Mini USB port

The mini USB port is connected to a console for on-site configuration. When both the Mini USB and console port have a cable connected, only the Mini USB port works.

Indicator Description

In V200R007 and later versions, you can hold down the mode switch button for 6s and release it to start the web initial login mode. Either of the following situations will occur:

If the switch has no configuration file, the system attempts to enter the web initial login mode. In this mode, the status of mode indicators is as follows:
- If the system enters the web initial login mode successfully, all mode indicators turn green and stay on for a maximum of 10 minutes.
- If the system fails to enter the initial login mode, all mode indicators fast blink for 10 seconds and then restore to the default status.
If the switch has a configuration file, the system cannot enter the web initial login mode. In this case, all mode indicators fast blink for 10s, and then return to the default states.

Figure 4-26 Indicators on the S5700-28X-LI-AC

Table 4-68 Description of indicators on the switch

Number	Indicator/Button	Color	Description
1	PWR: internal power supply indicator	-	Off: The switch is powered off.
		Green	Steady on: The switch is powered on.
		Yellow	Steady on: The built-in power module is faulty, and the switch is powered by the RPS system.
2	RPS: RPS power supply indicator	-	Off: No RPS is connected to the switch.
		Green	Steady on: The RPS is in cold backup state. Blinking: The RPS is providing power for another device.
		Yellow	Blinking: The RPS is providing power for the switch and the built-in power module of the switch is faulty.
3	SYS: system status indicator	-	Off: The system is not running.
		Green	Fast blinking: The system is starting. The system is copying the system software and configuration file from a USB flash drive during a USB-based upgrade (only applicable to S5701-28X-LI-AC). 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 (only applicable to S5701-28X-LI-AC). NOTE: The system can wake from the sleeping state if you press the MODE button. The S5700-10P-LI-AC does not support the sleeping function.
		Red	Steady on: The system does not work normally after registration, or a fan or temperature alarm has been generated. Blinking: The system cannot be upgraded after a USB flash drive is inserted. The USB-based upgrade failed (only applicable to S5701-28X-LI-AC).
4	STAT: status indicator	Green	Off: The status mode is not selected. Steady on: The status mode (default mode) is selected. If the status mode is selected, the service port indicator shows the port link or activity state.
5	SPED: speed indicator	Green	Off: The speed mode is not selected. Steady on: The speed mode is selected. If the speed mode is selected, the service port indicator shows the port speed state. After 45 seconds, the service port indicators automatically restore to the status mode.
6	STCK: stack indicator NOTE: This indicator has different states and meanings in different versions. Here are the indicator states and meaning in versions earlier than V200R003C00.	Green	Off: The stack mode is not selected. Steady on: The service port indicators show the stack information. After 45 seconds, the service port indicators automatically restore to the status mode. Blinking: The switch is the master switch in a stack or a standalone switch.
	STCK: stack indicator NOTE: This indicator has different states and meanings in different versions. Here are the indicator states and meaning in V200R003C00 and later versions.	Green	If you are not changing the indicator mode (default): Off: The switch is in stack standby or slave state or the stacking function is not enabled on the switch. Blinking: The switch is a stack master switch or a standalone switch with the stacking function enabled.
		Green	If you are changing the indicator mode: Off: The stack mode is not selected. Steady on: The switch is a standby or slave switch in a stack, and the service port indicators show the stack ID of the switch. Blinking: The switch is the master switch in a stack or a standalone switch, and the service port indicators show the stack ID of the master switch. After 45 seconds, the service port indicators automatically restore to the status mode.
7	MODE: mode switch button	-	When you press this button once, the service port indicators change to the speed mode and show the speed of each service port. When you press this button a second time, the service port indicators change to the stack mode and show the stack ID of the local switch. When you press this button a third time, the service port indicators restore to the default mode, and the STAT indicator turns green. If you do not press the MODE button within 45 seconds, the service port indicators restore to the default mode. In this case, the STAT indicator is steady green, the SPED indicator is off, and the STCK indicator is off or blinking green.
8	Service port indicator GE electrical ports: The ports are numbered from bottom to top and left to right, starting with 1. SFP/SFP+ optical ports: Each port has an indicator above it.	Meanings of service port indicators vary in different modes. For details, see Table 4-69.

Stack	-	Off	Port indicators do not show the stack ID of the switch.
	Green	Steady on	The switch is not the master switch in a stack. If the indicator of a port is steady on, the number of this port is the stack ID of the switch. If the indicators of ports 1 to 9 are steady on, the stack ID of the switch is 0.
	Green	Blinking	The switch is the master switch in a stack. If the indicator of a port is blinking, the number of this port is the stack ID of the switch. If the indicators of ports 1 to 9 are blinking, the stack ID of the switch is 0.

Power Supply Configuration

The S5700-28X-LI-AC has a built-in power module and does not support pluggable power modules. It can connect to an RPS1800 power supply for power redundancy.

Figure 4-27 shows the power supply mode of a built-in AC power module. The built-in AC power module (PWR) receives power from an external power source and provides a 12 V output to the chassis.
