signal to one another to verify link integrity. The rear panel is fitting with two LEDs to monitor the
Ethernet connection.
LINK-UP (AMBER):
This LED is ON when the module has established a good link to its supporting
hub. This provides a good indication whether the segment is wired correctly or not. The
LED is OFF if there is no valid connection.
ACTIVITY (GREEN):
This LED provides information on link traffic activity. It blinks when the module is
transmitting or receiving packets. The blinking speed is relative to link activity. The more
traffic there is no the link, the faster the LED blinks. The LED is be OFF if there is no
valid connection or no link activity.
To successfully install any of the 7780MD series modules, user will need:
1. Unused IP address on the network or a DHCP server.
2. Evertz serial cable.
3. VLPRO Server IP address.
The 7780MD Series module is controlled via a 780x Frame controller and cannot
be controlled directly through its own control port.

HARDWARE INSTALLATION
Before handling the card it is important to minimize the potential effects of static electricity. It is
therefore recommended that an ESD strap be worn. Locate on the 7800 chassis two adjacent vacant
slots. Unpack the 7780MD and separate the rear panel from the main card. Locate on the rear of the
rack an empty slot and remove the blanking panels. Insert the rear panel into the back of the chassis
and secure using the screws provided.
Before inserting the front card, connect the serial cable provided to the board. Now insert the 7780MD
Series card into the corresponding front slots ensuring the card lines up with the slot runners on the
bottom and the top of the chassis. Push the card into the slot ensuring that when it mates with the rear
card that it has been firmly pushed into a seated position. This can be confirmed when the connectivity
lights for the Ethernet port are illuminated. Do not connect any cables to the rear card until the initial
configuration has been completed (failure to do this could cause unwanted network issues).
