After the end of the Run 3 data taking, the Large Hadron Collider will be upgraded to reach instantaneous luminosities of up to $7.5 \times 10^{34} \,\mathrm{cm^{-2}s^{-1}}$, allowing the CMS experiment to collect up to $4000 \,\mathrm{fb^{-1}}$ integrated luminosity, roughly nine times the amount of data that will have been collected by the end of Run 3. To fully exploit the physics potential of the High-Luminosity LHC, the entire CMS detector will undergo substantial upgrades. The Phase-2 upgrade of the CMS inner tracker aims to build a new tracking detector with higher granularity, longer trigger latency, improved radiation hardness, and extended coverage up to pseudorapidities of $\vert\eta\vert=4.0$. To meet the powering requirements while keeping the material budget low despite a greatly increased number of channels, the Phase-2 inner tracker will implement serial powering of pixel modules. In the TEPX sub-detector, the longest serial power chain will include 11 modules. In this contribution, CMS read-out chip version 1 quad modules will be characterized, with a focus on the comparison between the performance standalone or in a serial power chain.
