Upgrading Hardware and Software

47

Testing typical device connections on terminals, printers, or hosts.

Testing the connectivity with specific bridge/routers.

Custom checks based on applications and typical network use.

For instance, you can check normal operation over the network and perform file transfers, as well as run traces on specific routes or check routing tables.

11Accept or reject the upgrade.

If your software upgrade completed successfully, accept your upgrade using:

bcmsysupgrade -s:accept -new_hw <device>

If the upgrade process failed to meet your verification criteria, reject your upgrade using:

bcmsysupgrade -s:reject -new_hw <device>

The bridge/router is rebooted using the previous version of software.

12NETBuilder II with CEC only — (The CEC module is not supported in software version 11.1. However, you can use the utilities to upgrade your CEC module to software version 10.1 or earlier.) If the upgrade is successful, and if you have not already done so in step 2, upgrade the CEC firmware by following these steps:

a Make sure there is a floppy diskette with write access in the floppy drive on the bridge/router. Make sure that the contents of the diskette you intend to use can be overwritten. Perform a manually recoverable firmware upgrade using the option -m if you do not want the floppy diskette formatted.

bUpgrade your firmware to version 2.6 using:

bcmsysupgrade -s:upgrade_cec_fw -V:<version you are upgrading to>

<device>

After the firmware has been upgraded, the bridge/router reboots.

13NETBuilder II only — If the upgrade is successful, and the NETBuilder II bridge/router has a multiport HSS module or an MP module, upgrade the firmware for all these modules using:

bcmsysupgrade -s:upgrade_io_fw -m <device>

The bridge/router reboots after the firmware is upgraded.

Manual Recovery This section describes how to perform a software and hardware upgrade with manual recovery. See Chapter 3 for the memory requirements for manual recovery.

Whenever you specify an option with bcmsysupgrade (such as -m and -new_hw), you must repeat that option for all steps in the procedure. See Table 4 on page 40 or “bcmsysupgrade” on page 81 for a list of the options available to use with the bcmsysupgrade utility.

To upgrade the bridge/router, follow these steps:

1Back up your current software to the NMS using:

bcmsysupgrade [options] -s:from_nb -m -new_hw <device>

where [-options] lets you specify -EncryptionLicenseRead that indicates you have read and understand the encryption license agreement notice and <device> is the IP address or hostname of the bridge/router you are upgrading.
