IMPORTANT: Power protector software requires the communications port to be appropriately cabled to the host computer. CAUTION: Only one communications port can be connected to the host computer. Connecting more than one will result in unexpected UPS behavior. If an option card is installed, the serial and USB communications ports are automatically disabled. For information about serial port pin assignment, see "Serial communications port pin assignment (on page 36)" . Connecting the USB communications port Connecting the Network Transient Protectors CAUTION: To avoid damaging the equipment, use the Network Transient Protector with a standard telephone line only, not with a digital PBX. NOTE: Do not connect any telephone or fax/modem equipment (RJ-11) to the 230V models; only connect network cable (RJ-45) to the 230V models. To protect equipment against surges over a network data line: 1. Connect the network wall jack to the UPS Network Transient Protector IN jack. Installation 15
