The Energy Routers appear in Ice Hive on Arcterra in Metroid Prime Hunters. There are 6 in total, organized by letters A-F. All but one are shielded by force fields. Scanning the unblocked router will send an electrical surge that will disable the force fields one by one and expose the rest of the routers to scanning. Samus must be quick. Scanning each will restore power to it, until two Barbed War Wasp hives are aggravated into attacking.
