Hi Kashif
1. serial cable failover is just checking a voltage heartbeat between the two systems. in network failover the hearbeat is a network packet, and depending on what version of bigip you've got the packet is different e.g. udp 1026
2. If you use both then effectively network failover is redundant and won't be used as it would need the serial failover to also fail.
3. there is a distance issue, serial failover can only be used to around 50ft (i think) so in your case then you could only use network failover.
Hope this helps,
N
