In the DC power configuration, the router contains two DC power supplies (see Figure 15
on page 31), located in the right rear of the chassis in slots
A single DC power supply provides sufficient power for a fully configured router.
Each power supply (AC or DC) is hot-insertable and hot-removable.
NOTE: To maintain proper cooling and prevent thermal shutdown of the
operating power supply unit, each power supply slot must contain either a
power supply or a blank panel. If you remove a power supply, you must install
a replacement power supply or a blank panel shortly after the removal.
