BIOS Images
The GigaVUE-TA400E has a Basic Input/Output System (BIOS). The BIOS image is packaged with the software image. The BIOS contents are stored in flash memory, allowing the BIOS to be upgraded. There are two flash components, primary and secondary.
The following CLI command displays the two flash components and indicates the BIOS image from which the system booted using asterisks:
(config) # show version
1st flash version: v55.01.06.00p **
2nd flash version: v55.01.06.00p
If there is a component failure in the primary flash, the GigaVUE-TA400E boots from a backup golden BIOS image in the secondary flash. An SNMP trap can be configured to be sent when the system has booted from the secondary flash. The trap may indicate that the primary flash component needs to be serviced. The trap is as follows:
2ndflashboot: Secondary flash boot notification
