CRS328-24P-4S+RM CRS328-24P-4S+RM is a 28 independent port switch it has 24 Gigabit Ethernet ports which offer different power output options: Passive PoE low voltage PoE 802.3af/at (Type 1 “PoE” / Type 2 “PoE+”) with auto-sensing. The four SFP+ ports provide up to 10 Gbps connectivity options via either optical fiber or Ethernet modules (not included). CRS328-24P-4S+RM comes in a 1U rackmount case with 100-240 V AC 500 W power supply built-in. The device consumes up to 44 W leaving guaranteed 450 W (3x150 W per every 8 Ethernet ports) to power your PoE devices. Each port can provide up to 30 W with high voltage and 26 W with low voltage power output. The device has a “Dual boot” feature that allows you to choose between two operating systems - RouterOS or SwOS. If you prefer to have a simplified operating system with only switch specific features use SwOS. If you would like the ability to use routing and other Layer 3 features in your CRS use RouterOS. You can select the desired operating system from RouterOS from SwOS or from the RouterBOOT loader settings. All the feature set comes with our disruptive price providing best price/performance on the market.
