Applying Power
The following sections detail the installation of the field replaceable power supply units (PSU) and the connection to the AC Line to power the Onyx FHM.
WARNING: The AC Line of the Onyx FHM can present dangerous voltage. Contact with the line voltage can result in pain or injury.
1. Verify that the chassis ground of the Onyx FHM is connected to an earth ground before connecting AC Power Cable to the Onyx FHM unit.
2. Verify that the AC Line has a quality signal ground integrated with a circuit breaker prior to applying AC Line Power to the Onyx FHM.
3. Ensure that line voltage is not present when plugging the AC Power Cable to the PSUs of the unit. Only plug units into AC Line voltage after they are connected to the Onyx FHM.
The PSUs are pre-installed in the Onyx FHM. The PSU is a hot swappable field replaceable unit (FRU) and can be replaced while the equipment is operating if the remaining (second) PSU is installed and in operation.
The following instructions detail how to install a new PSU field FRU in the Onyx FHM.
PSU Replacement
WARNING: Shock hazard! For safety, disconnect power input cable from the power supply unit before servicing the equipment.
PSU FRU Removal
Locate the release tab on the PSU FRU and press and hold the blue release tab to the right to unlock the PSU from the power bay.
While holding down the release tab, grip the PSU's handle and firmly pull it out of the power bay.
PSU FRU Removal
PSU FRU Installation
Align the new PSU with the empty power bay, ensuring the PSU’s power connector is in the correct orientation (see Figure 24).
Carefully slide the new PSU into the power bay and gently push until the front surface of the PSU is flush with the front surface of the case.
An audible click will be heard when the PSU is installed correctly. The PSU will not go in all the way if it is inserted in the wrong orientation.
CAUTION: If the insertion of the PSU results in either significant resistance or a hard stop, remove the PSU and inspect it for correct orientation and/or damage. If damage is found or insertion issues persist, contact your supplier for replacement of the PSU. Do not attempt to repair a damaged PSU.
PSU FRU Installation
Connection of AC Power
Ensure there is enough power available on the selected electrical circuit to supply the Onyx FHM. The maximum system power consumption is 188.22 watts with an input voltage of 100-240V AC. It is recommended to ensure that enough power is available from the power distribution system prior to installation.
The Onyx-FRU is designed to support 1 + 1 power redundancy. Ensure that both PSU FRUs have been properly installed before powering up the equipment.
Insert the AC PSU Cable Receptacle of 1 pc. of the included power cords into the AC PSU ensuring that it is fully inserted.
Insert the standard AC Plug into the desired AC outlet. If necessary, switch on power strip that PSU(s) are plugged into.
Verify that the power supply is operating. The LED on the PSU will illuminate Green designating normal operation.
