To reduce the possibility of ESD damage, shelves are equipped with grounding jacks to
enable personnel to ground themselves using wrist straps (Figure 1) while handling
circuit packs or working on a shelf. The jacks for connection of wrist straps are located
at the lower right-hand corner of each user panel and filter panel and at the rear of the
bay. These jacks are labeled. The wrist straps should be checked periodically with a
wrist strap tester to ensure that they are working properly.
