Call of Duty: Black Ops Cold War Zombies - Firebase Z - Crystal Cannister #2 Mini Lockdown in Jungle Defense
Prerequisites: Generators turned on, Serum, Essence Traps, Floppy Disc, Aethermeter & Shovel

If you head to the "Jungle Defense" area middle section where zombies spawn in you will see an interaction to Dig. Dig up the crystal cannister to start a Mini Lockdown that lasts for about 1 minute on solo. Just stay in the highlighted area for a few minutes and survive the waves of dogs and special zombies. After the time is up pick up your 2nd crystal.
