Why won’t the switch power on?
• The 480T routing switch uses a digital power supply with surge
protection. During a power surge, the protection circuits turn off the
power supply.
• To reset, unplug the switch for 1 minute, plug it back in, and restart
the switch.
• If this does not work, try using a different power source (different
power strip or outlet) and power cord.
Using the Command-Line Interface
Why won’t the initial Welcome prompt display?
• Check that your terminal or terminal emulator is correctly
configured.
• For console port access, you may need to press Enter several times
before the welcome prompt appears.
• Check the settings on your terminal or terminal emulator. The
settings are 9600 baud, 8 data bits, 1 stop bit, no parity, XON/OFF
flow control enabled.
Why won’t the SNMP Network Manager access the device?
• Check that the device IP address, subnet mask, and default gateway
are correctly configured, and that the device has been reset.
• Check that the device IP address is correctly recorded by the SNMP
Network Manager (refer to your user documentation for the
Network Manager).
• Check that the community strings configured for the system and
Network Manager are the same.
• Check that SNMP access was not disabled for the system.
