CMICR-4PC Cisco Catalyst Micro Switch, 4-Port PoE+

CMICR-4PC is a Cisco Catalyst Micro Switch for wall-jack deployments. It has four 10/100/1000 access ports that deliver PoE+, plus one copper and one SFP Gigabit uplink. It ships with LAN Lite software and is powered through a DC connector from an AC/DC adapter with IEC plugs for 100 to 240 VAC inputs.

Micro Switches are built for fibre-to-the-desk deployments, where the switch sits next to the end device instead of in a distant wiring closet. The design is fanless and silent, with up to 30 W per port, and the wall-jack models have up to a 60 W PoE budget. Perpetual PoE keeps endpoints powered through reloads, and Fast PoE restores power within 5 seconds after a power loss.

Forwarding bandwidth is 6 Gbps and switching bandwidth 12 Gbps full duplex, with a forwarding rate of 8.928 Mpps for 64-byte packets. The switch has 256 MB of flash and 512 MB of DRAM, 8192 MAC entries, four port channels, up to 64 VLANs with IDs 1 to 4094, an MTU of up to 1500 bytes and 4 egress queues per port.

The unit measures 1.79 x 3.54 x 3.10 in (4.55 x 9.0 x 7.88 cm) and weighs 0.60 kg. The mounting option for CMICR-4PC is DIN rail. Available passthrough PoE power is 62 W with the Cisco 80 W adapter (PSU-L-80W-ADPT) or the 74 W adapter (PSU-L-74W-ADPT), and 50 W with a third-party 65 W adapter.

The CMICR-4PS version of the wall-jack switch has two SFP uplinks and a cable duct mount, while CMICR-4PT is the desktop version.
