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.
