Here's an "easter egg" from Star Trek: First Contact. As everyone probably knows, the AE-35 unit was the electronic component in 2001: A Space Odyssey which HAL 9000 reports is faulty. If it burns out, the Discovery will no longer be able to control its antenna, and it will lose contact with Earth. An astronaut attempts to replace it, and is killed by HAL.
Here in First Contact, the Borg are trying to use the Enterprise-E's deflector dish to contact their compatriots. Capt. Picard, Mr. Worf, and Ensign Hawk take a spacewalk to disconnect the dish. To do so, they have to turn off the "maglocks" that hold the disk to the Enterprise.
The unit is clearly labeled "SUBSYS ID= MAGLOCK AE35".
