Board Replacement

When replacing the cPCI board, note the following:
The VCX V7122/SIP cPCI board, which is also the TP-1610 cPCI board, is hot-
swappable, meaning that the board can be inserted and removed when the VCX
V7122/SIP chassis is under power.
When removing the cPCI board from the cPCI chassis, press the two red latches and
wait for the blue LED to light, indicating that the board can be removed.
When inserting the cPCI board into the cPCI chassis, press the two red latches and
insert the board. Wait for the blue LED to light, indicating that the board has been
inserted correctly.

Optional CPU Board

The VCX V7122/SIP provides an optional second cPCI slot that can be used for a
customer's CPU board. This CPU board can be used for general applications such as a SIP
Proxy, Softswitch, or an application server. The following CPU boards were tested for
compliancy with the VCX V7122/SIP chassis:
Sun – CP2080 + PMC-233 (Ramix disk on board)
Motorola – CPV5375-700-02 (with integral HDD) + CPTM-01 (RTM)
