Which Cisco access points are compatible with the AIR-RM1252A-E-K9=?
It is compatible with Cisco 1250 Series Access Points (e.g., AP1252) when installed in the designated radio expansion slot.
Is the AIR-RM1252A-E-K9= sold as a spare or complete access point?
It is sold strictly as a spare radio module; you must purchase the complete Cisco 1250 Series AP separately.
What is the maximum data throughput of this expansion module?
With 2×2 MIMO and 40 MHz channels, it delivers up to 300 Mbps aggregate throughput in the 5 GHz band.
Does the AIR-RM1252A-E-K9= support DFS for 5 GHz channels?
Yes, it supports Dynamic Frequency Selection (DFS) to automatically avoid radar interference in DFS-restricted bands.
How do I install the AIR-RM1252A-E-K9= into my access point?
Power off the AP, remove the cover, insert the module into the radio slot, secure with screws, reconnect antennas, then power on.
What antennas are recommended for use with the AIR-RM1252A-E-K9=?
Use Cisco-approved 5 GHz RP-TNC antennas such as AIR-ANT2459 or AIR-ANT2524 for optimal coverage.
Does the AIR-RM1252A-E-K9= support Cisco CleanAir technology?
No. CleanAir is available on integrated radios in later AP models; this spare module does not include CleanAir features.
What warranty covers the AIR-RM1252A-E-K9=?
Cisco provides a limited lifetime warranty when the module is installed in a supported access point under an active service contract.
