Port Description

10GE SFP+ port

A 10GE SFP+ Ethernet optical port supports auto-sensing to 1000 Mbit/s. It sends and receives service data at 1000 Mbit/s or 10 Gbit/s. Table 5-5 describes the attributes of a 10GE SFP+ 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 5-6.

ETH management port

You can connect a switch to a configuration terminal or network management workstation through the ETH management port to configure the switch locally or remotely. The port must use an Ethernet cable. You can choose to download the software package through the ETH management port in the BootROM menu. File transfer through the ETH management port is faster than transfer through the console port. For details on how to use the ETH management port, see the Configuration Guide - Basic Configurations.

USB port

The USB port can have a USB flash drive connected to upgrade the switch, or transfer configuration files or other files. The USB port can only connect to a USB flash drive that complies with USB 2.0.

USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.

  • 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

  • Steady on: The system is performing self-check during startup (only applicable to V100R006).

  • Blinking: The system has been successfully upgraded using a USB flash drive and the switch has restarted. You can remove the USB flash drive from the switch.

Red

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

  • Blinking: An error occurred during USB-based upgrade and the system failed to be upgraded after a USB flash drive is inserted.

4

MODE: mode indicator

-

Off: The service port indicators are in the status mode (default). In the status mode, the service port indicator shows the port link or activity state.

Green

Steady on: The service port indicators show the port speed. After 45 seconds, the service port indicators automatically restore to the status mode.

Red

Steady on: The service port indicators show the stack ID of the switch. After 45 seconds, the service port indicators automatically restore to the status mode.

5

Mode switch button

-

  • When you press this button once, the mode indicator turns green and the service port indicators show the speed of each service port.
  • When you press this button a second time, the mode indicator turns red and the service port indicators show the stack status.
  • When you press this button a third time, the mode indicator turns off.

If you do not press the button within 45 seconds, the mode indicator restores to status mode.

    • If the first nine port indicators of the switch are steady on, the stack ID of the switch is 0.

  • If both indicators are blinking, the switch is a master switch:

    • If the indicator of a port is blinking, the number of this port is the stack ID of the switch.

    • If the first nine port indicators of the switch are blinking, the stack ID of the switch is 0.

Power Supply Configuration

The S6700-24-EI can use a single power module or double power modules for 1+1 power redundancy. In versions prior to V200R005C00, the switch cannot use AC and DC power modules simultaneously. In V200R005C00 and later versions, the switch support mixing of AC and DC power modules.

Figure 5-5 shows the power supply connections of dual DC power modules. After DC power is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the motherboard provides power for the entire device.
Figure 5-5 Power supply connections of dual DC power modules

NEG: Negative wire

RTN: Positive wire

GND: -53 V reference ground

Figure 5-6 shows the power supply connections of dual AC power modules. After AC power is transmitted to the PWR module, the PWR module provides -53 V output voltage, and the motherboard provides power for the entire device.

L: Live wire

N: Neutral wire

PGND: Protection ground wire

GND: -53 V reference ground

Heat Dissipation

The S6700-24-EI uses pluggable fan modules for forced air cooling. Air flows in from the left and right sides, and exhausts from the rear panel.
