5.5 Booting Device
When the Ethernet Connection Blade Module is connected to the local terminal, the device Ethernet
Connection blade Module goes through Power On Self Test (POST). POST runs every time the device is
initialized and checks hardware components to determine if the device is fully operational before
completely booting. If a critical problem is detected, the program flow stops. If POST displayed on the
terminal and indicate test success or failure.
As the device boots, the boot-up test first counts the device memory availability and then continues to
boot. The following screen is an example of the displayed POST.
------------ Performing Power-On Self Tests (POST) --------------
System SDRAM Test..........…………….........PASS
CPU Self Test......................………………….PASS
UART Loopback Test.................……………..PASS
Flash Memory Initialize............……………….PASS
Flash Memory Checksum Test.........………...PASS
PCI Bus Initialize and Test........………………PASS
System Timer Test..................………………..PASS
I2C Bus Initialize and Test…………………….PASS
Ethernet Physical Test…………………………PASS
---------------Power-On Self Test Completed---------------------------
Press [Ctrl+B] to enter back door or any key to continue…
The boot process runs approximately 60 seconds.
The auto-boot message displayed at the end of POST (see the last line) indicates that no problems were
encountered during boot. During the BootROM Back Door Command Line Interface can be used to
run special procedures. To enter the BootROM Back Door CLI, please press Ctrl+B within the first two
seconds after the auto-boot message is displayed. If the system boot process is not interrupted by
pressing Ctrl+B, the process continues decompressing the loading the code into RAM. The code starts
running from RAM and the list of numbered system ports and their states (up or down) are displayed.
After the device boots successfully, a system prompt is displayed which is used to configure the device.
However, before configuring the device, ensure that the latest software version is installed on the device.
If it is not the latest version, download and install the latest version is necessary. For more information on
downloading the latest version see the section “Software Download”.
