Product Description AT-MR902 100Base-FX Module Figure 5 shows the back panel of an AT-MR912TX with an AT-MR902 100Base-FX Module installed. Figure 5: AT-MR902 100Base-FX Module As previously stated, you have the option of using either Straight Tip (ST) or Subscriber Channel (SC) fiber optic Ethernet-to-Ethernet connectors.
PAGE 29
AT-MR912TX Hub Installation Manual Figure 6 shows a generic illustration of both types of connectors. Figure 6: ST and SC Connectors Straight Tip Connectors Straight Tip connectors mate through a two-pin, bayonet-style interface. They are popular simply because they have less attenuation and less vulnerability to human error than previous fiber optic connectors such as a Sub Miniature Assembly (SMA).
PAGE 30
Product Description Figure 7 shows an ST connector. Figure 7: ST Connector This connector uses a spring loaded twist and lock coupling similar to conventional BNC connectors that are used with coaxial cabling. Note that, since the ST connector is keyed, you should gently rotate the connector to ensure proper mating of the ST plug receptacle. Be careful not to force the connector mating or you might damage the hub’s connector.

Product Description 100Base-FX Wiring Specifications An earlier IEEE FOIRL standard limited a fiber optic segment length to 1 km (1,000 meters or 3,280 feet). That is, the fiber optic cable that connected two repeaters was limited to 1 km (3,280 ft.). While the more recent IEEE 802.3 100Base-FX standard is compatible with FOIRL, it can travel up to 2 km. (2,000 meters or 6,560 feet) using multimode duplex fiber optic cable in a point-to-point link which directly attaches two devices.
PAGE 33
Chapter 2 Installation Power AT-MR912TX hubs have an internal universal power supply rated at 100-120/ 200-240 VAC, 50/60 Hz. As noted in Chapter 1, ATI provides different power cords based on the requirements of different countries. Figure 10 shows the location of both the power receptacle and both ventilation outlets. Ventilation Outlets Power Receptacle Figure 10: Power Receptacle Maximum power consumption for the standalone AT-MR912TX-10A, ATMR912TX-20A or AT-MR912TX-30A is 32W.
PAGE 34
Installation Ventilation All AT-MR912TX hubs have an internal fan and openings on both sides for ventilation. Note Make sure the ventilation openings on the unit are not blocked. Maximum ambient operating temperature is 122° F (50° C). Maximum ambient storage temperature is from 14° F to 158° F (-10° C to 70° C). Network Specifications Table 6 provides an overview of IEEE 802.3 and 802.3u specifications for 10Base-T and 100Base-TX network configurations using twisted-pair wire. Table 6:IEEE 802.3 and 802.
PAGE 35
AT-MR912TX Installation Manual For the foregoing reasons, it is absolutely vital that all cabling used with 100Base-TX connections is Category 5. Using any other category, or a poor quality cable, for a 100Base-TX connection will potentially have high error rates or will not transfer data at all. The six common modular cable specifications and their applicability to 100Base-TX networks are shown in Table 7.
PAGE 36
Installation Alternative Installations AT-MR912TX hubs can be installed within four different configurations: standalone, cascaded, stacked and cascaded/stacked. The following hub models can be used for standalone or cascaded hub configurations. They do not have ATI’s optional AT-MR901 Stacking Module installed: ❑ AT-MR912TX-10A ❑ AT-MR912TX-20A ❑ AT-MR912TX-30A The following models incorporate ATI’s AT-MR901 Stacking Module as a standard feature.
PAGE 37
AT-MR912TX Installation Manual Installation procedures are as follows: 1. Ensure that the package includes the required items presented in Chapter 1. 2. Remove all equipment from the packing box and store the box and packing materials in a safe place. Your hub may need to be transferred in the future. 3. Insert the female end of the power cord into the Power Receptacle on the back of the unit. 4. Insert the male end of the power cord into an electrical output of the appropriate power. 5.
PAGE 38
Installation Rack mounting Rack mounting will require use of the rackmount installation kit which is provided. The 19-inch rackmount kit, standard with all models, consists of two brackets and eight panhead screws. The installation of these brackets is shown below. Note that, for clarification, the illustration shows the back side of the hub. Figure 13: Rackmount Brackets For additional information about rackmount installation kits, please contact your ATI sales representative.
PAGE 39
AT-MR912TX Installation Manual Cascaded Installation You do not need to upgrade a standalone AT-MR912TX hub to enable cascading. From the illustration below, connection is established between the MDI Port 12 on one hub (the bottom hub in this example) and any port (1 through 12) on a second AT-MR912TX hub (Port 11 on the upper hub in the example). Figure 14: Cascaded Hubs 1. Make sure the package includes all of the required parts 2.
PAGE 40
Installation 7. Check the front panels to make sure the green power (PWR) LEDs are illuminated. 8. As Figure 13 on page 18 illustrates, Port 12 (MDI) of the bottom hub is connected to Port 11 on the upper hub in the cascaded sequence. 9. Plug all Category 5 STP/UTP cables into the 100Base-TX network ports (RJ-45 connectors) on the front of the units. 10. Plug the opposite end of each 100Base-TX cable into a network node or workstation as appropriate.
PAGE 41
AT-MR912TX Installation Manual Stacked Installation AT-MR912TX-19A, AT-MR912TX-29A and AT-MR912TX-39A models are designed to interoperate with similar models in a stacked hub configuration using ATI’s AT-MR901 Stacking Module. In a stacked configuration, all hubs in the stack logically appear to your network as a single hub. This configuration will, subsequently, support up to 72 network nodes. You cannot connect a standalone AT-MR912TX hub in a stacked configuration unless it has first been upgraded.
PAGE 42
Installation 3. Slide the AT-MR901 Stacking Module into the back panel port opening, as shown in Figure 15. Ensure that the module is seated in the internal connector and the module faceplate is flush with the surface of the back panel. Figure 15: Installing an AT-MR901 Stacking Module 4. Secure the stacking module in place with the four screws you removed in Step 2 above.
PAGE 43
AT-MR912TX Installation Manual 2. Install the brackets as indicated in the following figure. Figure 16: Installing Stacking Brackets 3. Attach the power cords of all units. 4. Use the SCSI Type II cable to connect the OUT port on the bottom unit with the IN port on the upper unit. Continue this process until you have connected the final hub. 5. Do not match OUT to OUT or IN to IN when connecting the stackable ports of any pair of hubs. 6.
PAGE 44
Installation You are now ready to operate your 100Base-TX network in a stacked hub configuration as shown in Figure 17 (note that — for clarification purposes only — this illustration shows four hubs without stacking brackets. As previously noted, you can stack up to six hubs) SCSI II stacking cables AT-MR901 Stacking Modules Figure 17: Stacked Configuration Stacked/Cascaded Installation First, recall that the basic 802.
PAGE 45
AT-MR912TX Installation Manual Note Once you connect AT-MR912TX hubs in a stacked configuration, they effectively become Class I repeaters. That is, while you can cascade two stacked hub configurations, you must pay careful attention to Ethernet repeater timing rules which limit the way repeaters may be connected. Foremost among these rules is the collision domain timing constraint which addresses the propagation delay of a network.
PAGE 46
PAGE 47
Chapter 3 Troubleshooting Connectivity Testing Follow the steps outlined below to test for a valid connection as well as confirm the correct operation of the network. 1. Connect port 1 and port 2 of a single AT-MR912TX to two nodes or workstations and turn on the hub power supply by connecting the AC power cord. 2. Check to make sure the Link/Activity LEDs of both port 1 and port 2 are illuminated. 3.
PAGE 48
Troubleshooting Power Check Check the power (PWR) LED on the front of the AT-MR912TX. This green LED should be illuminated. If the power LED is not on, check both ends of the AC power cord. Make sure the power cord is plugged into a functioning wall outlet and that it is properly inserted into the AT-MR912TX power receptacle on the back of the unit. Note There is no “power” switch on the AT-MR912TX per se. If the power cord is properly connected, the hub should be receiving power.
PAGE 49
AT-MR912TX Installation Manual Is the AT-MR902 100Base-FX Module LED illuminated? The AT-MR902 100Base-FX Module (FX/ON) LED on the front of the AT-MR912TX will illuminate when a proper connection between the corresponding 100Base-FX port and the equipment connected to it is established. If this LED is not illuminated, check for the problems listed below and make corrections as necessary. Problem 1: The cable has been cut, damaged, or is the wrong type of cable.
