Safety Notes
22
Damage to blade/Backplane or System Components
Bent pins or loose components can cause damage to the blade, the backplane, or other system
components.
Therefore, carefully inspect the blade and the backplane for both pin and component integrity
before installation.
Emerson and our suppliers take significant steps to ensure there are no bent pins on the
backplane or connector damage to the boards prior to leaving the factory. Bent pins caused by
improper installation or by inserting boards with damaged connectors could void the ECC
warranty for the backplane or boards.
Data loss
Removing the blade with the blue LED still blinking causes data loss.
Wait until the blue LED is permanently illuminated, before removing the blade.
Cabling and Connectors
Blade Damage
The RJ-45 connector(s) on the face plate are twisted-pair Ethernet (TPE) or E1/T1/J1 interfaces.
Connecting an E1/T1/J1 line to an Ethernet connector may damage the product.
z
Make sure that TPE connectors near your working area are clearly marked as network
connectors.
z
Verify that the length of an electric cable connected to a TPE bushing does not exceed 100
meters.
z
Make sure the TPE bushing of the system is connected only to safety extra low voltage
circuits (SELV circuits).
If in doubt, ask your system administrator.
