Blinking red An alarm is generatedfor the fan tray.
Hardware Structure
The structure of the T8280 subrack is described as follows:
The fan tray adopts the split design and consists of two layers. That is, each subrack
is configured with two fan trays. With this design, the failure in one fan tray does
not affect the heat dissipation of the entire subrack.
http://void%280%29/http://void%280%29/http://void%280%29/http://void%280%29/http://void%280%29/http://void%280%29/http://void%280%29/http://void%280%29/8/9/2019 HSS Hardware Architecture

The fan tray is located under the board slots. It consists of the frame, fan monitoring
board, and fans. It supports online maintenance and hot swapping.
The fan tray contains 6 fans [The size of each fan (H x W x D): 120 mm x 120 mm x 25.4
mm (4.72 in. x 4.72 in. x 1.00 in.)], which are arranged in three columns, each with
two fans. The fans are secured in the fan tray with screws.
Adopting the bottom-to-top ventilation mode, the fan tray draws air in from the intake
panels in the front and on both sides and exhausts air out through the upper and lower
air exhaust vents at the rear of the subrack.The fans in the fan tray support N+1 redundancy. Thus, the failure of a fan does not
affect the operation of the entire subrack.
The fan tray is equipped with a fan monitoring board, which automatically controls the
rotation speed of the fans and generates an alarm if a fan fails.
The fan trays cool the components in the subrack. Figure 2shows the direction of air flow in the
subrack.

In Figure 3, Base1 and Base2 are network interfaces of the Base plane; Fabric1 and Fabric2 are
network interfaces of the Fabric plane; the Update interface is used for the interconnection
between two UPBs.
The functions of the interfaces are as follows:
The Base plane is used for exchanging management and maintenance information such as
software loading and alarms. The Base interfaces (Base1 and Base2) on all UPBs are
connected to the Base interfaces on the SWUs in slots 6 and 7 through the backplane.
Thus, the UPBs in different slots can exchange data through the SWUs. Base1 of a UPB
exchanges data with Base1 of another UPB, and Base2 of a UPB exchanges data with Base2
of another UPB.
The Fabric plane is used for exchanging service data. The Fabric interfaces (Fabric1
and Fabric2) on all UPBs are connected to the Fabric interfaces on the SWUs in slots 6
and 7 through the backplane. Thus, the UPBs in different slots can exchange service
data through the SWUs. Fabric1 of a UPB exchanges data with Fabric1 of another UPB, andFabric2 of a UPB exchanges data with Fabric2 of another UPB.
The Update interface is used by a pair of active and standby UPBs to exchange data. The
Update interface of one UPB is connected to the Update interface of the mated UPB in
point-to-point mode through the backplane. Table 6lists the one-to-one relations
between the UPBs. The data exchanged between the Update interfaces is transmitted
through the backplane, instead of the SWUs.

In Figure 3, Base1 and Base2 are network interfaces of the Base plane; Fabric1 and Fabric2 are
network interfaces of the Fabric plane; the Update interface is used for the interconnection
between two UPBs.
The functions of the interfaces are as follows:
The Base plane is used for exchanging management and maintenance information such as
software loading and alarms. The Base interfaces (Base1 and Base2) on all UPBs are
connected to the Base interfaces on the SWUs in slots 6 and 7 through the backplane.
Thus, the UPBs in different slots can exchange data through the SWUs. Base1 of a UPB
exchanges data with Base1 of another UPB, and Base2 of a UPB exchanges data with Base2
of another UPB.
The Fabric plane is used for exchanging service data. The Fabric interfaces (Fabric1
and Fabric2) on all UPBs are connected to the Fabric interfaces on the SWUs in slots 6
and 7 through the backplane. Thus, the UPBs in different slots can exchange service
data through the SWUs. Fabric1 of a UPB exchanges data with Fabric1 of another UPB, andFabric2 of a UPB exchanges data with Fabric2 of another UPB.
The Update interface is used by a pair of active and standby UPBs to exchange data. The
Update interface of one UPB is connected to the Update interface of the mated UPB in
point-to-point mode through the backplane. Table 6lists the one-to-one relations
between the UPBs. The data exchanged between the Update interfaces is transmitted
through the backplane, instead of the SWUs.
