2-18 Installing the Hub Installing an Optional Modem If you want to access the hub via a Hayes modem, you must prepare the modem correctly for use with the hub. Follow these steps: 1. If necessary, change the hub's baud rate to match the modem's baud rate. Refer to the preceding section, "Changing the Serial Port's Baud Rate," for instructions on changing the baud rate. NOTE: Before you install a modem, you should set a password to restrict access to the hub. 2. Log out from the hub by entering the logout command. Type: logout [Enter] 3. Be sure the modem is turned off. 4. Connect the modem to the hub's serial port. The serial port requires a female DB-9 connector. The modem requires a male DB-25 connector. 5. Power-on the modem. Within 2 minutes the modem will be programmed to auto-answer within two rings. The modem is ready to respond to the hub when the AA LED comes on.
