CEL36LQFD1-G (36-port 40GE interface card (FD1-G, QSFP+))

Port status indicator

One single-color indicator for each port

The indicator with an up arrowhead shows the status of the port on the top, and the indicator with a down arrowhead shows the status of the port at the bottom.

When one or more 40GE or 100GE ports are split, these sequence number indicators take effect. The sequence number indicators work with the port indicators to show the status of converted ports.

• If a port is split: When the sequence number indicator N (N can be 1, 2, 3, or 4) is on, the port indicator shows the status of the Nth 10GE or 25GE converted port. Sequence number indicators 1, 2, 3, 4 turn on in cyclic order, with each indicator keeping on for 5s. This is the default automatic mode. You can also press the 40/100GE Breakout button to manually control a specific port sequence number indicator.
• If a 40GE or 100GE port is not split, the port indicator shows the status of the 40GE or 100GE port.

• 40GE QSFP+ optical modules
• QSFP+ to QSFP+ AOC cable
• QSFP+ to 4*SFP+ AOC cable
• QSFP+ to QSFP+ high-speed cable
• QSFP+ to 4*SFP+ high-speed cable

When one of the 18 40GE ports (0, 1, 4, 5...) on the card works in 100GE mode, it can use:

• 100GE QSFP28 optical modules
• QSFP28 to QSFP28 AOC cable

If all LPUs are these cards:

• The CloudEngine 16804 chassis provides a maximum of 144 40GE ports.
• The CloudEngine 16808 chassis provides a maximum of 288 40GE ports.
• The CloudEngine 16816 chassis provides a maximum of 576 40GE ports.

A 40GE port on the card can be split into four 10GE ports. That is, a card provides a maximum port density of 144 x 10GE. All the 36 40GE ports are independent, and each can be split into four 10GE ports.

On the card, the 18 40GE ports that can be used as 100GE ports are marked with silkscreen 40/100G. The port IDs are 0, 1, 4, 5, 8, 9, 12, 13, 16, 17, 20, 21, 24, 25, 28, 29, 32, and 33. These port IDs are represented by (0, 1, 4, 5...) in the following descriptions.

The 36 ports on the card are divided into groups, each of which contains four ports starting from port 0. The total port rate of a group cannot exceed 200GE. When port n is used as a 100GE port, port n+2 becomes unavailable and is in DOWN(Port unavailable) state.

For example:

Ports 0 to 3 are in the same group. If ports 0 and 1 are used as 100GE ports, ports 2 and 3 become unavailable and are in DOWN(Port unavailable) state.

If only one port (for example, port 0) is used as a 100GE port, port 2 becomes unavailable and is in DOWN(Port unavailable) state. Ports 1 and 3 can work as 40GE ports or each of them can be split into four 10GE ports.

When 18 ports on an LPU are configured to work at 100 Gbit/s, the other 18 ports are configured to work at 40 Gbit/s, and all these 36 ports work at the same time, they cannot forward data at the line rate.

Ports 0 to 11 are in a group, ports 12 to 23 are in a group, and ports 24 to 35 are in a group.

• When the total port bandwidth of each group does not exceed 480 Gbit/s, SFUs can forward data at the line rate in the 4+1 backup mode.
• When the total port bandwidth of each group does not exceed 600 Gbit/s, SFUs can forward data at the line rate in the 5+1 backup mode.
