 Note:
z When the SRPU of the S7500E switch is LSQ1SRP1CB, it is recommended not to
modify the default working mode the EA LPUs as other modes.
z When the SRPU of the S7500E switch is LSQ1SRP2XB, LSQ1SRPB, or
LSQ1MPUA, if an EA LPU is connected to a Layer 2 forwarding network with a large
number of MAC addresses, you can modify the working mode of the EA LPU from
the default to the MAC extension mode.
z To make the configured working mode take effect, you need to save the
configuration and restart the switch.
3.2.9 Identifying and Diagnosing Pluggable Transceivers
I. Introduction to pluggable transceivers
At present, four types of pluggable transceivers are commonly used, and they can be
divided into optical transceivers and electrical transceivers based on transmission
media as shown in
Table 3-3.
