Chapter 10 Managing Your Cisco ONS 15530 System
Accessing System Images on TFTP Servers
Booting from a CompactFlash Card
The Cisco ONS 15530 can be booted, automatically or manually, from a variety of sources, including a
network server or Flash memory device. This section describes how to configure the Cisco ONS 15530
to boot automatically from an system image on a CompactFlash card. For an example of configuring the
system to boot manually from a CompactFlash card, see the “Updating System Images” section on
page 10-11.
To enable booting from a CompactFlash card, perform the following steps:
When you enter boot system commands, be careful not to insert extra spaces because they influence the
way the system interprets the command. Notice the difference in the following examples:
Examples
The following command correctly instructs the system to boot the image1 file in onboard Flash memory.
Switch(config)# boot system flash bootflash:image1
The following command incorrectly contains a space between “disk0:” and “image2.” The system finds
the filename field blank and so boots the first file on the CompactFlash card.
Switch(config)# boot system flash disk0: image2
Accessing System Images on TFTP Servers
