For those work­ing in busi­ness IT, flex­i­bil­ity is the name of the game, be­cause for what­ever rea­son, many com­pa­nies don’t in­volve their tech­ni­cal peo­ple in busi­ness plan­ning and then jackin-a-box their de­mands on them when they make changes.

A typ­i­cal in­stant re­quire­ment is the re­lo­ca­tion of peo­ple and their sys­tems to parts of the build­ing where there aren’t lots of Eth­er­net ports.

New ca­bling is one op­tion, but short timescales can mean a bet­ter one is to use a prod­uct like the Linksys 8-port Desk­top Gi­ga­bit PoE Switch, the LGS108P.

From the out­side, this ap­pears very sim­i­lar to the types of switches many home users might de­ploy, but looks can be de­ceiv­ing. What it shares with those in­ex­pen­sive ex­pen­sive op­tions is the 8 ports of 10/100/1000 Eth­er­net con­nected via a high-per­for­mance back­bone (16Gbps in this case) and the typ­i­cally un­der­stated aes­thetic.

How­ever, pro­fes­sional IT needs re­quire more than con­nec­tiv­ity, and to that end Linksys added 802.1p and DSCP qual­ity of ser­vice func­tion­al­ity.

But the real en­hance­ment here is that the first four ports of this de­vice are PoE (power over Eth­er­net), and in­cluded in the box is a larger than ex­pected PSU to pro­vide the 50 watts ex­tra that the LGS108P can send along with data.

For those won­der­ing if send­ing power over Eth­er­net is a good idea, there are safe­guards in place un­der the IEEE 802.3at (PoE+) stan­dards it was built on.

Orig­i­nal PoE de­signs re­duced the data band­width by re­quir­ing de­dicted wires, but in this de­sign at gi­ga­bit speeds all wires are used for power and data us­ing a method called the ‘Phan­tom tech­nique’.

What PoE pro­vides is an easy means to de­ploy equip­ment where there isn’t a con­ve­niently placed power socket but where you can eas­ily send an Eth­er­net ca­ble.

The ob­vi­ous uses are se­cu­rity cam­eras and VoIP tele­phones, but there are lots of PoE-pow­ered giz­mos to choose from.

If the four PoE or eight data con­nects are in­suf­fi­cient for your needs, then Linksys also has the LGS116P and LGS124P that ex­pand data con­nec­tiv­ity to 16 and 24 ports re­spec­tively and bump back­bone band­width up ac­cord­ingly. They also have more PoE sup­port­ing ports (eight and 12) and a greater power bud­get to di­vide be­tween them.

The only mi­nor blot on this man­i­cured land­scape is that all these switches are un­man­aged, so they’re not re­ally de­signed to be at the cen­tre of a net­work but more pe­riph­eral.

Dis­crete and eas­ily wall mount­able, this is ex­actly the sort of hard­ware that an IT man­ager needs on the shelf when the call comes that they’ve hired a new tele­sales team and its go­ing where there is lit­tle or no in­fra­struc­ture to sup­port them.

Given the pre­mium cost that PoE hard­ware is as­so­ci­ated with, this hard­ware is also rather cheap, and there­fore po­ten­tially of in­ter­est to any­one who is in­stalling a home se­cu­rity sys­tem in their own prop­erty.
