Description
MikroTik’s CRS328-24P-4S+RM is a 28 port independent switch. It offers 24 Gigabit Ethernet ports with different power output options: Passive PoE, low voltage PoE, 802.3af/at (Type 1 “PoE” / Type 2 “PoE+”) with auto-sensing. PoE-Out is passed over mode B pins (4,5+)(7,8-).
The four SFP+ ports provide up to 10 Gbps connectivity options via either optical fiber or Ethernet modules (not included).
The 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 (3×150 W per every 8 Ethernet ports) to power your PoE devices. Each port can provide up to 30 W of power with any power output option you choose.
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. Package Contents 1x UK Power Supply 1x CRS328-24P-4S+RM 2x Rack Ears Product Features 24 Configurable PoE Out Ports 4 SFP+ Upload Ports Dual Boot Function.
