Hi,
I agree with Priscilla.
I don't think it's an ARPing problem.
Try using the extended PING command to make sure you ping from the correct
interface.
Also, you can try checking the ARP entry for the 3COM router on the Cisco
router to see if there are any changes before and after the PING

If I remember correctly, 172.16.2.0/24 showed up in peter's route table.

Pix 515 uses the same power supply that Cisco 2500s and Cisco 2600s routers

A 515 chassis looks a lot like a 2600. Maybe they share the same PS. Further
