MikroTik (CRS328-24P-4S+RM) 24 Port Gigabit Ethernet  Switch

The CRS328-24P-4S+RM is a 28-port switch manufactured by MikroTik. It offers 24 Gigabit Ethernet ports and 4 SFP+ ports, providing high-speed connectivity options.

The 24 Gigabit Ethernet ports on the switch support various power output options. These include:

1. Passive PoE: This option allows you to provide power to compatible devices using Passive PoE technology.

2. Low voltage PoE: It offers the capability to supply power to devices that require low voltage PoE.

3. 802.3af/at (Type 1 "PoE" / Type 2 "PoE+"): This option supports the 802.3af and 802.3at PoE standards, commonly known as PoE and PoE+ respectively. These standards provide power to compatible devices over Ethernet cables.

The switch has auto-sensing capabilities, meaning it can automatically detect the power requirements of connected devices and provide the appropriate power output accordingly.

The PoE-Out feature on the CRS328-24P-4S+RM switch passes power over mode B pins (4,5+) and (7,8-). This is the standard pinout configuration used for delivering power over Ethernet cables.

Additionally, the switch is equipped with four SFP+ (Small Form-Factor Pluggable Plus) ports. These ports support up to 10 Gbps (Gigabits per second) connectivity options. You can use either optical fiber modules or Ethernet modules to establish high-speed connections using these ports.

Overall, the CRS328-24P-4S+RM switch offers a versatile and powerful networking solution with a combination of Gigabit Ethernet ports and high-speed SFP+ ports, along with various power output options to cater to different device requirements.
