Difference between NIC Down and Down(PWR OFF) state on an ADC hardware appliance

Question:

In an MPX or SDX ADC appliance physical interface, what is the difference between the DOWN and DOWN(PWR OFF) state as highlighted below?

Interface 1/5 (Gig Ethernet 10/100/1000 MBits) #1

flags=0x4000 <ENABLED, DOWN, down, autoneg, HEARTBEAT, 802.1q>

MTU=1500, native vlan=1, MAC=00:e0:ed:7a:1b:43, downtime 83h09m57s

Requested: media AUTO, speed AUTO, duplex AUTO, fctl OFF,

throughput 0

LLDP Mode: NONE, LR Priority: 1024

RX: Pkts(0) Bytes(0) Errs(0) Drops(0) Stalls(0)

TX: Pkts(0) Bytes(0) Errs(0) Drops(0) Stalls(0)

NIC: InDisc(0) OutDisc(0) Fctls(0) Stalls(0) Hangs(0) Muted(0)

Bandwidth thresholds are not set.

Interface 1/1 (Gig Ethernet 10/100/1000 MBits) #5

flags=0x4100 <disabled, DOWN(PWR OFF), down, autoneg, HEARTBEAT, 802.1q>

MTU=1500, native vlan=1, MAC=00:e0:ed:7a:1b:47, downtime 83h09m57s

Requested: media AUTO, speed AUTO, duplex AUTO, fctl OFF,

throughput 0

LLDP Mode: NONE, LR Priority: 1024

RX: Pkts(0) Bytes(0) Errs(0) Drops(0) Stalls(0)

TX: Pkts(0) Bytes(0) Errs(0) Drops(0) Stalls(0)

NIC: InDisc(0) OutDisc(0) Fctls(0) Stalls(0) Hangs(0) Muted(0)

Bandwidth thresholds are not set.

Answer:

If an interface is Enabled and Down, it displays it as Down state.

If an interface is Disabled and Down, then it is displayed as Down(PWR OFF) state.
