Equipped with 8 RJ45 PoE-out ports, this switch supports various power outputs including autosensing 802.3af/at PoE/PoE+ and Passive PoE. With 4 SFP cages, it extends the advantage of optical fiber connectivity, ensuring uplink speeds of up to 1 Gbps. Containing 12 independent switching ports and a 400MHz CPU backed by 128MB RAM, it guarantees smooth operations. The package includes a 28 V 3.4 A power supply, with an option to integrate a secondary 48-57 V supply. Given its features, it’s a top choice for businesses aiming for flexibility, power, and efficiency in their networking setup.

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 – product codes 48POW (1.46A 70W) and 48V2A96W (2A 96W)). 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
