NOTE:
The fiber-optic and electrical connections that a 10/100/1000 Mbps Ethernet interface provides cannot
be used at the same time. If both connections are present, you can configure which connection takes effect
through commands. By default, the electrical connection works.
5. Compact Flash (CF) slot
The MPUF provides one CF (PCMCIA) slot for a hot swappable CF card.
A CF card can store application programs, configuration files, and log information. With it, you can
conveniently perform such operations as online upgrade and log management.
CAUTION:
Do not remove a CF card during its read or write operation; otherwise, data loss and even hardware
damage will occur.
6. USB interface
MPUF provides two USB 1.1 interfaces: USB1 for Host and USB0 for Host and Slave that can be
configured. USB LED is valid only when USB0 is set to Slave.
