Hardware Overview
Understanding the Software Loading
This section describes the two methods for loading software.
Loading from Flash RAM
Once the Access Server 316 completes self-tests, it checks for Flash RAM. If there
is a valid Flash RAM, the Access Server 316 begins the boot sequence to load the
software from Flash RAM. The Seven-segment display will display three
horizontal segments during this Flash RAM loading phase.
If the Access Server 316 does not have Flash RAM, or if the name of the image in
Flash RAM does not match the image name the Access Server 316 is attempting to
load, it proceeds to a network load.
If a device is connected to the console port, the Access Server 316 can display
status messages while the boot sequence is running. Status messages indicate the
Ethernet address of the Access Server 316, the name of the load image it is looking
for, and the current stage of the boot process.
Loading from the Network
If you do not want to load the software from Flash RAM, you can press the
system reset switch during load from Flash RAM (three horizontal segments
displayed on the Seven-segment display). When the system reset switch is
pressed, the Flash RAM load will be aborted and the software is downline loaded
from a load host.
When the Access Server 316 notices that the system reset switch depressed during
a load from Flash RAM, it will rapidly blink the LED to acknowledge the pressed
system reset switch (this may take several seconds). Once the LED begins rapidly
blinking, you may release the system reset switch and the firmware will go on to a
network boot sequence. For more information on display codes for Flash RAM
(See section titled
Seven-Segment Display Codes
on page 7-7).
