Step 7
Gently extract the old ROM with a ROM extraction tool and set the old boot ROM on a nonconductive
surface. Do not use excessive force because the socket might break.
Step 8
Insert the new boot ROM into the socket. Be careful not to bend or crush any of the bottom pins. If
necessary, use needlenose pliers to straighten out any bent pins.
Caution
The notch in the ROM must align with the notch in the socket on the system board. If the
ROM is installed backward, damage will occur when the universal gateway is powered ON.
Step 9
Replace any cards removed. (Refer to
Cisco AS5350 and Cisco
AS5400 Universal Gateway Card
Installation Guide
for instructions on installing specific dial feature cards.)
