Power supply specifications: ¦ 40 to 60V, 48V nominal ¦ supports either positive grounded or negative grounded operation ¦ a 15Amp certified/listed circuit breaker is required for circuit protection Supply cable specifications: ¦ three-core cable is required ¦ minimum core size: 3.3mm2 (12 AWG) high strand count copper wire ¦ minimum cable rating: 600V, 90 degrees C Warning Disconnect the power supply cable before starting this procedure. 1. Remove the transparent protective terminal cover. 2. Strip the supply cable wires to expose 7.5mm (0.31 in.) of bare conductor. Terminate the wire with a nylon insulated solderless ring tongue terminal, JST FN5.5-5 or equivalent, using a crimp tool. 3. Connect the ground wire to the ground terminal. Use the diagram on the rear panel of the switch to identify terminals. Tighten the terminal to between 2.4 and 4.0 Nm (21.3 and 35.4 lbf in). Caution Check that the PSU terminals are wired to the correct polarity. You will damage the PSU if you incorrectly connect it. 4. Connect the positive feed to the + (positive) terminal and the negative feed to the - (negative) terminal. Tighten the terminals to between 2.4 and 4.0Nm (21.3 and 35.4 lbf in). Note that the DC return input terminal must be connected as an Isolated DC return (DC-I). Removable Power Supply and Fan 5. Ensure there are no exposed cable strands. 6. Replace the cover. You must replace the transparent plastic terminal cover before continuing. 7. Secure the supply cable to the rack framework or a similar object to ensure that connections are isolated from any force applied to the cable. 8. Ensure the circuit breaker for the supply circuit and the Run/Standby control on the PSU are off. Press and release the Run/Standby control so that it is not pushed in (which is the Off position). 9. Connect the supply cable wires to the circuit breaker. 10. Turn on the PSU by pushing in the Run/Standby control. 11. Confirm that the switch is receiving power. Check that at least one of the PSU LEDs on the front panel of the switch is lit green. If no LEDs light, refer to the Hardware Reference for troubleshooting information. Installation Guide Checking LEDs PWR01 PWR02 LEDs on PSUs, fans, and the front panels of switches indicate the operational status of the devices. After you have installed a PSU or fan and have powered on the switch, check the LEDs to verify operation by using the following tables. The following table describes LEDs on the PWR01 and PWR02 power supply units. LED FAULT PWR GOOD State Red Green Description The temperature on the PSU has exceeded the limit of 75. C (167. F), or the fan failed. A PSU is installed in the switch and is delivering power. PWR05 The following table describes LEDs on the PWR05 power supply unit. LED State Description Green AC input voltage is within 90-264VAC, 47-63Hz. ~ Off AC input voltage is outside the acceptable range. Green DC output voltage is within 12V +/- 10%. Off DC output voltage is outside the acceptable range. Red A fault has occurred. There is either a fan failure, or the temperature has exceeded its limit of 70.C (158.F). Off No fault conditions detected. FAN01 The following table describes LEDs on the FAN01 fan-only module. LED State Description FAULT Red The fan has failed. FAN03 The following table describes LEDs on the FAN03 chassis fan module. LED State Description FAN STATUS Red The fan has failed. Removable Power Supply and Fan Switch The following table describes how LEDs on the switch report operations and faults with installed PSUs and FOMs. LED State Description PSU 1 Green The PSU is installed and supplying power to the switch. and The voltage output is within specification. PSU 2 Red One of the following: • The PSU is installed in the switch, and a fan has failed or the PSU has exceeded its recommended temperature threshold of 70.C (158. F). • A FOM is installed in the switch and a fan has failed. The x900-12XT/S and the SwitchBlade x908 switches do not support FOMs. • The bay is empty. Applies to AT-8948, AT-9924Ts, x900-24XT, x900-24XT-N, and x900-24XS switches which require a FOM when only one PSU is installed. • Dual PSUs are installed, but the PSU is not receiving power. Off A FOM is installed and operating at an acceptable speed. For AT-9924T, x900-48FE, x900-48FS, and SwitchBlade x908 switches, a blanking plate is installed. Installation Guide Removing a Power Supply Unit or Fan Follow these instructions to remove a PSU, chassis fan module or FOM. Before you begin ¦ Read the safety information for the switch. Safety information is in the x900 Series Switch and SwitchBlade® x908 Installation and Safety Guide. You can download this document from ¦ Gather necessary tools and equipment. You will need an appropriate flat-bladed or Phillips (#1) screwdriver to tighten or loosen the captive screws. Caution Follow correct anti-static procedures. Failure to do so could damage the PSU, fan, or switch. If you are unsure ...
