TRMM-2 Quick Installation Guide Select one of the four installation scenarios and proceed as directed. Side View of TRMM-2 and Detail of Ring Speed Switches Scenario I: Full Backplane - One Managed Ring Number of Networks: ONE Installation: new MMAC hub STN Interface: not used MIM Types: single-ring (TRMIM, TRRMIM) 1. Set switch #1 for speed of FNB ring 1 interface (4 or 16 Mbps). 2. Insert TRMM-2 into Slot 1 and tighten knurled knobs . 3. Set ring speed jumper on each new MIM to match switch #1. 4. Install MIMs and tighten knurled knobs . 5. Access the Local Management System Level screen and assign an IP address to the TRMM-2. Save the changes. TRMM-2 then resets itself and installation is complete.

Using switches #1, 2, 3, 7, and 8, set ring speeds (4 or 16 Mbps) for each FNB ring and for the STATION interface. 2. Insert TRMM-2 into Slot 1 and tighten knurled knobs . 3. Install all TRXMIMs and TDRMIMs and tighten knurled knobs . 4. Access Local Management Chassis Status View screen, switch the screen to Port Assignment mode, and make desired port-assignments to FNB rings. Switch at least one lobe port onto FNB ring 2, 3, or 4 for the STATION interface. 5. Attach the STATION interface cable to a port-assigned lobe port. Refer to the STATION Assignment Rules below. 6. Access the Local Management System Level screen and complete the STN assignment field to indicate the location of the STATION interface connection. 7. Access the Local Management System Level screen and assign an IP address to the TRMM-2. Save the changes. TRMM-2 then resets itself and installation is complete. STATION Assignment Rules: The STATION port interface must be inserted only into a lobe port on a ring that is isolated from the TRMM-2’s FNB ring 1 interface. If using a port-assigned lobe port, that lobe port must be assigned to a ring other than FNB ring 1. If using a lobe port on a single-ring MIM, the backplane must be split somewhere between the MIM and the TRMM-2. If using a lobe port in a different hub, the destination ring must not be joined by ring in / ring out connection with FNB ring 1.
