Configuring the Serial Port

You can change the bit rate of the serial port labeled CONSOLE/MODEM on the HPDU. The default bit rate for both the console and modem operation is 115200 bps.

The HPDU supports the following devices through the serial interface:

• Computer or KVM product for console management.

• Analog modem for remote dial-in and access to the CLI.

• GSM modem for sending out SMS messages to a cellular phone.

Bit-rate adjustment may be necessary. Change the bit rate before connecting the supported device to the HPDU through the serial port, or there are communication problems.

You can set diverse bit-rate settings for console and modem operations. Usually the HPDU can detect the device type, and automatically apply the preset bit rate.

The HPDU indicates the detected device in the Port State section of the Serial Port page.

1. To configure serial port or modem settings, select Device Settings → Serial Port.
2. To change the serial port baud rate settings, click Connected device, and select any of the following settings to make the serial port enter an appropriate state.

   Serial Port Setting Description Automatic detection HPDU automatically detects the type of the device connected to the serial port. Select this option unless your HPDU cannot correctly detect the device type. Force console HPDU attempts to recognize that the connected device is set for the console mode. Force analog modem HPDU attempts to recognize that the connected device is an analog modem. Force GSM modem HPDU attempts to recognize that the connected device is a GSM modem.

3. Click Console Baud Rate and select the baud rate for console management.

4. Click Modem Baud Rate and select the baud rate for the modem connected to the HPDU.

   After the HPDU detects the connection of an analog or GSM modem, the modem settings appear in the web interface.

5. To configure the analog modem:
   1. Select Answer incoming calls to enable the remote access through a modem. Otherwise, deselect it.
   2. Type a value in the Number of rings before answering field to determine the number of rings the HPDU must wait before answering the call.
6. To configure the GSM modem:
   1. Enter the SIM PIN code.
   2. Select Use custom SMS center number if a custom SMS center is used.
   3. Enter the SMS center number in the SMS center field.
7. If needed, click Advanced Information to view detailed information about the modem, SIM, and mobile network.
8. To test whether the HPDU can successfully send out SMS messages with the modem settings:
   1. Enter the phone number of the recipient in the Recipient Phone field.
   2. Click Send SMS Test to send a test SMS message.
