A modem (not provided)
•
A desktop or notebook computer (not provided)

Setting the Serial Console Speed for the Switch
Before you can connect the switch to a modem, the switch’s serial console speed must
be set to 115200 baud.
NOTE: The default serial console speed is 9600 baud.
To change the serial console speed:
1. Power on the switch. (If the switch is an EX8208 or EX8216 model, see Powering On
an EX8200 Switch.) The loader script starts.
2. You are prompted with:
Hit [Enter] to boot immediately, or space bar for command prompt.
Press the Spacebar to pause the switch in the loader state (after the Junos OS has
loaded on the switch but before the software starts).
