4-18 Compaq ProLiant CL380 User Guide Installing an Uninterruptible Power Supply In the event of a power loss, the ProLiant CL380 can take up to 35 minutes to completely shut down. To guarantee that no data is lost during that time, use an uninterruptible power supply (UPS) system. When installing a UPS, there are two supported cabling configurations. The cabling configuration is dependent on the selected UPS units. In the first cabling configuration, one Compaq R6000 UPS is used with an optional Multiserver UPS card installed. The Multiserver UPS card allows the UPS to communicate with both server nodes. In the second configuration two Compaq R3000 UPS units are used. Each R3000 UPS connects to a serial port on a server node. Connecting a Compaq R6000 UPS To connect a single Compaq R6000 UPS unit with a Multiserver card to a ProLiant CL380, perform the following steps: NOTE: See Figure 4-21 for a view of this UPS cabling. Connecting Power Supply Cables 1. The Y power splitter cable connects from the left shared storage area power supply to the power supply in server node 2 (bottom). 2. The Y power splitter cable connects from the right shared storage area power supply to the power supply in sever node 1 (top). Connecting Serial Cables NOTE: For information on adding a Multiserver UPS Option Card to a UPS, refer to the Multiserver UPS Card Installation Guide. 1. The serial cable connects from a COM port on server node 1 (top) to a serial connector on the UPS. 2. The serial cable connects from a COM port on server node 2 (bottom) to a second serial connector on the UPS.
