product description

1: CRS112-8P-4S-IN

Mikrotiks CRS112-8P-4S-IN is an eight Gigabit RJ45 port PoE switch, that offers different power output options: autosensing 802.3af/at PoE/PoE+ and Passive PoE, and four SFP ports provide optical fiber connectivity options to support uplinks of up to 1 Gbps.

CRS112-8P-4S-IN is equipped with 12 independent switching ports. 28 V 3.4 A power supply is already included in the box. There is secondary DC jack on the back of the enclosure that supports 48-57 V power supply (not included, can be purchased separately). CRS112-8P-4S-IN can power 802.3af/at devices if 48-57 V DC input is used (unit will automatically detect and provide correct power to devices). Max current is 1 A per port if input voltage is 18-28 V, 450 mA if 48-57 V. Total limit is 2.8A@24V and 1.4A@48-57V. PoE-Out is passed over mode B 4,5 (+) and 7,8 (-) pins

The maximum current output is 1 A per port when the input voltage is 18-28 V, 450 mA at 48-57 V.
Note: PoE-Out according to 802.3af/at is possible, but for this you still need the optional power supply unit, which is linked below. The supplied and optional power supply units can be plugged in at the same time. The supplied power supply unit supplies the Mikrotik components and the optional one supplies IP telephones/cameras, etc.
For PoE-Out according to 802.3af/at, an additional power supply unit is still necessary, e.g.: https://www.mikrotik-store.eu/en/mikrotik-48v-2a-96w-power-supply-plug

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..
