RJ-45 Connector
System Damage
RJ-45 connectors on blades are either twisted-pair Ethernet (TPE) or E1/T1/J1 network
interfaces. Connecting an E1/T1/J1 line to an Ethernet connector may damage your system.
Make sure that TPE connectors near your working area are clearly marked as network
connectors.
Verify that the length of an electric Ethernet cable connected to a RJ-45 TPE bushing does
not exceed 100 m.
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.
For more information, see the documentation of the respective blade.
Laser

If a label with the words CLASS 1 LASER PRODUCT is affixed to the back of your system, the unit
is equipped with a laser device. These devices contain a laser diode that produces invisible laser
radiation harmful to the eyes.
Performing adjustments or procedures other than those specified in this manual may result in
hazardous radiation exposure. Do not look into the optical lens at any time.
Environment
Environmental Damage
