3 Operating the Unit
This chapter describes how to operate the unit by accessing the board with the available tools. The boot-
loader is part of the Software on the AM4904 and is also described.
The Software accomplishes operation of the switching hardware as well as the MCMC SW and is therefore also
referenced as Firmware. It is pre-installed on the system and can only be updated by a dedicated update pro-
cedure. This chapter describes all parts of the Firmware and introduces the update procedure.
3.1 Board Access
The board provides access through the following externally accessible management interfaces.
The serial Interface is the low level debug interface. If connected to the front serial connector, the user will
have access to the linux shell. The shell provides tools and applications used for example to manage the sys-
tem, the CM and the FASTPATH switching software.
Serial connection port settings are:
• 115,200 bps (serial speed might be different for customized board variants)
• 8 bit, no parity, 1 stop bit (8N1)
• no flow control
