Is that $2.0b for network equipment by increasing it's depreciation period by 20%? Meanwhile increasing the deprecation period of servers by 50% only nets $1.0b

Is that $2.0b for network equipment by increasing it's depreciation period by 20%? Meanwhile increasing the deprecation period of servers by 50% only nets $1.0b? I had the impression that servers were vastly more expensive than network equipment. I wonder what the breakdown is for network equipment.
