FAQ
How many PoE+ ports does this switch have and what is the PoE budget?
The Cisco Catalyst CMICR-4PC has four PoE+ ports that comply with the 802.3at standard, delivering up to 30 watts per port. The total PoE budget is 60 watts, which means the switch can power multiple PoE devices like IP phones, wireless access points, or security cameras simultaneously while managing power distribution efficiently across all connected devices.
What types of media does this switch support for network connections?
This switch supports both optical fiber and twisted pair media types. It uses Gigabit Ethernet technology with 1000Base-T for copper connections over standard Ethernet cables and 1000Base-X for fiber connections through the SFP slot. This dual-media support provides flexibility for connecting to different network infrastructures and enables fiber uplinks for longer distance connections.
Can this switch be mounted on a DIN rail or wall?
Yes, the CMICR-4PC is designed for both wall mounting and DIN rail mounting. The compact form factor and included mounting hardware allow installation in various environments, including industrial control panels where DIN rail is standard or office settings where wall mounting is preferred. This flexibility makes it suitable for space-constrained deployments.
