Page 12: Chapter 2 Installation Requirements/ Specifications
REQUIREMENTS/SPECIFICATIONS Before you attempt to install your concentrator module, review the installation requirements and operating specifications that are outlined in this chapter. Your network installation must meet the conditions, guidelines, specifications, and requirements included in this chapter to obtain satisfactory performance from this equipment. Failure to follow these guidelines could produce poor network performance. -
Page 13: Operating Specifications
REQUIREMENTS/SPECIFICATIONS • Attenuation - The fiber optic cable must be tested with a fiber optic attenuation test set that is adjusted for an 850 nm wavelength. This test verifies that the signal loss in a cable is within an acceptable level: 13.0 dB or less for 50/125 fiber cable segment. -
Page 14: Ring Order
Ring boards via the FNB, the ring order is in MMAC slot number order, and then port number order within each Token Ring board. Example: TRFMIM-22 in slot 1 with ports 2, 5, 8, & 12 in use.

Page 17: Chapter 3 Installing The Concentrator Module
CONCENTRATOR MODULE This chapter contains instructions for installing your concentrator module into a Cabletron Systems MMAC product and connecting token ring stations at the concentrator module’s trunk coupling unit (TCU) ports. Check that all requirements listed in Chapter 2, Installation Requirements/ Specifications, have been met before installing and operating the concentrator module. -
Page 18: Unpacking The Concentrator Module
INSTALLING THE CONCENTRATOR MODULE NOTE: The FNB is a full-height, full-width backplane that links Cabletron Systems Token Ring products. MMAC-3s and MMAC-8s (without an FNB) can be upgraded with an FNB, providing greater flexibility in configuring your system. Contact Cabletron Systems Technical Support for more information. -
Page 19: Configuring The Concentrator Module
3.2 CONFIGURING THE CONCENTRATOR MODULE Position the hardware jumper on the proper pins on the concentrator module to select either 4 or 16 Mbit/s as the default network ring speed (see Figure 3-1). The speed setting is a factor in determining the maximum lobe length. -
