4.4 Connecting the Console Terminal
Hardware Installation
A console cable kit is provided with the SDM-8400 product package to connect the SDM-
8400 to the console terminal. This is a standard TIA-232 (V.24) straight-through cable
with DB-9 female connectors at both ends (Ordering part number: 161-0703-001). See
“Console Port” on page 5-8 for details.
To connect the console terminal to the SDM-8400 unit:
1. Install one end of the console cable onto the SDM-8400 console port, labelled CSL
on the rear panel. Refer to Figure 5-1 on “Rear View of the SDM-8400 UAC (8-port
version)” on page 5-2.
2. Connect the other end of the console cable to the RJ-45 female side of the terminal
adaptor.
3. Plug the DB-9 female side of the terminal adaptor into a COM port on the console
terminal or PC, or to a modem for dialup connection to a remote console.
4.4.1 Important Console and Modem Settings for Startup
The console port performs autobaud detection when in auto-sensing mode. The SDM-
8400 will set the speed of the console port as soon as it detects an active connection.
Caution: For trouble-free startup, you should set the console terminal and
modem as follows:
• Console terminal: The default console speed is 9600 bps during bootstrap initialization,
boot sector validation and system initialization. Set your console terminal
emulator to 9600 bps to view all SDM-8400 system status messages onscreen
during the initialization sequence (described on “System Status on Powerup”
on page 4-6).
• Modem: Configure your modem with the following AT commands:
• at&d0 to ignore DTR. The SDM-8400 cannot supply DTR to the modem when in
auto-sensing mode (the default setting).
• ats0=1 for Auto Answer mode
• at&w0 to save the modem configuration.
Once the initialization sequence has completed successfully, the SDM-8400 enters autosensing
mode automatically. At that point, you can change your console speed, if desired.
• Available console speeds are 1200, 2400, 4800, 9600, 19200, 28800, 38400,
57600 and 115200 bps. The equipment you connect to the console port must
operate at one of these speeds.
4.4.2 Activating the Console Connection
To activate the console connection:
1. Ensure that the SDM-8400 unit has successfully powered up with no system status
errors (see “System Status on Power-up” on page 4-6).
