Setting the Switch's IP Address
Each switch must be assigned its own IP Address, which is used
for communication with an SNMP network manager or other
TCP/IP application (for example BOOTP or TFTP). The switch's
default IP address is 10.90.90.90. You can change the default
switch IP address to meet the specification of your networking
address scheme.
