Differences between LE0DG48TBC00 and LE0DG48SBC00 LPUs

Most of the cards of different switches are not interchangeable. You can use Hardware Query Tool to query cards for specified models.

S7700&S9700 LPUs are classified into three series: E series, F series, and S series. The E series is the enhanced series, which supports Multiprotocol Label Switching (MPLS) and extension of routing, ACL, as well as MAC address entries. The E series consists of the EA, EC, ED, and EE LPUs. The F series is the ordinary series, and supports MPLS but not extension of MAC address entries. The F series consists of the FA and FC LPUs. The S series is the standard series and does not support extension of MAC address entries. The S series consists of the SA and SC LPUs. The SA LPUs do not support MPLS, whereas the SC LPUs support MPLS. NOTE: A, C, and D in the LPU names indicate the number of MAC address entries supported by the LPUs: A: 32K MAC addresses C: 128K MAC addresses D: 512K MAC addresses

For S series switches, if LPUs installed in a switch support different numbers of multicast forwarding entries, the number of multicast forwarding entries supported on all LPUs changes to the minimum number supported by these LPUs. It is recommended that you install only LPUs with high specifications on a switch when users connected to the switch order a large number of multicast programs.

- In MPU connection mode, management links and forwarding links are separated, ensuring high reliability. SIP ports on the MPUs and service ports on the LPUs must be connected for member switches. - In LPU connection mode, management links and forwarding links are integrated. Only service ports on the LPUs are connected for member switches.

IN_PWR_ABN is the predecessor of IN_PWR_LOW/IN_PWR_HIGH. Due to historical reasons, both alarms exist in the OptiX OSN 8800.
