Installation manual
Authorized Service Personnel ONLY:
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. The factory 
default IP is fixed as 192.168.0.160. 
Using Two Changeover Switches with Emix or Max 
When using a system with more than one changeover switch (i.e. changing over 5 or 6 
DSP cards), the second changeover switch’s IP address must be set to 192.168.0.161. 
This is done at the factory. If for any reason the IP address needs to be set in the field, 
the user must install two jumpers, H12 and H14 (if not already installed), on the frame 
controller card.  Then using FrameMon software (available from Euphonix), change the 
address to the new value. Leave the jumpers in place to retain the new value.  Removing 
the jumpers will reset the IP value back to the factory default of 192.168.0.160.
