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/


22/208



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.

The OOS indicator can be either red or amber. The

indicator is amber in European mode and is red in

North American mode.

If you want to set the OOS indicator color based on

region, run SET OOSCOLOR.

Off: The board is operating normally, and

the services are running normally.

On or blinking: The board is out of

service.

The OOS indicator blinks ten times during

the power-on of the board.

When the OOS indicator is blinking, the possible

causes are as follows:

The board is not powered on.

The board is powered on, but a fault

occurs.

The board is being reset.

HEALTHY Red orgreen

Health indicator This indicator can be displayed in green or red,which depends on the operating status of the board.

Off: No power is supplied to the board.

Steady green: No alarm is generated for

the board.

Steady red: The board is faulty.

Blinking red: An alarm is generated for

the board.

The alarm severity varies depending on the HEALTHY

indicator blinking frequency:

If the indicator blinks at a frequency of

0.5 Hz, a minor alarm is generated.


1 Hz, a major alarm is generated.


4 Hz, a critical alarm is generated.

SYSTEM Red or

yellow

Customized

indicator

You can customize the function of this indicator.


38/208



HOTSWAP Blue Hot-swap indicator Off: The board is activated.

Steady on: The board is deactivated or

not powered on.

Blinking at long intervals (on for 900 ms

and then off for 100 ms alternately): The

board is requesting activation. (The

indicator turns off after activation.)

Blinking at short intervals (on for 100

ms and then off for 900 ms alternately):

The board is requesting deactivation.

(The indicator becomes steady on after

deactivation.)

NOTE:

You can remove the board only when the HOTSWAP

indicator is steady on.

HD_ACT

indicator

Green Hard disk status

indicator

The HD_ACT indicator indicates whether the hard

disk is activated or is reading or writing data.

Off: The hard disk is not installed or is

deactivated.

On: The hard disk is activated.

Blinking irregularly: The hard disk is

reading or writing data.

HD_RAID/ALM

indicator

Red or

yellow

Hard disk status

indicator

The HD_RAID/ALM indicator indicates that the hard

disk is in RAID synchronization state or a fault

occurs.

Off: RAID synchronization is complete,

and the hard disk is operating properly.

Blinking yellow: The hard disk is in RAID

synchronization state.

Steady red: The hard disk is lost or

faulty.

Logical Structure

The board provides five interfaces named Update, Base1, Base2, Fabric1, and Fabric2. Figure 3

shows the positions of the five interfaces on the board.

Figure 3 Interfaces on the board


40/208



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.

When you raise both the ejector levers simultaneously, the board is powered off.

NOTE:

If you power on the board by lowering one ejector lever, a minor alarm is generated to prompt you

to lower the other ejector lever.

Interfaces

The front panel of the board provides two USB interfaces and a COM serial port, which are

described in Table 3.

Table 3 Interfaces on the board

Interface Name Description

USB interface This interface is used to connect to USB devices, such as mouse and keyboard.

It also serves as a KVM interface to connect to the KVMS if the UPB is not

configured with a back board.

COM serial port This port is used as a BMC serial port (to connect to the CPU of a management

module) or a system serial port (to connect to the CPU of a service module).

By default, it is used as a BMC serial port.

Indicators

The front panel of the UPB provides five indicators, namely, OOS, HEALTHY, SYSTEM, HOTSWAP, and

HD. The indicators indicate the operating status of the UPB. Table 4describes these indicators.

Table 4 Indicators on the board

Indicator Color Meaning Description

OOS Red or

amber

Service status

indicator

The OOS indicator can be either red or amber. The

indicator is amber in European mode and is red in

North American mode.

If you want to set the OOS indicator color based on

region, run SET OOSCOLOR.

Off: The board is operating normally, and

the services are running normally.

On or blinking: The board is out of

service.

The OOS indicator blinks ten times during

the power-on of the board.

When the OOS indicator is blinking, the possible

causes are as follows:

The board is not powered on.

The board is powered on, but a fault

occurs.

The board is being reset.

HEALTHY Red orgreen

Health indicator This indicator can be displayed in green or red,which depends on the operating status of the board.

Off: No power is supplied to the board.

Steady green: No alarm is generated for

the board.

Steady red: The board is faulty.

Blinking red: An alarm is generated for

the board.

The alarm severity varies depending on the HEALTHY

indicator blinking frequency:


0.5 Hz, a minor alarm is generated.


1 Hz, a major alarm is generated.


4 Hz, a critical alarm is generated.

SYSTEM Red or

yellow

Customized

indicator

You can customize the function of this indicator.


47/208



HOTSWAP Blue Hot-swap indicator Off: The board is activated.

Steady on: The board is deactivated or

not powered on.

Blinking at long intervals (on for 900 ms

and then off for 100 ms alternately): The

board is requesting activation. (The

indicator turns off after activation.)

Blinking at short intervals (on for 100

ms and then off for 900 ms alternately):

The board is requesting deactivation.

(The indicator becomes steady on after

deactivation.)

NOTE:

You can remove the board only when the HOTSWAP

indicator is steady on.

HD_ACT

indicator

Green Hard disk status

indicator

The HD_ACT indicator indicates whether the hard

disk is activated or is reading or writing data.

Off: The hard disk is not installed or is

deactivated.

On: The hard disk is activated.

Blinking irregularly: The hard disk is

reading or writing data.

HD_RAID/ALM

indicator

Red or

yellow

Hard disk status

indicator

The HD_RAID/ALM indicator indicates that the hard

disk is in RAID synchronization state or a fault

occurs.

Off: RAID synchronization is complete,

and the hard disk is operating properly.

Blinking yellow: The hard disk is in RAID

synchronization state.

Steady red: The hard disk is lost or

faulty.

Logical Structure

The board provides five interfaces named Update, Base1, Base2, Fabric1, and Fabric2. Figure 3

shows the positions of the five interfaces on the board.

Figure 3 Interfaces on the board


49/208



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.
