Before Installing An Expansion Chassis; Connecting The Chassis-B And Chassis-E Together - NEC ux5000 Hardware Manual

Chapter 1 - Installing the Chassis
The Expansion chassis uses an expansion bracket which attaches to the right side of the Controlling/Base
chassis.
When multiple chassis (combined Chassis-B and Chassis-E or a Chassis-A) are to be connected, an
Expansion chassis kit is required to connect the chassis together (using the EXIFU blade).
●
Note: When wall-mounting a UX5000 system, make sure the wall can support the weight of the
chassis (20 lbs per system chassis). It is recommended that plywood first be installed on the wall where
the chassis will be positioned, allowing for secure anchoring.
