3.1.1  How Do I Calculate the Power Consumption of a CE Series Switch?

CE12800

The power consumption of a CE12800 series switch is the total power consumption of the chassis (including fan modules) and all modules installed in the chassis (MPU x 2 + CMU x 2 + SFU x N + LPU x N). You can use the Hardware Configuration Tool to calculate the power consumption of a switch.

3.1.3  What Requirements Should Cabinets for the CE Series Switches Meet?

CE12800

A standard 19 inch four-post cabinet or rack is recommended for the CE12800 series switches. Use Huawei expandable guide rails to support the chassis in the cabinet/rack. Expandable guide rails for the CE12804/CE12808/CE12812/CE12816 switches are expandable between 700 mm to 900 mm, and expandable guide rails for the CE12804S/CE12808S/CE12804E/CE12808E/CE12816E switches are expandable between 500 mm and 850 mm. If you use third-party guide rails or trays, ensure that they have sufficient load bearing capacity.

A Huawei CE12800 cabinet can accommodate two CE12808 switches. To install two CE12808 switches in the same cabinet, install a switch at the bottom and then install the other on the top. Leave certain space above and below the two switches for cabling.

The power distribution unit (PDU) in a CE12800 cabinet provides both 10 A PDU (C13) and 16 A PDU (C19) sockets. If you want to connect a CE12800 switch and another small-sized device to the PDU simultaneously, properly plan the power cable connections to ensure reliable power supply for the two devices. (Sockets on the PDU are divided into different groups for proper power cable connections.) Ensure that the fault of one device does not affect the other device.

A cabinet for the CE12800 series switches must meet the following requirements:

  • The cabinet/rack must provide reliable ground points for switch grounding. (The ground cable delivered with a switch is 850 mm long.)
  • The cabinet/rack must meet the requirements for front-to-back airflow. The cabinet must meet the requirements for front-to-back airflow, and the front and rear doors must have a porosity rate of more than 50%.
  • If you use AC power cables delivered from Huawei, ensure that an AC power outlet is available within 3000 mm (cable distance) away from the switch.
  • The cabinet must be installed on concrete floor or ESD floor (placed on the floor directly or fixed by expansion bolts). If necessary, use an earthquake-proof cabinet complying with GR63 Zone4 or Zone3 standard.

In addition to the preceding requirements, different models of the CE series have their own requirements for a cabinet/rack, as described in Table 3-3.

CE8800&7800&6800&5800

Table 3-4 describes the requirements of the CE8800&7800&6800&5800 series switches for a cabinet/rack.

Table 3-4  Requirements for the cabinet/rack
ItemRequirement
WidthUse a standard 19 inch four-post cabinet or rack. The CE7800&6800&5800 series switches and CE8850 are 43.6 high. The CE8860 is 88.1 mm high. With their widths in compliance with industry standards, these switches can be installed in a standard 19 inch cabinet/rack.
DepthA separately purchased non-standard cabinet/rack must have sufficient space for chassis installation. The cabinet for a CE5800 or CE6800 (420 mm deep) switch must be no less than 600 mm deep, and the cabinet for a CE6800 (600 mm deep), CE7800, or CE8800 switch must be no less than 800 mm deep.
Heat dissipationThe CE8800&7800&6800&5800 series switches use front-to-back or back-to-front airflow design. The cabinet must meet the requirement of the airflow.
GroundingThe cabinet must have reliable ground points to ground the chassis.
Distance between front and rear mounting railsWhen the CE8800&7800&6800&5800 series switches need to be installed in the same cabinet with a CE12800 switch, keep the distance between the front and rear mounting rails in the range of 700 mm to 800 mm.
Cabling spaceOn a switch, the side with power modules and fan modules is the power supply side, and the side with service ports is the port side. To ensure sufficient cabling space, reserve at least 130 mm of vertical distance from the port side to the interior side of the cabinet door, and at least 70 mm from the power supply side to the interior side of the cabinet door.

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

All management ports of the CE8800&7800&6800&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 CE8800&7800&6800&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.
ab5bd40435c24606badff3f7c65c8d21 NOTE:

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.

3.1.5  What Is the Operating Temperature Range of the CE Series Switches?

The CE series switches can operate normally within an ambient temperature range of 0°C to 40°C (altitude: 0 m to 1800 m).

ab5bd40435c24606badff3f7c65c8d21 NOTE:
  • When the altitude is between 1800 m and 4000 m, the highest operating temperature for the CE12800 series switches reduces by 1°C every time the altitude increases by 220 m.
  • When the altitude is between 1800 m and 5000 m, the highest operating temperature for the CE8800&7800&6800&5800 series switches reduces by 1°C every time the altitude increases by 220 m.
  • The preceding temperature values refer to the ambient temperature, whereas the temperature shown in the display command output is the PCB surface temperature near high-power chips in the chassis. Whether the temperature is normal depends on whether it is within the temperature alarm threshold. Therefore, if the displayed temperature of a switch does not exceed the alarm threshold, the switch is operating under a normal temperature and has no risk of overtemperature.

3.1.6  Do the CE Series Switches Support Overtemperature Protection?

The CE series switches support overtemperature protection. This function is implemented using the following mechanisms:

  1. Card software monitoring:

    Temperature sensors of cards monitor temperature of key chips and report the temperature data to the CMU. The CMU monitors card temperature and fan speeds in corresponding zones. Once the temperature of a card exceeds the fatal temperature threshold and the fan speed in the corresponding zone is abnormal, the monitoring system powers off the card forcibly. When the card temperature restores to the normal range, the monitoring system powers on the card.

  2. Card hardware design:

    Cards of CE series switches have temperature-sensitive hardware components to monitor real-time temperature in high-temperature zones. Once the temperature of a card exceeds the specified threshold, the card hardware shuts down power output so that the card temperature can drop to the normal range.

The CE12800 series switches support both two protection mechanisms, whereas the CE8800&7800&6800&5800 series switches support only the first protection mechanism.

ab5bd40435c24606badff3f7c65c8d21 NOTE:

All temperature alarm thresholds are set by thermal design engineers based on device running status monitoring results, and alarm thresholds of different device models vary slightly. The hardware alarm threshold for a device is higher than its software alarm threshold.

3.1.7  Can the Lower Enclosure Frame of a CE12800 Series Switch Be Removed?

ab5bd40435c24606badff3f7c65c8d21 NOTE:

Removing the lower enclosure frame is not recommended.

If the following conditions occur during installation of a CE12800 series switch, you can remove the lower enclosure frame:

  • If the chassis cannot be moved into the cabinet with the lower enclosure frame on the chassis, remove the lower enclosure frame before placing the chassis into the cabinet.
    ab5bd40435c24606badff3f7c65c8d21 NOTE:

    After 2/3 of the chassis is in the cabinet, install the lower enclosure frame back to the chassis (for installing the air filter door), and then move the chassis completely in the cabinet.

  • If the cabinet is not deep enough for the switch, determine whether the distance between the front mounting rails and the front door meets the switch installation requirement. For details, see 3.1.3 What Requirements Should Cabinets for the CE Series Switches Meet?. If the front door cannot be closed after the switch is installed in the cabinet, remove the lower enclosure frame from the chassis.
    8131b10ce85e4003869823e4f062d6a9 NOTICE:

    If lower enclosure frame is removed because the cabinet depth is small, the chassis header and cable management frames cannot be installed either. Without cable management frames, cables cannot be properly routed. This may affect normal service operations. Therefore, use a qualified cabinet for the CE12800 series switches.

3.1.8  How Do I Power on a CE12800 Series Switch?

First check whether the input voltage for the switch is within the allowed range. If the input voltage is normal, turn on the power switch of the power supply system, and then turn on the power switch on the switch. (A CE12804S switch does not have a power switch.)

ab5bd40435c24606badff3f7c65c8d21 NOTE:

After powering on a switch, check indicators on the switch to determine whether the switch is running normally. For a CE12804/CE12808/CE12812/CE12816 switch, first check the indicators on the chassis header. (The PWR, FAN, SFU, and MPU indicators should be steady green). For a CE12804S/CE12808S/CE12804E/CE12808E/CE12816E switch, first check the indicators on the Main Control Units (MPUs). (The PWR and FAN indicators should be steady green, and the RUN/ALM indicator should be slow blinking green.) If the preceding indicators are in normal status, check indicators on other modules.

Figure 3-8 shows the procedure for powering on a CE12800 switch for the first time.

3.1.11  What Does It Mean When the SYS Indicator on the CE8800&7800&6800&5800 Series Switches Is Steady Red?

On the CE8800&7800&6800&5800 series switches (except the CE6850-48T4Q-EI), the steady red state of the SYS indicator means one of the following:
  • The system fails to start.
  • At least one power module does not work normally.
  • At least one fan module does not work normally.
On the CE6850-48T4Q-EI, the steady red state of the SYS indicator means one of the following:
  • The system fails to start.
  • At least one power module does not work normally.
  • At least one fan module does not work normally.
  • The card power consumption exceeds the rated power of the power modules.

3.1.12  What Optical Modules Does the CE6850-48S4Q-EI Support?

A CE6850-48S4Q-EI switch has 48 10GE SFP+ optical interfaces and 4 40GE QSFP+ optical interfaces. The 10GE SFP+ optical interfaces supports 10GE and GE optical modules as well as GE copper modules (supporting 10/100/1000 Mbit/s transmission rates). The 40GE QSFP+ optical interfaces support 40GE optical modules.

ab5bd40435c24606badff3f7c65c8d21 NOTE:

N+N backupc: If the actual chassis power consumption exceeds the maximum output power provided by power modules in the N+N backup mode, this backup mode cannot be used. The N+1 backup mode is recommended in this case.

If the AC power modules use a 110 V power source, follow these suggestions:

  1. Use double live wires. In this case, the output power of a power module is 2700 W/3000 W.
  2. If only one live wire is used, the output power of a power module is 1200 W/1500 W. In this case, it is recommended that you use more power modules or change the power module backup mode to increase the output power.
