Edge Switch Element Manager user guide 47
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.
• Protocol Mismatch—The switch and the HAFM appliance are not at compatible software
release levels. Update the HAFM software version or your product’s firmware so that they
are at compatible levels.
• Duplicate Session—A link has previously been established between the switch and
another instance of the HAFM appliance. Connect to the previously established HAFM
appliance from the HAFM login screen.
• Unknown Network Address—The address defined for the switch in HAFM could not
be found in the domain name server (DNS). Either the name was mistyped when the switch
was added to the application, or the name was not available from the DNS. Check the
network IP address for the switch definition in HAFM by right-clicking the product icon and
selecting Properties. The IP address displays in the Network Address field.
• Incorrect Product Type—The product at the configured network address is not a switch.
Verify address, configuration, and product type.
• Link Disabled—The IP address of an open Element Manager was removed from the
discover list.
Status bar status indicator
The status bar displays a colored status symbol that indicates the overall operating status of the
switch unit. The operating status depends on hardware component failures, which are indicated by
status symbols that display over component graphics in the Hardware View. See ” Hardware
View ” on page 46 for the meanings of status symbols in the status bar.
The status bar indicates the switch operating status based on component failures. For example, a
yellow triangle displays in the status bar to indicate a degraded switch. However, if a blinking red
and yellow diamond displays over both power supplies, the status bar displays a red and yellow
diamond, indicating a failure that requires immediate attention.
Monitoring hardware operation
You can determine hardware component operating status and states by viewing the simulated light
emitting diode (LED) indicators and status symbols, such as flashing red and yellow diamonds and
yellow triangles, that display on hardware components. These simulated LEDs and status symbols
reflect the state of the actual hardware as changes occur. Corresponding or additional descriptions
of hardware status and states also display when you double-click components to display Properties
dialog boxes.
