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.

Ethernet test results
- All tests are done with Xena Networks specialized test equipment (XenaBay),and done according to RFC2544 (Xena2544)
- Max throughput is determined with 30+ second attempts with 0,1% packet loss tolerance in 64, 512, 1518 byte packet sizes
- Test results show device maximum performance, and are reached using mentioned hardware and software configuration, different configurations most likely will result in lower results
The device has an operating system preinstalled and licensed. No separate purchase is necessary and the product is ready to use. The device includes free software updates for the life of the product or a minimum of 5 years starting from date of purchase..
