Data Domain DD9800 System Installation and Storage Expansion Guide

Enable administrative communication

For HA pairs, administrative communication must be enabled on both nodes.

The administrative interfaces are located on the management module on the rear of the chassis. These interfaces are for management network traffic only. Do not use these interfaces for data traffic.

1. Connect an administrative console to the serial port on the back panel of the system.
2. NOTE You must have 115200 baud rate for the DD9800 system to work properly; 9600 baud rate will not work for the DD9800 system.
   Launch a terminal emulation program from your computer and configure the following communication settings:

   Table 1. Communications settings

   Setting	Value
   Baud rate	115200
   Data bits	8
   Stop bits	1
   Parity	None
   Flow control	None
   Emulation	VT-100

3. Select Enter on your keyboard to activate the console.
   NOTE If you do not see the prompt on your terminal to log in, then complete Step 4.
4. In the front of theDD9800 system, press the power button to power on the system. Check that the front blue power LED (with the circle with a dot) also turns on.

   

   • 1. Power LED
   • 2. Power button
5. NOTE The initial username is sysadmin and the initial password is the system serial number.
   Log into the Data Domain console using the sysadmin username.

   localhost.localdomain login: sysadmin

6. Enter the default password, which is the system serial number (SSN). The SSN is on the attached tag on the rear panel of the system. See the rear panel of the DD9800 system for the SSN tag.

   Password: system_serial_number

   NOTE Configuring an HA pair sets the system password on the standby node to match the system password on the active node, however, that synchronization is not set until the HA configuration is complete. If the HA configuration fails, or if there is a need to access either node before the HA configuration is complete, use the serial number of each node as the password.

For Data Domain HA systems, SSH keys created on the active node take 30 seconds to one minute to propagate to the standby node.
