State—The State field displays one of the following:
— Offline—When the switch is “OFFLINE,” all ports are offline. The ports
cannot accept a login from an attached device or cannot connect to other
switches. You can configure this state through the Set Online State dialog
box. See “
” on page 166 for instructions.
— Online—All unblocked ports are able to connect with devices. You can
configure this state through the Set Online State dialog box. See “
” on page 166 for instructions. Note that the switch
automatically goes online after a power-up, an initial machine load
(IML), or initial program load (IPL).
— Coming online—This is a transitional state that occurs just before the
switch goes online. This state normally only happens briefly, unless there
is a problem reaching the online state.
— Going offline—This is a transitional state that occurs just before the
switch goes offline. This state normally only happens briefly, unless there
is a problem reaching the offline state.

No Link Status—If the Ethernet network connection between the HAFM
appliance and the switch is down, the Hardware View displays the front and
rear of the unit without FRUs. The switch Status table at the top of the
Hardware View changes to display the status (No Link) and the associated
reason with a yellow background. The name, description, and location fields
are blank.
The Reason field on the switch Status table displays one of the following
reasons when there are no links:
— Never Connected—A network connection was never established
between the switch and the HAFM appliance or the CTP card has failed.
Check the IP addresses, the Ethernet local area network (LAN) physical
connection between the switch and HAFM appliance, and other network
connection conditions.
— Link Timeout—The network connection that was established between
the switch and HAFM appliance has been lost. Check the IP addresses,
the Ethernet LAN physical connection between the switch and HAFM
appliance, IP addresses, and other network components.
