Gigabit on 3560 switch line protocol is down (disabled)

I have been having an issue where I have a SPF cable from switch to switch that shows port administratively shutdown here is a show interface:

GigabitEthernet0/3 is administratively down, line protocol is down (disabled)
Hardware is Gigabit Ethernet, address is 001b.0c0d.e71b (bia 001b.0c0d.e71b)
Description: Dot1Q Link to Data2Floor2

Keepalive not set
Auto-duplex, Auto-speed, link type is auto, media type is 1000BaseCX SFP Cable
input flow-control is off, output flow-control is unsupported
ARP type: ARPA, ARP Timeout 04:00:00
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

I have tried many things to change this. any help would be great. I tested the cable on a different set of switches and the link came right up.

Bad hardware. RMA that sucker.

it failed POST - "power on self test"

You cannot repair that.
