edge switch 2/16 service manual 1–27
General InformationI
• Online - when the switch is set online, an unblocked port and all unbypassed ports
are awaiting device login and are able to attach to a device. This state is
configured through the Set Online State dialog box or following an IML.
• Offline - when the switch is set offline, all ports are offline and cannot accept a
login from an attached device that requires a switch connection. This state is
configured through the Set Online State dialog box.
• Coming online - this is a transitional state that occurs just prior to the switch
going online. Unless a problem occurs, this state appears only briefly. The switch
automatically transitions through this state after a power-up or reset procedure.
• Going offline - this is a transitional state that occurs just prior to the switch going
offline. Unless a problem occurs, this state appears only briefly.
LED Emulation
At the Hardware View for the selected switch, simulated LEDs illuminate on FRUs
and adjacent to port SFPs to emulate the operation of LEDs on the corresponding
hardware. Simulated PWR and ERR LEDs also illuminate to emulate the operation of
LEDs on the corresponding switch front panel. For an explanation of LED operation,
refer to FRU Status LEDs.
Product Manager Status Symbols
A status bar at the bottom of the window displays a colored symbol (green circle,
yellow triangle, red diamond with yellow background, or grey square) that indicates
the worst-case status of the selected switch. The meaning of the status symbol is
consistent with the icon explanations in
Table 1–1.
As an example, for a single SFP, fan, or power supply failure, a blinking red and
yellow diamond displays at the FRU illustration in the Hardware View. However, the
status bar displays a yellow triangle to indicate degraded operation. If a blinking red
and yellow diamond displays over multiple FRUs, the status bar displays a red and
yellow diamond, indicating a critical failure and the switch is not operational.
The following colored symbols overlay graphical FRUs to represent failed or
degraded status for the corresponding switch FRU.
• Failed FRU indicator - a blinking (color reversing) red and yellow diamond
overlaying a FRU indicates the FRU failed and immediate service is required.
