Power Supply Slot Configuration

NOTE:

2200 W AC, 2200 W DC, 3000 W AC modules can be used together in a switch.

The S12710 supports both AC and DC power modules and provides slots PWR1 to PWR4 for power modules, as shown in Slot layout on the S12710 chassis (front).

The S12710 supports three redundancy modes of power modules: N+N, N+1, and N+0 (no redundancy). The value of N depends on the power consumption of the system. Ensure that the total maximum output power of N power modules (N x maximum output power of each power module) is larger than the power consumption of the system. For example, the maximum power required by the system is 4000 W. If two 2200 W power modules are installed in the chassis, they work in 2+0 mode. If three 2200 W power modules are installed, they work in 2+1 redundancy mode. If four 2200 W power modules are installed, they work in 2+2 redundancy mode. The system can identify the power redundancy mode, and you do not need to manually configure the power redundancy mode. Table 4-18 describes the three power redundancy modes supported by the S12710.

Table 4-18  Description of power redundancy modes

Redundancy Mode

Description

Product Support

N+N
  • System power supply is not affected if no more than N power modules are removed or fail.
  • The maximum output power of the system is the total maximum output power of N power modules.
  • The first N represents mandatory power modules, and the second N represents optional power modules.
NOTE:

The N+N redundancy mode is often used when two power supply systems are available. In this case, the first N represents mandatory power modules for the first power supply system, and the second N represents mandatory power modules for the second power supply system. The use of double power supply systems provides redundancy for both power modules and power supply systems.

1+1, and 2+2 redundancy

N+1
  • System power supply is not affected if one power module is removed or fails.
  • The maximum output power of the system is the total maximum output power of N power modules.
  • N power modules are mandatory, and one power module is optional.

1+1, 2+1, and 3+1 redundancy

N+0 (no redundancy)
  • System power supply is affected once any power module is removed or fails.
  • The maximum output power of the system is the total maximum output power of N power modules.
  • N power modules are mandatory, and there are no optional power modules.

1+0, 2+0, 3+0, and 4+0

NOTE:
  • When using the N+N redundancy mode, equally divide the power modules into two groups and connect the two groups of power modules to two independent power supply systems. This configuration provides redundancy of power supply systems to enhance system reliability.

  • When using the N+N redundancy mode, you are advised to install N power modules (as specified by the first N) in the power supply slots at the left side and install N power modules (as specified by the second N) in the power supply slots at the right side. Power slots are marked PWR.

  • If the system power consumption exceeds 50% of a single power module's power, all power modules equally share the power consumption. This reduces the load of a single power module and improves the system reliability.

The following describes the power module configuration for an S12710 switch with different power supplies:

DC power input

Table 4-19 describes the power module configuration for the S12710 series switches when DC power input is provided.

Table 4-19  Power module configuration (DC power input)
Power Module Type Redundancy Mode Maximum Output Power

N+0 (no redundancy)

A maximum of 4 (4+0) 2200 W DC power modules can be configured, providing a maximum output power of 8800 W.

AC power input (220 V single-phase or 110 V dual-live-wire input)

NOTE:

If the input voltage is 110 V, the dual-live-wire input mode is recommended. In this case, the maximum output power of a 2200 W AC power module is 2200 W, the maximum output power of a 3000 W AC power module is 3000 W, and the maximum output power of an 800 W AC power module is 800 W.

Table 4-20 describes the power module configuration for the S12710 series switches when 220 V single-phase or 110 V dual-live-wire AC power input is provided.

Heat Dissipation

NOTE:

It is recommended that you replace the air filter of a device every six months.

Fan modules of an S12710 switch are located at the rear of the chassis, and its air filter is located at the left side.

  • The S12710 has four fan modules respectively, located at the rear of the chassis. The fan modules absorb cold air into the chassis to dissipate heat generated by working components, ensuring that the chassis operates within a normal temperature range. For details about the performance and attributes of a fan module, see Fan Module.
  • The air filter prevents dust from entering the chassis with the airflow.

The S12710 chassis are divided into multiple zones. If there are empty slots in a zone, the fans corresponding to that zone operate at a low speed, which reduces power consumption and noise.

As shown in Figure 4-27, an S12710 switch has four fan modules, and each fan module cools four cards in its zone. Cards in slots 4 and 7 are cooled by two adjacent fan modules.

Figure 4-27  S12710 fan zones

Airflow

The S12710 chassis uses a left-to-back airflow design. Cold air is drawn into the chassis from the left side, dissipates heat in the chassis, and is exhausted from the rear of the chassis. Figure 4-28 shows the airflow in the chassis.

NOTE:

The S12704, S12708, S12712, and S12710 chassis have the same airflow design. The S12708 chassis is used as an example here.

Figure 4-28  Airflow in the chassis

Air Filter

NOTE:

The switches may use honeycomb air filters or non-honeycomb air filters. The switches with honeycomb air filters installed in all air filter slots comply with Federal Communications Commission (FCC) standards.

An S12710 switch requires two S12710 air filters.

Figure 4-29 shows a non-honeycomb air filter for the S12710.
