The Mercusys MS128GP is a 28-port Gigabit rackmount switch with 24 PoE+ ports. It suits larger CCTV installs, office floors full of VoIP phones and access points, and estates or warehouses where power at every device isn't practical. Ports 1-24 each deliver up to 30 W (802.3af/at) from a 295 W total budget. Two Gigabit RJ45 uplinks and two Gigabit SFP slots connect to your NVR, router or a fibre backbone. Switch-selectable modes add Extend mode, which gives up to 250 m PoE and data for distant cameras. Isolation mode splits ports 1-12 from 13-24. Priority mode favours ports 1-4. PoE Auto Recovery automatically reboots hung cameras or APs across ports 1-24. Switching capacity is 56 Gbps with an 8K MAC table, and it is unmanaged, so it works out of the box. The 1U metal chassis measures 440 x 180 x 44 mm, uses two fans and has an internal power supply. In the box you get the switch, a power cord, an installation guide and rack-mounting brackets with fittings.
