Chapter 1 Assigning the Switch IP Address and Default Gateway
Scheduling a Reload of the Software Image
When the switch is connected to a PC through the Ethernet management port, you can download or
upload a configuration file to the boot loader by using TFTP. Make sure the environment variables in
Table 1-5 are configured.
Scheduling a Reload of the Software Image
You can schedule a reload of the software image to occur on the switch at a later time (for example, late
at night or during the weekend when the switch is used less), or you can synchronize a reload
network-wide (for example, to perform a software upgrade on all switches in the network).
Note A scheduled reload must take place within approximately 24 days.
