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.
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).
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 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.
All the feature set comes with disruptive price, providing best price/performance on the market.
The UltraLAN SG08PAI+2GE-96W is a 10 port switch with 8x 802.3af/at PoE ports and 2x Gigabit RJ45 uplink port.
The 802.3af/at ports will auto detect and identify IEEE802.3af/at devices before supplying any voltage, therefore you do not have to worry about damaging your Non-PoE equipment.
Total maximum PoE budget is 96W and the maximum budget per port is 36W.
AI is an integrated intelligent port monitoring protocol, AI monitors traffic on each individual port of the switch and if no traffic passes through the interface after 120 seconds the port is automatically reset, as a result the non responding device receives a hard reboot and comes back online automatically.
The benefits of AI are twofold: With a traditional switch the entire switch must be reset which means ALL devices go offline (including even perfectly functioning devices), it is also typically a manual process requiring human intervention which means downtime is significantly longer and in remote locations particularly cumbersome and costly.
AI can significantly increase system uptime while massively reducing system downtime.
AI functionality can be activated and deactivated via a toggle switch on the device.
AI Extend: 1-8 ports can be extended to support cable length of up to 250 meters, bare copper cable is recommended AI VLAN: Isolating ports 1-8 from each other can effectively suppress network storms and improve network performance.
AI QoS: Customize application priority to improve network sensitivity.
For example, video priority will take preference over other protocols AI power: Monitor each port on the switch for traffic and if no traffic is detected power off and restart the device
