MikroTik CRS328-24P-4S+RM network switch 24 × 1G PoE+, 4 × SFP+, L3

MikroTik CRS328-24P-4S+RM is a managed L3 network switch with 24 Gigabit RJ-45 ports carrying PoE and PoE+ power and four SFP+ slots. It powers security cameras, Wi-Fi access points and IP phones over a single cable, mounts in a rack and runs either RouterOS or SwitchOS.

  • Ports: 24 × 1 Gbit/s RJ-45, 4 × SFP+
  • PoE: all 24 ports, 802.3af and 802.3at (PoE+), up to 30 W per port
  • Power: single 500 W power supply
  • Management: managed L3, RouterOS (L5) or SwitchOS, VLAN (4000), port mirroring
  • Performance: 128 Gbit/s switching capacity
  • Enclosure: rackmountable, RJ45 console port, 3.826 kg

Description

PoE+ on all 24 ports

Every RJ-45 port supports both PoE (802.3af) and PoE+ (802.3at) and delivers up to 30 W. A camera, Wi-Fi access point or IP phone therefore gets data and power over one network cable, with no separate adapter or wall socket needed next to the device. The switch has a 500 W power supply inside; the manufacturer does not state a separate total PoE budget.

Four SFP+ slots for a fast uplink

Alongside the copper ports, the switch has four SFP+ slots. SFP+ is the 10-gigabit connection standard used to link the switch to a server, a storage system or another switch with an optical module or a direct-attach cable. That way the traffic of 24 Gigabit devices does not get squeezed into a narrow uplink, and a distant network cabinet is easy to reach over fibre.

Two systems: RouterOS or SwitchOS

The switch boots into either RouterOS (L5 licence) or SwitchOS, whichever you choose. SwitchOS is a simpler switch system configured through a web interface, suited to cases where you only need to manage ports, VLANs and PoE. RouterOS unlocks the L3 features and the full depth of MikroTik configuration for those who already run other MikroTik equipment. Which system to use can be decided by how complex the network is.

VLANs and port mirroring to keep the network in order

As a managed L3 switch it supports up to 4000 VLANs, so cameras, phones, the guest network and office computers can be kept apart on the same physical network. Guests do not see the internal company network, and camera video streams do not weigh on office traffic. Port mirroring copies the traffic of a chosen port to another port where it can be analysed, which is essential for troubleshooting and security checks.

Rack mounting, a console port and 128 Gbit/s

The switch mounts in a rack and weighs 3.826 kg. The RJ45 console port lets you configure or recover the device directly over a cable even when there is no network access. A switching capacity of 128 Gbit/s means all ports can run at full speed at the same time. There is a single power supply; this model has no redundant power.

Who this network switch is for

Businesses powering security cameras, access points or IP phones over PoE; IT administrators who need VLANs and L3 features in one rackmount device; and builders of MikroTik networks who want the choice between RouterOS and the simpler SwitchOS. The four SFP+ slots come in handy when a server or another network cabinet needs a fast connection.

Questions & answers

How many cameras or access points can it power?

PoE is available on all 24 ports at up to 30 W per port (802.3af and 802.3at), and there is a 500 W power supply inside. The manufacturer does not state a total PoE budget, so add up the consumption of your devices before installation.

Is the switch managed and does it support VLANs?

Yes. It is a managed L3 switch with support for up to 4000 VLANs and port mirroring.

Can it be mounted in a rack?

Yes, the switch is rackmountable and has an RJ45 console port.

Does it have a redundant power supply?

No. The switch has a single 500 W power supply.
