To remove a DEM-16:
1. Using a properly terminated, antistatic wrist strap, loosen the fastener at the top of the module
(this fastener secures the module to the chassis).
2. When the BUSY LED is not lit (not green), grasp the module handle and carefully remove the
DEM-16 from the chassis.

NOTICE
Equipment Damage Risk: Use adapters when connecting any 6-pin plug to an 8-pin jack. Although a
6-pin plug will fit into an 8-pin jack, the plastic on the 6-pin plug housing will damage pins 1 and 8 on the
8-pin jack. Not using adapters will increase the likelihood of failure (to pins 1 and 8 in the 8-pin jack)
should that jack need to be used with an 8-pin plug in the future. Various adapter types are available
based on how you choose to connect to the patch panel.
