Air filter

The air filters of the NIP6860 are deployed on the air intake vents of chassis air channels to protect the device against dust.

2

SRU

The Switch Router Unit (SRU) on the NIP6860 is in charge of system control and route information learning. It is the central control unit of the device. The NIP6860 SRUs work in 1:1 backup mode. When the active SRU is faulty, the standby SRU immediately takes over for it, ensuring service continuity.

The NIP6860 SRU is integrated with an SFU for data switching.

3

SFU

The SFUs of the NIP6860 are responsible for the data switching of the entire system. The NIP6860 has one separate SFU. It works with the SFUs integrated in the two SRUs in 2+1 backup mode for load balancing.

Fan module

The NIP6860 has two fan modules. They are deployed on the air intake vents of chassis air channels and work in 1+1 backup mode.

2

ESD jack

The equipment end of the wrist strap is inserted into the ESD jack. For the wrist strap to be effective, ensure that the device is grounded.

3

Protection ground terminal

The OT terminal of the ground cable is connected to the protection ground terminal of the device, and the other terminal of the ground cable is connected to the ground point of the cabinet or workbench or the ground bar of the equipment room.

4

Rear cable rack

Used for laying optical fibers and cables. There are two rear cable racks on the upper parts of the power modules.

5

Power supply areas

Power supply areas of the four PEMs on the NIP6860.

6

PEM module

The NIP6860 uses four PEMs for DC power supply. The NIP6860 backplane is divided into two areas, each of which has two PEM power inputs. These eight power inputs work in 2+2 backup mode.

If the NIP6860 uses the AC power supply, one additional external AC power chassis is required.

Slots Layout

Figure 1-7 shows the slot layout on the NIP6860.

Power Supply System

The NIP6860 supports either DC and AC power supplies (but not at the same time).

  • If DC power supply is used, the DC power cables are directly connected to the input terminals of the PEMB DC power module.

  • If AC power supply is used, an external EPS200-4850A AC power chassis is employed. The number of rectifier modules depends on the system power consumption. The AC power enclosure is connected to the PEM input to provide power for the device. That is, AC power supply uses external AC power enclosures on the basis of DC power supply.

As shown in Figure 1-8, the NIP6860 backplane is divided into two areas, each with two power inputs. These four power inputs work in backup mode.

Figure 1-8  Distributed architecture of the NIP6860 power supply

DC power supply system

The NIP6860 uses four 70 A PEM modules that work in 2+2 backup mode for DC power supply. Table 1-7 describes the power supply solution.

AC power supply system

Table 1-7 shows the power supply architecture of the NIP6860 AC power supply system. The input AC power is output as steady DC power after being converted by the AC/DC module and being transmitted along external cables to the PEM to power all boards and fans.

Heat Dissipation System

The NIP6860 provides a dedicated fan module and a dedicated air filter and uses a unique airflow design for heat dissipation.

  • The NIP6860 has altogether two fan modules located at the air exhaust for 1+1 backup. The two fan modules are deployed side by side, and each fan module has one fan. When one fan fails, the system can still work at the ambient temperature of 40°C for a short period of time. For details on the fan module, see CR52FCBH Fan Module.
  • The NIP6860 has one air filter fixed at the air intake vent of the chassis with a cable-retention clip. The air filter prevents dust from entering the chassis with airflow. In addition, the air filter has a curved face with holes all around, large area, and small windage resistance, improving the heat dissipation efficiency. For details on the air filter, see Air Filter (NIP6860).
  • The NIP6860 system draws air from the front and discharges air from the back. The air intake vent is above the front board slot area, and the air exhaust locates at the fan module.

Figure 1-11 shows the air flow in the NIP6860.
