Functions

The LX1D2SFUX000 provides the data plane for the entire system. The data plane provides high-speed, non-blocking data channels for data switching between service modules.

The LX1D2SFUX000 consists of the following functional modules:

Switching module: functions as the data plane and provides high-speed service channels for data switching.
Local clock module: provides the working clock for the chips of the switching module, management module, and monitoring module on the LX1D2SFUX000.
Power supply module: provides power supply for the LX1D2SFUX000.

Table 7-44 Functions of the LX1D2SFUX000

Function	Description
Basic function	Core of data switching in the S9310X system.
Clustering	10GE or 40GE optical ports on the card can be used for cluster connection.
Memory	512 MB
Flash	64 MB
Redundancy backup	1+1 hot standby LX1D2SFUX000 cards in a chassis work in redundancy mode to improve system reliability. If one SFU fails, service traffic on this card will be switched to other SFUs to ensure uninterrupted services.
Hot swapping	Supported NOTICE: Before removing a running SFU, hold down the OFL button on the SFU until the OFL indicator turns red.

Usage Constraints

A chassis can have only one type of SFUs installed.

Indicators and Ports

Figure 7-21 Indicators and buttons on the LX1D2SFUX000 panel

Table 7-45 Indicators and buttons on the LX1D2SFUX000 panel

Number	Indicator/Button	Color	Description
1	10GE optical port indicator (LINK/ALM)	Green	Steady on: The link status of the CSS port is Up.
		Red	Steady on: The port is incorrectly connected or an exception occurs on the port.
		-	Off: The link status of the port is Down.
2	40GE optical port indicator (LINK/ALM)	Green	Steady on: The link status of all the internal four CSS ports is Up.
		Yellow	Steady on: The link status of some of the internal four CSS ports is Up, and the link status of others is Down.
		Red	Steady on: The port is incorrectly connected or an exception occurs on the port.
		-	Off: The link status of all the internal four CSS ports is Down.
3	OFL button	-	If there are at least two SFUs installed and running properly, before removing one SFU, hold down the OFL button on the SFU until the OFL indicator blinks red or turns steady red. When the OFL indicator turns steady red indicating that the SFU is isolated from the system, you can remove the SFU. When an SFU is running normally, its RUN/ALM indicator blinks green slowly and its OFL indicator is off.
4	OFL indicator	Red	Steady on: The SFU has been separated from the system and can be removed from the chassis. Blinking: The SFU is being separated from the system and cannot be removed from the chassis. Off: The SFU is running and cannot be removed from the chassis.
5	RUN/ALM: running status indicator	Green	Steady on: The card is powered on. If the indicator is steady green for no more than 30 seconds, the CPU is being started. If the indicator is steady green for more than 30 seconds, the software is not running. Slow blinking: The card software is running properly. Fast blinking: The card software is starting.
		Red	Steady on: The card has failed and the fault requires manual intervention.
		Yellow	Steady on: The card is powered off. (For example, the card has been forcibly powered off using the power off command or is about to start.)

Figure 7-22 Ports on the LX1D2SFUX000 panel

1	Four 10GBASE SFP+ optical ports used for cluster connection between two chassis. They are multiplexed with the 40GE optical port. Either the 10GE ports or 40GE port can work at a time. By default, the four 10GBASE SFP+ optical port are used preferentially.
2	One 40GBASE-X optical port used for cluster connection between two chassis. It is multiplexed with the four 10GE optical ports. Either the 40GE port or 10GE ports can work at a time.

Each LX1D2SFUX000 card has two port groups: group 1 with 10GE ports 1-4 and group 2 with 40GE port 1. Two chassis can set up a cluster only when the following requirements are met:

One SFU can be connected to only one SFU in the other chassis. It cannot be connected to more than one SFU in the other chassis or to an SFU in the local chassis.
Ports in group 1 on one SFU can only be connected to ports in group 1 on the other SFU. In addition, ports in group 1 must be connected sequentially based on their numbers. The port in group 2 on one SFU can only be connected to the port in group 2 on the other SFU.
The two chassis must be connected by at least one cluster cable.

To keep cluster cables neat and facilitate maintenance, you are advised to connect the two chassis according to Figure 7-23 or Figure 7-24:

Connect at least two cables on each SFU.
Install at least two SFUs in each chassis.
