16 input modules can be installed per headend unit. Hot swap
technology is used in the headend, meaning that modules can be
inserted/removed/moved when the headend is in operation.
Each input module is identified through the use of a specifically
coloured label. The label also indicates the module type‟s name and
associated item number. The remainder of the label is used for noting
post-installation module information.
Another label containing a barcode and serial number is located on the
underside of the input module.
