3. Unlock the handles by pressing the red button on each handle. The button immediately activates the
switch (turning it to an open position), while the button itself remains depressed. The blade can then
be removed.
4. Remove the malfunctioning Model 3196RC by pushing the handles outwards, pulling the card gently but
firmly from its slot in the chassis. Place the removed card in the container the replacement Model 3196RC
came in so you can return the defective Model 3196RC for repair.
Installing the replacement Model 3196RC
1. Insert the replacement Model 3196RC into the rack chassis.
2. Insert the rear blade into the desired slot in the rack chassis. Make sure the blade is seated properly in the
slot guides.
3. Gently press the blade into the chassis until the alignment/ESD pin engages the chassis. When the blade is
fully seated, the red buttons in the handles click up automatically, thus locking the handle and activating
the switch (closed position). The click of the button gives a visual and audible confirmation that the board
is fully seated.
4. Connect the following cables to the Model 3196RC:
– The T1/E1 WAN cable (68-pin SCSI connector)
– The iDSL modem cable (RJ-21X connector)
– The RS-232 CONFIG cable
– The 10/100 ETHERNET cable
5. Verify that the green POWER LED is lit.
