Back Panel Management Software The switches come with the management software pre-installed. Although the three models have the same features, each has a different management software program.
Chapter 1: Overview or unshielded twisted pair cabling. The ports feature auto-MDI, which automatically configures the ports as MDI or MDI-X. This feature allows you to use straight-through twisted pair cables regardless of the wiring configurations of the ports on the end nodes. Note A switch port connected to an end node that is not using AutoNegotiation should not use Auto-Negotiation to set the speed and duplex mode, because a duplex mode mismatch might occur.
AT-GS950/8, AT-GS950/16, and AT-GS950/24 Switches Installation Guide has not established a link to an end node. The twisted pair port automatically changes to the redundant status mode when an SFP module establishes a link with an end node. A twisted pair port automatically transitions back to the active status when the link is lost on the SFP module.

Chapter 1: Overview Caution This procedure causes the switch to reboot. The switch does not forward network traffic during the reboot process. Some network traffic may be lost. 1. This will take up approximately 1 to 2 minutes before the switch comes back on line and is ready to switch Ethernet traffic again.

Orient the brackets against the sides of the switch as shown in Figure 9, and secure them to the unit with the eight brackets screws included with the switch. Figure 9. Attaching the Brackets to Install the Switch on a Wall 4.
Chapter 2: Installation Figure 10. Marking the Screw Hole Locations 5. Install the four plastic anchors included with the switch into the wall, at the locations marked in the previous step. The anchors require 0.635 mm (0.25 in.) holes. 6. While another person holds the switch at the wall location, secure it to the wall using the four wall mounting screws. See Figure 11 on page 37.

Go to “Installing Optional SFP Transceivers” on page 37 or “Cabling the Switch” on page 40. Installing Optional 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, always remove the cables before removing the transceiver.
Chapter 2: Installation Note You should always install the transceiver before connecting the fiber optic cables to it. 1. Remove the transceiver from its shipping container and store the packaging material in a safe location. Warning An SFP transceiver can be damaged by static electricity. Be sure to observe all standard electrostatic discharge (ESD) precautions, such as wearing an antistatic wrist strap, to avoid damaging the transceiver. 2. Remove the dust plug from an SFP slot. See Figure 12.
AT-GS950/8, AT-GS950/16, and AT-GS950/24 Switches Installation Guide 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.
Chapter 2: Installation Note Unnecessary removal and insertion of an SFP can lead to premature failure. For information on the cable specifications of the SFP, consult the documentation shipped with the SFP. 7. Go to “Cabling the Switch” on page 40. Cabling the Switch Observe the following guidelines when connecting twisted pair and fiber optic cables to the ports on the switch: The connector on the cable should fit snugly into the port on the switch.

AT-GS950/8, AT-GS950/16 and AT-GS950/24 Switches Installation 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.
Chapter 3: Troubleshooting Verify that the port is connected to the correct twisted pair cable. This is to eliminate the possibility that the port is connected to the wrong network device, such as a powered off device. Try connecting another network device to the twisted pair port with a different cable. If the twisted pair port is able to establish a link, then the problem is with the cable or the other network device. Verify that the twisted pair cable does not exceed 100 meters (328 feet).
AT-GS950/8, AT-GS950/16 and AT-GS950/24 Switches Installation Guide If the remote network device is a management device, use its management firmware to determine whether its port is enabled. Test the attenuation on the fiber optic cable with a fiber optic tester to determine whether the optical signal is too weak (sensitivity) or too strong (maximum input power). Problem 5: Network performance between a twisted pair port on the switch and a network device is slow.
