Appendix A Indicators

Indicators on the Switch Panel

Different switch models have different indicators on their panels. This section describes indicators on the S5700-LI supporting a single power module and the S5700-SI supporting double power modules. For the states and meanings of other indicators on other switch models, see "Indicator Description" in the Hardware Description.

Table 13-1 Indicators on an S5700-LI supporting a single power module

Indicator	Color	Description
PWR: internal power supply indicator	-	Off: The switch is not powered on.
	Green	Steady on: The power module is supplying power normally.
	Yellow	Steady on: The internal power module is faulty, and the switch is powered by the RPS system.
SYS: system status indicator	-	Off: The system is not running.
	Green	Fast blinking: The system is starting or is copying the system software and configuration file from a USB flash drive during a USB-based upgrade. Slow blinking: The system is running normally.
	Yellow	Blinking: The switch is in sleeping mode. During a USB-based upgrade, this indicator blinks after the switch downloads required files and restarts. At this time, the upgrade is successful and you can remove the USB flash drive.
	Red	Steady on: The system does not work normally after registration, or a fan alarm or temperature alarm has been generated. Blinking: The system cannot be upgraded after a USB flash drive is inserted. The USB-based upgrade failed.
Mini USB indicator	Green	Off: The Mini USB port is disabled, and the console port is enabled. Steady on: The Mini USB port is enabled. When the Mini USB indicator is steady green, the console port indicator is off.
Console port indicator	Green	Off: The console port is disabled, and the Mini USB port is enabled. Steady on: The console port is enabled (default state). When the console port indicator is steady green, the Mini USB indicator is off.
