Euphonix CO-600 Change-Over System For New Core DF66 Redundancy

Completely remove the card being careful not to touch any electronics on the card or
neighboring cards in the process. Once the card is completely removed, and anti-static
handling precautions are observed, any changes requiring handling of the cards can be
made.
To re-insert the card, align the Card PCB up with matching groves in the slot hardware.
Push the card in smoothly and carefully with the lightest touch possible so as not to flex
the PCB or allow any conductive material to touch the card. When the card is almost
inserted, resistance will increase and the blue “OOS” LED will light. Do not fully insert
the card until this LED lights.
Use the hooks on the ejector levers to leverage the card in against mating holes in the slot
frame. When the ejector levers are fully inserted, they will click and lock. When this
is done for both front and rear cards, it will trigger the software to automatically power
up the card.
Hot swapping is the same for front and rear cards. But, note that the ejectors are levered
differently on the rear cards.
Hot Swapping Controller Card
The Controller Card can be hot swapped. Removing a Controller Card will cause all
the switch cards to bypass their connection to the DSP Bank “A”. This is exactly what
would happen if the power were disconnected.
Firmware Upgrade
Controller and Switch Card firmware can be field upgraded by Ethernet control only.
The current version number will be output the serial port on boot or when commanded.
Ethernet Control
This is used by Emix and MaxAir to control the CO in normal operation.
Ethernet connection
The COS supports DHCP or static addressing and will hold its IP address through power
cycles. IP address, network sub net mask, and gateway address can be configured through
the serial or Ethernet interfaces.
It is a typical problem with Ethernet controlled devices that once configured with an IP
address, it is difficult to change the configured address if the device is moved to another
network sub net, or if the Ethernet control is only used infrequently by one or more
laptop computers. There are features on the Controller Card to ease this issue.
First DHCP is supported so that an IP address can be automatically assigned based on
the connected network. But leaving DHCP enabled is a problem if connected directly to
