For a router equipped with DC-input PEMs:
– Green LED labeled INPUT OK—When the power module is fully seated in its bay and is
receiving source power within the required range, this LED should be on. It indicates that DC
power source is present and is within specified limits. The power supply fan should also be on.
Green LED labeled OUTPUT OK—PEM is operating normally in a powered-on condition.
–
Amber LED labeled MISWIRE—Should be off. When it is on, it indicates that the input is wired
