Initializing XSR Software
3-2 Software Configuration
• ETH 10/100/1000 LEDs turn ON and OFF a few times during initialization as the XSR
proceeds from bootrom to power up diagnostics to software image, then they remain ON or
OFF depending on the LAN type.
• ETHERNET Activity LEDs blink when frames pass on the LAN.
• COM Activity LED is OFF until the CLI comes up. Then it blinks ON/OFF during console
keyboard input or output.
• NIM LEDs are OFF until the CLI comes up. Then they are turned ON if a supported card is
present (T1/E1 or Serial), and the card passes the power-up diagnostics test.

XSR software initializes in two phases. A cold start (including power cycling) is marked by
diagnostic and router software phases. A warm start skips the powerup diagnostics and boots
to router software. First-time startup is a cold start with the following sequence of events:
• Basic hardware initialization of the processor, memory, and other components occurs.
• Bootrom Monitor mode is accessible now and can be entered by pressing a special key
combination within a 5-second interval. For more information, refer to
• Power-up diagnostics test the following hardware blocks:
–
RAM size is detected
–
On-board Flash size is detected
–
GigabitEthernet is checked
–
Ethernet on motherboard is checked
–
NIM cards 1 and 2 is checked
–
Real-Time Clock are checked
–
Front panel LEDs are set to reflect current status
• Diagnostics test results are saved for later use by system software.
• The software image in Flash memory is verified by checksum.
–
If no valid image exists in
flash:
or
cflash:
, Bootrom Monitor mode is acquired.
–
If the default file (xsr3000.fls) is not found as specified in Bootrom mode, an FTP/TFTP
server as defined in network parameters of Bootrom mode is queried.
–
If the image is not found remotely, initialization is suspended in Bootrom mode.
• A valid image in Flash memory, if present, is decompressed.
• The decompressed software image is loaded into RAM.
• Execution is passed to the software image.
• The operating system is started.
• The Flash startup configuration files (startup-config, private-config) become the running
configuration.
• All software modules are initialized. If an error occurs when processing startup-config, the
CLI will continue processing the file until the end. If the file contains more than one error,
Note: Optionally, you can create a boot-config file to identify the name of a firmware file from which
the XSR boots. Refer to the boot system command in the XSR CLI Reference Guide for more
information.
