Cisco Systems GRP-B manual Starting the System and Observing Initial Conditions

Starting the System and Observing Initial Conditions

Step 4 During the line card boot process, which occurs immediately after the GRP boots, observe the alphanumeric display LEDs on each line card.

The system attempts to boot identical line cards in parallel. Furthermore, the system boots line cards as soon as they are powered on and become available for a system boot. (The physical location of the alphanumeric display LEDs on the line cards is the same as on the GRP, which is shown in Figure 12.)

Refer to the appropriate line card installation and configuration note for complete details on line card display LED sequences.

You must meet the following criteria to successfully boot the GRP:

•Flash memory card or Flash disk is installed in Flash card slot 0

•Flash memory card or Flash disk contains a valid Cisco IOS software image

•Software configuration register is set to 0x2102.

The system automatically boots this Cisco IOS software image. The system then enters the setup facility, where you are prompted to perform a basic configuration of the system.

Otherwise, the system enters the ROM monitor and the appropriate prompt appears (rommon>).

Step 5 If the ROM monitor prompt (rommon>) appears, you must boot the Cisco IOS software image you want to use by entering the appropriate b command at the ROM monitor prompt:

•b—Boots the default system software from onboard Flash memory (if it is present in onboard Flash memory)

•b filename [host]—Boots the file filename from the server host using TFTP

•b flash—Boots the first file in the Flash memory card in Flash card slot 0

Caution To prevent system problems, use the b flash command option carefully; otherwise, you might instruct the system to boot a non-Cisco IOS software image from Flash memory. This command is not used with Flash disks.

•b slot0: filename—Boots the file filename from the Flash memory card in Flash card slot 0

•b slot1: filename—Boots the file filename from the Flash memory card in Flash card slot 1

•b flash disk0: filename—Boots the file filename from the Flash disk in Flash card slot 0

•b flash disk1: filename—Boots the file filename from the Flash disk in Flash card slot 1

Caution The b flash disk0: and b flash disk1: commands are only used from the ROM monitor (rommon>) prompt when the system fails to load normally. Do not use these commands from the router (router>) prompt.

While the system boots, the console screen displays a script and system banner similar to the following:

Cisco Internetwork Operating System Software

Step 6 Observe the system startup banner. When you start up an unconfigured system for the first time, the system automatically enters the setup facility, which determines which interfaces are installed and prompts you for configuration information for each one.
