The following illustration shows the port-side view of the SLX 9250 Switch models.
| 1 = 40Gbps/100Gbps QSFP28/QSFP+ Ethernet ports | 2 = Console port: RJ45 |
| 3 = USB port | 4 = Management port: RJ45 |
Most of the front-panel ports on the SLX 9250-32C Switch operates in either 100 gigabit or 40 gigabit mode, and each port can be partitioned into data lanes through the use of breakout cables. This means that a given physical port can correspond to either two or four logical ports.
In 100-gigabit mode, each port can be partitioned into four 25-gigabit data lanes.
In 40-gigabit mode, each port can be partitioned into four 10-gigabit data lanes.
Logical port numbers are assigned depending on whether the physical ports are partitioned into data lanes. If there is no partitioning/channelizing, the logical port numbers correspond to the physical port numbers shown on the front of the switch. With partitioning/channelizing, logical port numbers are assigned for each of the physical ports as shown, for example in Table 7 below.
| Physical Port Number (on switch) | Logical Port Number Range when Partitioned by... | |
|---|---|---|
| 4 x 10 Gb | 4 x 25 Gb | |
| 1 | 1,2,3,4 | 1,2,3,4 |
| 2 | 5,6,7,8 | 5,6,7,8 |
| 3 | 9,10,11,12 | 9,10,11,12 |
