Issue Resolution
IP address is not received from DHCP server If the switch does not receive an IP address from an upstream device operating as a DHCP server, make sure that the
upstream device is operating as a DHCP server and again follow the procedures to set up the switch in
Chapter 1, About
the Switches .
Switch has wrong IP address If the switch is installed in your network but you cannot access the switch because it has the wrong IP address, assign a
new switch IP address.
Refer to Access Direct Managed Mode on page 237 to assign the IP address, and then update the
switch IP address on the Device Manager Express Setup window.
