c.
Check for possible Ethernet MAC Address collisions.
If the Frame ID Memory chip installed on the rear of the frame is
missing or has failed, the frame adopts the default Ethernet MAC
Address.
If more than one frame in the Network adopts the default Ethernet
MAC Address, there could be address resolution problems. Upon
power up the frame will indicate in the serial port console window,
either:
“MAC ADDRESS IS UNIQUE!” – THE FRAME HAS SUCCESSFULLY
RETRIEVED A UNIQUE ETHERNET MAC ADDRESS FROM THE FRAME ID
MEMORY CHIP
or
“MAC ADDRESS IS DEFAULT!” - THE FRAME IS USING THE DEFAULT
ETHERNET MAC ADDRESS. THE FRAME ID MEMORY CHIP IS MISSING OR
HAS FAILED. CALL GRASS VALLEY GROUP CUSTOMER SERVICE

pages for a module in the remote lockout state will indicate that
module remote control is disabled and the module’s controls on the
web pages will be in read-only mode.

remote lockout state. In this state, software updates to the modules and
the 8900NET module are also locked out.

control is disabled.
If so, flip Switch 3 on the S2 DIP switch block (FRAME CNTRL) to
the enabled setting.

If it is only a specific parameter that is read-only, the module may be in
a mode assigning read-only operation to that parameter. Refer to the
module’s instruction manual.
3.
If only the 8900NET module is read-only, the 8900NET module may be
in remote lockout mode.
