POE injectors

[Koldov]

We are having Paxton added to our external gates over the summer.

 

To enable this we are required to provide 2 x POE ports.

 

The nearest available switch (and therefore shortest cable run) has no POE ports.

 

To enable access to the POE ports would require something like (at least) another 100ft and everything that entails (meaning a total run of 150ft+).

 

Does anybody know if it's possible to use injectors with a Cisco 2960 (I know, I know, but I'm working with what I've got for now) and if so, should I suggest them for the ports on the nearer switch?

Injectors should work with pretty much anything, it's just putting power over the pairs. The switch will be oblivious to the POE

Injectors tend to just work with whatever switch you're using. You may need to check that the ports don't disable or block with STP or similar. I've not used them on a cable that long before, and I hoofed them all out when we went to PoE sitewide, but they didn't cause me issues.

Can't you specify powered paxton instead? On the assumption there's already power at those games if paxton is being used, that'd surely be a better all round solution. But if not, you can absolutely use injectors with that or any switch.

Could you place a smaller POE+ switch between the Cisco and the end points? Wouldn't need to worry about the compatibility with the Cisco kit then.

Could place this in a room nearer to the gate's and just uplink from the Cisco via a shorter Cat6 run, or keep everything in one place and put this in the same location as the Cisco.

From the sounds of it it would be POE needed for the intercom not the actual gate? Using an injector is fine.

Exactly this, same train of thoughts https://www.amazon.co.uk/dp/B08PBXMHRR?ref=emc_s_m_5_i_atc

 

Our paxton installers put a PoE switch in and run a cable from the rack switches to the mini switch and power off to these.

Buy a POE switch

 

Intelligent Brokerage in Harrogate sell them at a very good price

Last ones I got, 3750X POE where circa £300

Paxton do make a 4/5 port PoE switch that stacks with the ACU mainboard in the housing.

Yes you physically can run injectors no technical reason why not but they are not good practice and it is just something else to go wrong so you are sacrificing reliability. ( as in 2 x injectors each end and 2 x cheap Chinese power supplies each end to go wrong per drop).
