Safety Information
Keep the device away from water, re, humidity or hot environments.
Do not attempt to disassemble, repair, or modify the device. If you need
service, please contact us.
Avoid using this product during an electrical storm. There may be a remote risk
of electric shock from lightning.
Specications
The 10G RJ45 SFP+ modules consume more power than optical modules. This may result in higher heat. To avoid overheating, it is recommended to place the
modules separated by multiple optical transceivers or empty slots.
When used in high temperature environments, additional cooling must be applied.

When a 10G RJ45 SFP+ module is used at 100 Mbps/1 Gbps, extra
conguration for port data rate may be required. And
when it is inserted into a
10 Gbps SFP+ slot and the maximum rate of the peer connection port is 5
Gbps, 2.5 Gbps, 1 Gbps, or 100 Mbps, the ow control for the 10 Gbps SFP+
slot needs to be manually enabled.
When a gigabit RJ45 SFP module is inserted into a 10G SFP+ slot, extra
conguration for port data rate may be required.
**
Note:
TL-FM531 does not support the data rate of 10 Mbps or 100 Mbps.
