24xGiga (24x PoE+) + 4xGb 440W IEEE802.3at SNMP 19"

PLANET GS-4210-24PL4C on 28-porttinen SNMP-hallittava 
PoE+ kytkin, jonta 24x 10/100/1000Base-T porttia ovat 
varustettu PoE+ virransyöttötuella. Kytkimen PoE- 
virransyöttökapasiteetti on 440W, joka mahdollistaa kaikkiin
PoE-portteihin maksimissan 30.8W tehon. Kytkimessä on 
lisäksi 4x SFP/TP-porttia valokuitu- ja runkoyhteyksille.
