Attach the two rack mount brackets to the sides of the switch using the eight bracket screws that come with the unit.
Chapter 2: Installation Figure 21. Attaching the Rack-Mount Brackets to the Switch (Continued) 3. Mount the switch in a standard 19-inch equipment rack using four equipment rack screws (not provided with the switch). Figure 22. Mounting the Switch in an Equipment Rack 4. Go to “Installing Optional SFP Transceivers” on page 42 or “Cabling the Switch” on page 45.
AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS Switches Installation Guide Installing the Switch on a Wall Only the AT-GS950/10PS and AT-GS950/16PS switches can be installed on a wall. Caution The AT-GS950/48PS is too heavy to be safely installed on a wall. To AT-GS950/10PS or AT-GS950/16PSinstall the switch on a wall, perform the following procedure: 1. Turn the switch over and place it on a table. 2. If the rubber feet are attached to the bottom of the switch, remove them using a flat-head screwdriver.
Chapter 2: Installation 4. Have another person hold the switch at the wall location where the switch is to be installed, while you use a pencil or pen to mark the wall with the locations of the four holes in the brackets. The switch should be oriented such that its front faceplate is facing up and is level to the floor. See Figure 24 on page 40. Figure 24. Marking the Screw Hole Locations 5.
AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS Switches Installation Guide 6. While another person holds the switch at the wall location, secure it to the wall using the four wall mounting screws. See Figure 25. Figure 25. Securing the Switch to the Wall 7. Go to “Installing Optional SFP Transceivers” on page 42 or “Cabling the Switch” on page 45.
Chapter 2: Installation 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. 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.
AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS Switches Installation Guide 4. Slide the transceiver into the SFP slot until it clicks into place. See Figure 27 Figure 27. Inserting the SFP 5. Verify that the handle on the transceiver is in the upright position, as shown in Figure 28. This secures the transceiver and prevents it from being dislodged from the slot. SFP Transceiver Handle Figure 28. Positioning the SFP Handle in the Upright Position 6.
Chapter 2: Installation For information on the cable specifications of the SFP, consult the documentation shipped with the SFP. 7. Go to “Cabling the Switch” on page 45.
AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS Switches Installation Guide 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. 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.
Chapter 2: Installation Powering On the Switch To power on the switch, perform the following procedure: 1. Plug the power cord into the AC power connector on the back of the switch, as shown in Figure 29. Figure 29. Plugging in the AC Power Cord 2. Plug the other end of the power cord into a wall outlet. Warning Power cord is used as a disconnection device. To de-energize equipment, disconnect the power cord. E3 Pluggable Equipment.
AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS 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 powered on and is operating properly. Verify that the twisted pair cable is securely connected to the port on the media converter channel and to the port on the remote network device. 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.
AT-GS950/10PS, AT-GS950/16PS, and AT-GS950/48PS Switches Installation Guide 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. Solution: There might be a duplex mode mismatch between the port and the network device.
