Protection

The M220nx module is protected by internal

solid state Polyswitches on the incoming

power and CMnet. These Polyswitches are

not replaceable and will reset themselves if

the condition that caused the fault returns to

normal.

To determine when a module was

manufactured, check the module status

report for the module in SuperVision. Refer to

the SuperVision User's Guide for more

information about the module status report.

A sticker on the back of the module also

shows the date the module was

manufactured. The first three characters on

the sticker indicate the type of module. The

next three characters show the year, month,

and week of manufacture. (The month digit is

in hexadecimal.)
