The T1600 router has either one nonredundant power supply or two redundant,
load-sharing power supplies. Each redundant power supply is hot-insertable and
hot-removable. When a redundant power supply is powered down or removed, the other
power supply automatically assumes the entire electrical load for the router. If you have
only one power supply, you must power off the system before removing the power supply.
