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, Getting Started
.
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 146 to assign the IP address, and then update the switch IP address on the
Device Manager Express Setup window.
