Upgrading the Boot Helper (Boot Loader) Image

Troubleshooting the Port Adapter or Service Adapter

Check the following to help isolate a problem with the port adapter or service adapter:
Upgrading the Boot Helper (Boot Loader) Image
The boot helper (boot loader) image resides in flash memory and contains a subset of the Cisco IOS
software. This image is used to boot your router from the network or to load Cisco IOS images onto the
router. This image is also used if the system cannot find a valid system image.
Your boot helper (boot loader) image should correspond to the Cisco IOS release that is running on your
router.
Note The Cisco 7201 router requires the c7200p-kboot-mz boot helper ima g e .
To upgrade your boot helper (boot loader) image, obtain the most current boot helper image through
Cisco.com and copy the new boot helper image to flash memory on your router. Access Cisco.com on
the web and, if you are a registered Cisco.com user, click Login at the top right of the page. If you are
not a registered Cisco.com user, you can register by clicking Register at the top right side of the
Cisco.com page. After you have logged in, click Support. Click Download Software and choose the
appropriate link.
To obtain a boot helper (boot loader) image from Cisco.com and upgrade your bootflash, do the
following:
Step 1 Download the boot helper (boot loader) image from Cisco.com to a Trivial File Transfer Protocol
(TFTP) server.
Step 2 Reformat the flash memory on your router as follows:
Router# format bootflash:
Format operation may take a while. Continue? [confirm]
Format operation will destroy all data in "bootflash:". Continue? [confirm]
Formatting sector ...
Format of bootflash:complete
Note Reformatting flash memory erases the current flash memory contents.

Symptom Possible Cause Possible Solution
Port adapter or
service adapter
ENABLED
LED is off.
The port adapter
or service adapter
might have pulled
away from the
system board.
Reseat the adapter in its slot (you do not have to turn off the
system power when removing or replacing port adapters and
service adapters). After the system reinitializes the interfaces,
the ENABLED LED on the port adapter or service adapter
should go on.
If the ENABLED LED remains off, the system detected a
processor hardware failure. (This LED should be on in normal
operation.) Contact a service representative for instructions.
