Where Is the Management Port of a CE Series Switch Located? How Is the Management Port Connected?

CloudEngine 12800 and 12800E

The CloudEngine 12800 and 12800E series switches have ETH (RJ45), Console (RJ45), and Mini USB/Micro USB management ports, all of which are located at the front of an MPU.

CE-MPUA-S, CE-MPUB-S, and CEMPUA have the same management ports on the front panel. Figure 22-2 shows the management ports on the CE-MPUA as an example.

Figure 22-2 Management ports on the CE-MPUA

CE-MPUC-S, CE-MPUA-E and CE-MPUB have the same management ports on the front panel. Figure 22-3 shows the management ports on the CE-MPUB as an example.

ETH management port (RJ45)

The ETH management port can be connected to a network management workstation for device management.

Attribute

Description

Connector type

RJ45

Working mode

10M/100M/1000M auto-sensing, half-duplex and full-duplex supported

Standards compliance

IEEE802.3ab

Maximum transmission distance

100 m

Applicable cable

  • When the ETH management port is working in 10M/100M mode, a Category 5 cable is recommended.
  • When the ETH management port is working in 1000M mode, a Category 5 or Category 5e cable is recommended.

Console management port (RJ45)

  • The console port and Mini USB/Micro USB port are multiplexed and share one internal serial port. You can use the console port or Mini USB/Micro USB port as the serial port according to your needs. When the Mini USB/Micro USB is activated, the console port cannot be used.
  • When both the console port and Mini USB/Micro USB port have a cable connected, the Mini USB/Micro USB port is used.

The console port can be connected to a configuration terminal for onsite system configuration.

Attribute

Description

Connector type

RJ45

Working mode

Full-duplex universal asynchronous receiver/transmitter (UART)

Electrical characteristics

RS232

Baud rate

9600 bit/s (default value), which can be changed as required

Applicable cable

8-core shielded cable

Mini USB/Micro USB management port

The Mini USB/Micro USB management port can be connected to a configuration terminal for onsite system configuration, but the configuration terminal must have a USB serial port driver installed. The Mini USB/Micro USB port is used as the serial port once a link is established on the port.

CloudEngine 8800, 7800, 6800, and 5800

The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI, CE6875EI, CE8850-64CQ-EI, CE8860EI, CE8861EI, and CE8868EI) have ETH (RJ45) and console (RJ45) management ports.

Figure 22-4 shows the management ports on the CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI, CE6875EI, CE8850-64CQ-EI, CE8860EI, CE8861EI, and CE8868EI).

Figure 22-4 Management ports on the CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI, CE6875EI, CE8850-64CQ-EI, CE8860EI, CE8861EI, and CE8868EI)

The CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI, and CE6875EI have ETH (combo), console (RJ45), and Mini USB management ports. The console (RJ45) and Mini USB management ports are multiplexed.

Figure 22-5 shows the management ports on the CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI, and CE6875EI.

Figure 22-5 Management ports on the CE6850HI, CE6855-48T6Q-HI, CE6856-48T6Q-HI, CE6850U-HI, and CE6875EI

The CE8850-64CQ-EI, CE8860EI, CE8861EI, and CE8868EI have ETH (combo), console (RJ45), and Mini USB management ports. The console (RJ45) and Mini USB management ports are multiplexed.

Figure 22-6 shows the management ports on the CE8850-64CQ-EI, CE8860EI, CE8861EI, and CE8868EI.

Figure 22-6 Management ports on the CE8850-64CQ-EI, CE8860EI, CE8861EI, and CE8868EI

All management ports of the CloudEngine 8800, 7800, 6800, and 5800 series switches are located at the front of the chassis (power supply side).

ETH (combo), console (RJ45), and Mini USB management ports of the CloudEngine 8800, 7800, 6800, and 5800 series switches have the same attributes as those management ports on the CE12800 series switches.

ETH management port (Combo)

The ETH management port (combo) consists of an electrical port and an optical port. You can connect the electrical or optical port to a configuration terminal or network management workstation to set up the onsite or remote configuration environment. The electrical and optical ports are multiplexed, and only one of them can work at a time.

  • The electrical port uses a Category-5 or higher category network cable.
  • The optical port uses a 100M or GE optical module and matching fibers. A 100M optical module can be used only after the switch starts successfully.

The combo port automatically selects the working mode as follows:

  • If the optical port has no optical module installed and the electrical port has no network cable connected, the port type depends on which port is connected first. If the electrical port is connected by a network cable first, the electrical port is used for data switching. If the optical port has an optical module installed first, the optical port is used for data switching.
  • If the electrical port has a network cable connected and is in Up state, the electrical port is still used for data switching when the optical port has an optical module installed.
  • If the optical port has an optical module installed and is in Up state, the optical port is still used for data switching when the electrical port has a network cable connected.
  • If the optical port has an optical module and fiber installed and the electrical port has a network cable connected, the optical port is used for data switching after the switch restarts.
