mims With Fdcmims
Even though RMIMs can place Ethernet traffic on the bus that normally handles FDDI traffic, FDDI MIMs can still reside in the same hub with RMIMs. RMIMs determine whether or not the MIM that resides in the next higher numbered MMAC slot is an Ethernet MIM. -

Medium Dependent (PMD) ports. Note: When connecting two twisted pair ports together (e.g., an M type port on an FDCMIM-24 to an F7069 Desktop Network Interface (DNI) card), a transmit and receive cross-over must occur between the two devices (i.e., within the cable). -
Page 19: Installing The Fdcmim
2.5 INSTALLING THE FDCMIM The FDCMIM has “hot swap” capabilities. This means you can insert and remove the module without first turning off the MMAC. Occasionally, depending on the MMAC configuration, other MIMs in the hub may go into a reset condition when you hot swap an FDCMIM. A reset condition can cause a momentary, but self correcting, interruption in network service. - Page 20 CONFIGURATION AND INSTALLATION 6. Once the module seats in the backplane, tighten the two knurled knobs. This step is important. If you do not tighten the knurled knobs, vibration can cause the module to lose contact with the backplane and disrupt your network. 7.

Page 21: Chapter 3 Using Lanview
LANVIEW is a visual diagnostic and status monitoring system developed by Cabletron Systems. LANVIEW LEDs can help you troubleshoot network problems such as open segments or FDCMIM power problems. The following sections describe FDCMIM LEDs. 3.1 FDCMIM STATUS LEDS The FDCMIM has two LEDs, PWR and FNB, that show MIM status. PWR (Power) When ON, this green LED indicates that the FDCMIM is getting power from the MMAC. -

PST (Port Status) This multi-state LED can indicate the following: Green Amber Note: You must use an FDMMIM in conjunction with the FDCMIM to... - Page 23 USING LANVIEW LNK (Media Link OK) When ON, this green LED indicates that a connection exists between the FDCMIM and the node at the other end of the port cable segment. To ensure you maintain the link, the port generates an idle signal when not transmitting data.
