Locate the power cord retaining clip, as shown in Figure 8. Figure 8. Power Cord Retaining Clip 2. Install the clip on the AC power connector on the back panel of the switch.
Chapter 2: Installation Installing the Switch on a Desktop or Table You may install the switches on a desktop or table, or in a standard 19inch equipment rack. To install the switch in a rack, see “Installing the Switch in an Equipment Rack” on page 41. To place the switch on a desktop or table, perform the following procedure: 1. Remove all equipment from the package and store the packaging material in a safe place. 2.
AT-GS908M, AT-GS916M, and AT-GS924M Switches Installation Guide Installing the Switch in an Equipment Rack Note The AT-GS916M and AT-GS924M rack mounting hardware is included in the shipping package. However, the AT-GS908M rack mounting equipment must be purchased separately. The rack mounting kit model number is AT-RKMT-J05. To install the switch in a standard 19-inch equipment rack, perform the following procedure: 1.
Chapter 2: Installation 3. Mount the switch in a standard 19-inch equipment rack using four equipment rack screws (not provided with the switch). See Figure 11. Figure 11. Mounting the Switch in an Equipment Rack 4. Go to “Installing SFP Transceivers” on page 43 or skip to “Cabling the Switch” on page 46 if not installing SFP transceivers.
AT-GS908M, AT-GS916M, and AT-GS924M Switches Installation Guide Installing SFP Transceivers To install an SFP transceiver, perform the following procedure: Note The transceiver can be hot-swapped; you do not need to power off the switch to install a transceiver. However, you should always remove the cables before removing the transceiver. Note You should always install the transceiver before connecting the fiber-optic cables to it. 1.
Chapter 2: Installation 4. Slide the transceiver into the SFP slot until it clicks into place. See Figure 13. Figure 13. Inserting the SFP 5. Verify that the handle on the transceiver is in the upright position, as shown in Figure 14. This secures the transceiver and prevents it from being dislodged from the slot. SFP Transceiver Handle Figure 14. Positioning the SFP Handle in the Upright Position 6. Repeat Step 2 through Step 5 to install additional SFP transceivers.
AT-GS908M, AT-GS916M, and AT-GS924M Switches Installation Guide 7. Go to “Cabling the Switch” on page 46.
Chapter 2: Installation Cabling the Switch Observe the following guidelines when connecting twisted-pair and fiberoptic cables to the ports on the switch: 46 The connector on the cable should fit snugly into the port on the switch. The tab on the connector should lock the connector into place. Because the twisted-pair ports have auto-MDI/MDI-X, you may use straight-through twisted-pair cable to connect any type of network device to the switch.
AT-GS908M, AT-GS916M, and AT-GS924M Switches Installation Guide Powering On the Switch To power on the switch, perform the following procedure: 1. Lift up the retaining clip and insert the power cord into the AC power connector on the back of the switch, as shown in Figure 15. Figure 15. Plugging in the AC Power Cord 2. Lower the retaining clip over the AC Power Cord as shown in Figure 15. 3. Plug the other end of the power cord into a wall outlet. Warning Power cord is used as a disconnection device.
Chapter 2: Installation 4. Verify that the POWER LED is green. If the LED is OFF, see Chapter 3, “Troubleshooting” on page 49. The switch is now powered on and ready for network operations. For information on how to manage the switch, see the AT-GS900M Series CLI or Web Management Software User’s Guide.
Chapter 3 Troubleshooting This chapter contains information on how to troubleshoot the switch if a problem occurs. Note For further assistance, please contact Allied Telesis Technical Support at www.alliedtelesis.com/support. Problem 1: The POWER LED on the front of the switch is off. Solutions: The unit is not receiving power. Try the following: Verify that the power cord is securely connected to the power source and to the AC connector on the back panel of the switch.
Chapter 3: Troubleshooting Verify that you are using the appropriate category of twisted-pair cable: Category 3 or better for 10 Mbps operation and Category 5 and Category 5E for 100 and 1000 Mbps operation. Note A 1000Base connection may require 5 to 10 seconds to establish a link. Problem 3: The Link Activity LED for an SFP transceiver is off. Solutions: The fiber-optic port on the transceiver is unable to establish a link to a network device.
