Chapter 4. Updating Software
This chapter contains customer procedures for downloading software upgrades to
the 8270 flash EEPROM. Due to periodic updates to this code, customers should
check for more recent code (a higher number) than that which is currently installed
on your switch.
Note: The 8270 is not operational during a reset. Before starting this procedure,
make sure that the network will not be affected.
The Interface Description on the Switch Information panel shows the hardware and
software version of the 8270. The port microcode level applies to code related to
physical port function.
