Recovery Mode
Recovery mode is a fail-safe mode where the router can load a default configuration from the router's firmware.
If the router goes into recovery mode, all config files are kept intact. After the next reboot, the router will
revert to the previous config file.
Use recovery mode to manipulate the config files, but it should only be used if all other config files are corrupt. It
the router has entered recovery mode, contact your local reseller for access information.
3.4.8. SFP Transceivers
Each SFP slot can hold one SFP transceiver. See "Transceiver User Guide 6100-0000" for transceiver handling
instructions, which also can be downloaded from the product support pages at
www.westermo.com/support/
product-support .
In the event of contamination, the optical connectors in the SFP transceivers should only be cleaned by the use
of forced nitrogen and some kind of cleaning stick. Recommended cleaning fluids are methyl-, ethyl-, isopropyl-
or isobutyl alcohol, hexane or naphtha.
CAUTION - HANDLING OF SFP TRANSCEIVERS
SFP transceivers are supplied with plugs to avoid contamination inside the optical port. They
are very sensitive to dust and dirt. If the fibre optic cable is disconnected from the product, a
protective plug must be used on the transmitter/receiver. The protective plug must be kept on
during transportation. The fibre optic cable must be handled the same way.
3.5. LED Indicators
The router has single colour LEDs. When the router is powered on, the power LED is green.
The possible LED states are:
• Off
• Flashing slowly
• Flashing quickly
• On
