Technical Specifications Modem Serial Port Specifications Each CP card has a modem serial port (labeled RS-232) with a fully RS-232 compliant DB-9 connector. Note: For dust and electrostatic discharge (ESD) protection, keep the cover on the serial port whenever the port is not in use. The modem port can be used for attaching a modem to each CP card. The SAN Director 2/128 detects modems only during the power-on or reboot sequences, and automatically initializes them for operation. If modems are connected to an operating switch, a power on/off cycle, reboot, or fast reboot is required to detect the modem(s). If both modems are connected to the telephone line by a "Y" cable, the active CP card answers on the first ring; if the active CP card fails to answer, the standby CP card answers on the seventh ring. The pinouts for the modem serial port are shown in Table 24.
