cisco 1921 powering 1602e poe

Hello Team,

I would like to know if i can power  a 1602e AP on a cisco 1921 ISR (base/k9)?

I do not have any Ehwic or hwic installed.

I do not have extra power supply (only basic c1921/k9.

No power injector Air-pwrinj5.

I would like to know using Gig0/1 is it possible to poe the access point using the port itself?

It is stated that the air-pwrinj5 has a 15.4 Watt output.

And it's stated that the C1921/k9 is capable to supply 15.4 Watt directly out of the box without any additional power injector or power supply.

 

Thanks

As long as your Ethernet

As long as your Ethernet ports supply 802.1af your good. I have a 1941w and had to purchase a gigabit PoE module in order to power up devices.

You need a switch PoE module.

You need a switch PoE module. The default ports on the 1900 doesn't support PoE.

Hi Scott,Meny thanks for the

Hi Scott,

Meny thanks for the quick reply and helpful advice.

That's what i'm asking(didn't find any concrete info also in cisco official doc) is the Gigabit Ethernet0/1 on the 1921 with base software able to supply poe 802.af without any power supply or module?

from the official cisco docs:

"

Architecture and Modularity

The Cisco 1921 is architected to meet the application demands of today's branch offices with design flexibility for future applications. The modular architecture is designed to support expanding customer requirements, increased bandwidth, and fully integrated power distribution to modules supporting 802.3af PoE and Cisco Enhanced PoE (ePoE). Table 2 lists the architectural features and benefits of the Cisco 1921"
 
what does it mean? EHWIC moduls or in my case  simply connecting an AIR-CAP1602E-E-K9 (I know that's not standalone image and need to have a WLC controller)
And i was unable to kickstart the access point(i don't have a power supply for the AP neither power injector (air=pwrinj5=).
Can one poweron a 15.4Watt poe device without additional power supply or power injector?
Running 15.2(4)M4 from 2013 on the 1921 router.
Thanks again.

Would i need an extra power

Would i need an extra power supply such as the PWR-1900-POE  or the build in (that comes with the 1921isr) power supply will do the job?

that is if using  EHWIC-4ESG-P module? 

I mean I have a need to power an 15.4watt access point now but not more. some devices maybe later on. 

Since the modules and power supply adapters are relative expansive and i wouldn't like t invest extra money.

Thx

You would need a power supply as that is what was required on my 1941. Your better of buying a power injector for that AP or even cheaper, the AC power plug.

I would go for the power

I would go for the power injector.

Scott, are you using an EHWIC-D-8ESG-P?  

and if so what else needed in addition to the EHWIC-D-8ESG-P (par-1900-poe?)

The info is a bit confusing about which power supply is needed for which ehwic/hwic.

reading here seems so just would like to have confirmation.

WIC Switch"                                                                     
PID: EHWIC-D-8ESG-P 

You need the PoE power supply also or else the module will not work.
