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

“Bootrom Monitor

Mode Commands”

on page 3-35.

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, only the

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.
