| Functions and Features |
| Basic function |
Provides 72 x 25GE SFP28 ports on the line side. Each SFP28 port can work at the rate of 25 Gbit/s, 10 Gbit/s, or 1 Gbit/s. |
| Reliability and availability |
Hot swappable. |
| Restrictions and remarks |
1. All ports can work in 25GE, 10GE LAN, 10GE WAN or GE mode. |
| 2. Starting from port 0, every four adjacent ports form a port group. Each port group supports two working modes: 25GE/10GE mode (default). In this mode, each port in each port group can be configured as 25GE/10GE. 10GE/GE mode (which can be switched using the port-mode card-id group-id command in the slot view): In this mode, ports in a port group can be configured to work in 10GE or GE mode. Each port group can be switched between 10GE LAN and 10GE WAN. The combination of 10GE LAN and 10GE WAN is not supported. |
| 3. 10GE WAN interfaces support only the master clock. |
| SFP28 optical modules are used for 25GE ports, SFP+ optical modules are used for 10GE ports, and SFP optical modules are used for GE ports. Some ports (18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48 and 51) on electrical modules support SFP28 optical modules. |
| 5. A fiber extractor is required to remove and insert a fiber. |
| 6. Before removing or inserting a board using an ejector lever, remove the optical module (2, 5, 8, 11, 14, 17, 20, 23, 26, 29, 32, 35, 38, 41, 44, 47, 50, 53, 56, 59, 62, 65, 68 or 71) close to the ejector lever. |
