Mediant 1000B SBA
30.3 Upgrading or Recovering with Online Monitoring
using EMS
You can monitor the SBA upgrade and recovery process using Emergency Management
Services (EMS). EMS is a technology that supports remote management and system
recovery for servers that are not accessible through an in-band connection. An in-band
connection is a connection between two computers that relies on a standard network such
as a LAN or the Internet, and on standard remote administration tools such as Remote
Desktop or Telnet. You can use this type of connection to remotely manage computers
only if both the local and remote computers are in a functional state and accessible on the
network.
EMS redirects text output to the out-of-band connection. An out-of-band connection is a
non-standard connection between two computers such as a serial port connection, and is
useful when a remote server cannot access the network or is not fully functional. EMS
provides a command-line environment for managing a server through the out-of-band port.
The capability of redirecting text output is also known as console redirection.
Notes:
• The OSN3 does not provide a direct monitor connection (Micro HDMI port), and
therefore, the serial port is used for online monitoring (using EMS).
• For the Mediant 1000B OSN3B/OSN4 serial interface port (micro-USB) to be
operational, you must download a special USB driver from the Internet. Download this
driver at

To monitor SBA upgrade and recovery using EMS:
1. Open (using a text editor such as Notepad) the RecoveryUtil.ini file and then set the
RecoveryStartType parameter to 1, as shown below:
[Execution] RecoveryStartType= 1
2. Save and close the RecoveryUtil.ini file.
Do one of the following:
• OSN3B and OSN4: Using the supplied micro USB to USB cable adapter,
connect the micro USB connector end to the Mediant 1000B OSN serial port (
), and then connect the other end of the cable (USB) to the serial interface
port on your PC.
