Make sure that you use a valid combination for the direct attach cable and
the Switch.
The following Switches support SFPP-CU1M/3M/5M. Use the transceivers only with the
indicated Switches. Not doing so could result in a Switch malfunction.
• AX3650S-24T6XW (Supported ports: 25 to 30)
• AX3650S-20S6XW (Supported ports: 25 to 30)
• AX3650S-48T4XW (Supported ports: 49 to 52)
• AX3830S-44XW (Supported ports: 1 to 44)
• AX3830S-44X4QW (Supported ports: 1 to 44)
The following Switch supports QSFP-CU35C/1M/3M/5M. Use the transceivers only with the
indicated Switch. Not doing so could result in a Switch malfunction.
• AX3830S-44X4QW (Supported ports: 49 to 52)
Make sure that you use a valid combination for the transceiver and the
Switch.
The following Switches support SFP-FX and SFP-FX(T). Use the transceivers only with the
indicated Switches. Not doing so could result in a Switch malfunction.
• AX3640S-24SW (Supported ports: 5 to 24)
• AX3640S-24S2XW (Supported ports: 5 to 24)
• AX3650S-20S6XW (Supported ports: 1 to 20)
The following Switches support SFP-SX2 and SFP-SX2(T). Use the transceivers only with the
indicated Switches. Not doing so could result in a Switch malfunction.
• AX2430S series switches
• AX3630S series switches
• AX3640S series switches
• AX3650S-20S6XW (Supported ports: 1 to 20)
Do not turn off the switch while the ST1 LED is blinking green (turning on
for 0.5 seconds and off for 0.5 seconds).
In the following case, do not turn off the power until the ST1 LED on the front panel of the

• While software is being updated
When carrying or packing a Switch and its optional modules, wear a wrist
strap to protect against static electricity.
• Be sure to wear an antistatic wrist strap. If you handle the Switch without wearing an
antistatic wrist strap, the Switch might be damaged by static electricity.
When carrying and packing optional modules, handle them carefully.
• Do not touch a connector when carrying or packing a transceiver, direct attach cable,
memory card, power supply unit, fan unit, or power supply module. Also, when storing an
optional module, use an antistatic bag.
Use care when handling an air duster.
• Use an air duster specially designed for cleaning optical connectors. Using another type of
