Support For Lm4 Optics; Example Scenarios - Dell Z9000 Configuration Manual

Support for LM4 Optics

The newly supported LM4 optics are similar in behavior to the LR4 optics that are already supported.
However, in the output of show inventory media command, an LM4 optical module is denoted as
40G-LM4. Barring this exception, the functionality and behavior of LM4 optics is similar to LR4 optics.

Example Scenarios

Consider the following scenarios:
• QSFP port 0 is connected to a QSA with SFP+ optical cables plugged in.
• QSFP port 4 is connected to a QSA with SFP optical cables plugged in.
• QSFP port 8 in fanned-out mode is plugged in with QSFP optical cables.
• QSFP port 12 in 40 G mode is plugged in with QSFP optical cables.
For these configurations, the following examples show the command output that the show interfaces
tengigbitethernet transceiver, show interfaces tengigbitethernet, and show
inventory media commands displays:

SFP+ 0 Temp High Alarm threshold
SFP+ 0 Voltage High Alarm threshold
SFP+ 0 Bias High Alarm threshold
NOTE: In the following show interfaces tengigbitethernet commands, the ports 1,2, and 3
are inactive and no physical SFP or SFP+ connection actually exists on these ports. However, Dell
Networking OS still perceives these ports as valid and the output shows that pluggable media
(optical cables) is inserted into these ports. This is a software limitation for this release.
