Setting the LAN IP Addresses
Figure 2-3 Hardware Required for Local LAN Connections
Note The PXM UI-S3 card shown in Figure 2-1 has two LAN ports. In the current software release, only the
LAN 1 connector is enabled for LAN communications. Communication through the LAN 2 connector is
disabled.
Before you can manage the switch through the PXM45 LAN port, you must first assign an IP address to
the LAN port. The LAN or disk IP address is the IP address for the Ethernet LAN port on the active
PXM45. The LAN IP address is also called the Disk IP address because it is stored on the PXM45 hard
disk. However, the IP address for the Maintenance Port is also stored on the hard disk and must be
different, so this section refers to this address as the LAN IP address.
Note To enable LAN connectivity to the active PXM45 card, you must configure a LAN IP address. The boot
IP address cannot be used to access an active PXM45 card. If you want to assign only one IP address for
LAN access, assign the same IP address to the boot and LAN IP addresses.
Tip The significance of the Disk IP address for the LAN Port is that it is stored on the hard disk and is not
available until the runtime software is loaded on the PXM45 card and the card is active. To access the
LAN port over Ethernet when a PXM45 is operating in boot or standby mode over, you must use the
Boot IP address.
The LAN IP address can be set to match the boot IP address when only one IP address is available, or it
can be set to a unique address to support access to the standby PXM45 during regular operation. For
more information on how the boot and LAN IP addresses are used, see Chapter 1, “Guidelines for
Creating an IP Address Plan.”
