What are differences between the MPU connection mode and LPU connection mode of CE12800 member switches
- 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.

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

What are the differences between the E series, F series, and S series LPUs of the S7700&S9700
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

Will the number of multicast forwarding entries supported on each LPU change when an S series switch has different types of LPUs installed
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.

Differences between IN_PWR_LOW differ from IN_PWR_ABN
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.
