Setting Up and Installing Modems Using High Availability Connectivity High availability of the modem connection can be ensured by connecting a separate modem to each CP card and then connecting both modems to a shared telephone line (see Figure 29). This ensures an available telephone connection to the active CP card even if a failover occurs; however, it is necessary to log back in after a failover. When both CP cards are connected to a shared telephone line, callers are automatically dialed in to the active CP card, which answers on the first ring. If the active CP card cannot answer for any reason, the standby CP card answers on the seventh ring and allows login to proceed. Note: If a modem connection is set up, connecting a modem to each CP card is recommended. 152 SAN Director 2/128 Installation Guide
