Slot

  • Power supply slot

    The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI) have two power supply slots, in which power modules can be installed to provide power to the chassis. A chassis can have one or two power modules. Double power modules can provide higher reliability.

    The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI) support double power modules (1+1 backup).

    • When both power modules are working properly, they equally provide power for a chassis.
    • When one power module fails, the other one provides all power required for a chassis.

    All power modules are hot swappable.

  • Fan slot

    The CloudEngine 8800, 7800, 6800, and 5800 series switches (except the CE8850-64CQ-EI, CE6863-48S6CQ, CE6881-48S6CQ, CE6820-48S6CQ, CE6863-48S6CQ-K, CE6881-48S6CQ-K, CE6881E-48S6CQ and CE6857-48S6CQ-EI) have two fan slots, in which fan modules can be installed to cool the chassis, ensuring efficient heat dissipation and system stability. A chassis must have two working fan modules to ensure normal operating.

    All fan modules are hot swappable.

Airflow

The cooling systems of the CloudEngine 8800, 7800, 6800, and 5800 series switches have front-to-back or back-to-front airflow depending on the airflow direction of the power modules and fan modules used. The airflow direction of the power modules and fan modules required on the CloudEngine 8800, 7800, 6800, and 5800 series switches depends on how the switches are installed in cabinets. Typically, cabinets in a data center have cold air flowing in from the front and hot air exhausted from the back. If CloudEngine 8800, 7800, 6800, and 5800 series switches are installed with the power supply side facing the front, you are advised to use fan modules and power modules with front-to-back airflow in the switches.

  • Front-to-back airflow: The power modules and fan modules using front-to-back airflow are marked download?uuid=08a4d991512d45e99e5a6519ab183fc2 or download?uuid=882b433269ec460f9089504ec6a91f78. Air flows into the chassis from the power supply side and flows out from the port side, as shown in Figure 2-94 (CE5800 as an example).
  • Back-to-front airflow: The power modules and fan modules using back-to-front airflow are marked download?uuid=1cde3e79be6b4e2cae599e517cdd2242 or download?uuid=a919fa8f0cd94a36b8c3ce54cc66fab0. Air flows into the chassis from the port side and flows out from the power supply side, as shown in Figure 2-95 (CE5800 as an example).

  • When the power module and fan module use forcible heat dissipation, they must use the same airflow method. For example, if the power module with back-to-front airflow is used, the fan module with back-to-front airflow must be used.

Fast blinking The system is starting.
Slow blinking The system is running normally.
Red Steady on
  • The system fails to start.
  • At least one power module does not work normally.
  • At least one fan module does not work normally.
2 MST: Stack master/slave indicator

NOTE:

In V200R003C00 and later versions, you can use the dfs-master led enable command to enable the stack master/slave indicator to display the DFS group master and backup status.

After the stack master/slave indicator is enabled to display the DFS group master and backup status, the stack master/slave indicator on the DFS master device is steady on and that on the DFS backup device is off.

 Green Off The switch is not a stack master.
Steady on The switch is a stack master or standalone switch.
3 ID ID indicator Blue Off The ID indicator is not used (default state).
Steady on The indicator identifies the switch to maintain. The ID indicator can be turned on or off remotely to help field engineers find the switch to maintain.
4 – Service port indicator (10GE/25GE optical port)

NOTE:

Each 10GE/25GE optical port has two single-color indicators. The one on the left is the ACT indicator (yellow), and the one on the right is the LINK indicator (green).

Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top.

 Green Off No link has been established on the port or the port has been shut down.
Steady on A link is established on the port.
Yellow Off The port is not sending or receiving data.
Blinking The port is sending or receiving data.
5 – Service port indicator (40GE/100GE optical port)

NOTE:

Arrowheads show the positions of ports. A down arrowhead indicates a port at the bottom, and an up arrowhead indicates a port at the top.

 Green Off No link has been established on the port or the port has been shut down.
Steady on A link is established on the port.
Blinking The port is sending or receiving data.
When a 40GE/100GE port is configured as four 10GE ports or four 25GE ports, this indicator shows the status of a 10GE/25GE port. The sequence number of the indicated port is identified by indicators 40G/100G Breakout 1/2/3/4 on the lower right corner of the panel.

NOTE:

Each 40GE/100GE port has a single-color indicator, which shows the status of the 40GE/100GE port by default.
6 – 40G/100G Breakout 1/2/3/4 (sequence number indicators of 10GE/25GE ports converted from a 40GE/100GE port)

NOTE:

Indicators 1, 2, 3, 4 turn on in cyclic order, with each indicator keeping on for 5s.

 Green Off 40GE/100GE ports are working in 40GE or 100GE mode and not split into four 10GE ports or four 25GE ports.
Steady on At least one 40GE/100GE port has been split into four 10GE ports or four 25GE ports.

When one or more 40GE/100GE ports are split into four 10GE ports or four 25GE ports, these indicators identify the sequence numbers of the 10GE/25GE ports. A port indicator (6 in Figure 2-96) shows the status of a 10GE/25GE port converted from the corresponding 40GE/100GE port:

  • When indicator 1 is on, each port indicator shows the status of the first 10GE/25GE port derived from the corresponding 40GE/100GE port.
  • When indicator 2 is on, each port indicator shows the status of the second 10GE/25GE port derived from the corresponding 40GE/100GE port.
  • When indicator 3 is on, each port indicator shows the status of the third 10GE/25GE port derived from the corresponding 40GE/100GE port.
  • When indicator 4 is on, each port indicator shows the status of the fourth 10GE/25GE port derived from the corresponding 40GE/100GE port.
7 ACT USB-based deployment indicator Green Off USB-based deployment is disabled (default state).

Port use constraints

The 48 10GE/25GE SFP28 optical ports of a CE6860 switch work at the rate of 25 Gbit/s by default and do not support GE/10GE auto-sensing. You can set the port rate to 10 Gbit/s or 1 Gbit/s using the port mode 10g or port mode ge command, respectively. If GE mediums are installed on the first eight 25GE interfaces, you need to run the port mode ge command to configure the interfaces to work at the rate of 1 Gbit/s; if GE mediums are installed on the later 40 25GE interfaces, the port mode 10g command needs to be run, the interfaces automatically work at the rate of 1 Gbit/s, and the port mode ge command does not need to be run.

The 48 10GE/25GE SFP28 optical ports are divided into 12 port groups, with four ports in each group (1-4, 5-8, 9-12…45-48).

  • If the rate of any port in a port group is set to 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s, all the other ports in this group also work at the rate of 1 Gbit/s, 10 Gbit/s, or 25 Gbit/s.

  • When the ports in a port group work at the rate of 25 Gbit/s, they support only 25GE modules or cables and will go Down if other types of modules or cables are used. When the ports in a port group work at the rate of 10 Gbit/s, they support only 10GE or 25GE variable-rate modules or cables and will go Down if other types of modules or cables are used. When the ports in a port group work at the rate of 1 Gbit/s, they support only GE modules or cables and will go Down if other types of modules or cables are used.

  • If the switch is running a version earlier than V200R002C50, the ports in a port group must use the same type of transmission medium (copper or fiber). This constraint does not apply to V200R002C50 and later versions.
