Port Description

10/100/1000BASE-T port
A 10/100/1000BASE-T Ethernet electrical port sends and receives service data at 10/100/1000 Mbit/s, and must use an Ethernet cable. Table 4-131 describes the attributes of a 10/100/1000BASE-T Ethernet electrical port.

1000BASE-X port
When a 1000BASE-X port uses a GE optical module, it can only transmit and receive data at 1000 Mbit/s and does not support the 100 Mbit/s transmission speed. When a 1000BASE-X port uses a GE copper module, it can transmit and receive data at 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s. Table 4-132 describes the attributes of a 1000BASE-X Ethernet optical port.

Console port
The console port is connected to a console for on-site configuration. The port must use a console cable. The console port is used when a switch is powered on for the first time. For details about the attributes of a console port, see Table 4-133.

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

NOTE:
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.

Description

1

PWR: built-in power module 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

SYS: system status indicator

-

Off: The system is not running.

Green

  • Fast blinking: The system is starting.
  • Slow blinking: The system is operating properly.

Yellow

Blinking: The system is in the sleep state.

NOTE:
The system can wake from the sleeping state if you press the MODE button.

Red

Steady on: The system does not work normally after registration, or a fan or temperature alarm has been generated.

3

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.
4

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.

5

STCK: stack indicator

-

Currently, the switch does not support stacking. This indicator is reserved for the stacking function.

6

MODE: mode switch button

-

  • When you press this button once, the SPED indicator turns green and the service port indicators show the speed of each service port.
  • When you press the button a second time, the STAT indicator turns green.

If you do not press the button within 45 seconds, the indicators restore to the default states. That is, the STAT indicator turns green, and the SPED and STCK indicators are off.

7

Service port indicator

  • GE electrical ports: The ports are numbered from bottom to top and left to right, starting with 1.
  • GE optical ports: Each port has an indicator above it.

Meanings of service port indicators vary in different modes. For details, see Table 4-135.

8

Mini USB indicator

Green

  • Off: The Mini USB port is not active, and the console port is active.

  • Steady on: The Mini USB port is active.

When this indicator is on, the console indicator is off.

9

Console indicator

Green

  • Off: The console port is not active, and the Mini USB port is active.

  • Steady on (default): The console port is active.

When this LED is on, the Mini USB port indicator is off.

Power Supply Configuration

The S5700S-28P-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 4-53 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.

L: live wire

N: neutral wire

PGND: protection ground

GND: 12 V reference ground

Heat Dissipation

The S5700S-28P-LI-AC has no fans and uses natural heat dissipation.
