This analysis confirms a previously reported X-ray cavity at ∼ 36 kpc and reports a newly detected X-ray cavity at ∼ 42 kpc north-west of the X-ray peak. This analysis also identifies the presence of a cold front at ∼ 72 kpc and a sloshing arm, probably due to the minor merger. The surface brightness reveals a sharp edge at the location of the cold front and exhibits discontinuity in the temperature profile. The broken power law analysis confirms its association with the cold front. The mechanical power deposited in the form of X-ray cavities ∼ 6.0 ×10^44 erg s−1 is capable enough to heat the ICM and correlates well with the 1.4 GHz radio power, further compensating to offset radiative losses. Considering the morphological properties of the extended radio emission at 325 MHz, we classify RXCJ1558.3-1410 as a host to a radio mini halo.
