A field technician is deploying a network management appliance inside an industrial facility with significant electromagnetic interference (EMI) from heavy motorized equipment. The deployment requires establishing a direct connection to a legacy switch console port using an RS-232 serial interface, as well as running a 10Gbps Ethernet network trunk line over a distance of 85 meters () across the factory floor. Which TWO of the following cabling standards and physical connector types must the technician select to meet these requirements?
- DB-9 connector for the serial console interfaceCevap
- STP Category 6a cable for the Ethernet network trunk lineCevap
- CRJ-11 connector for the serial console interface
- DUTP Category 6 cable for the Ethernet network trunk line
Cevap
The technician should select the DB-9 connector for the serial console connection and STP Category 6a cabling for the 10Gbps Ethernet trunk line.
Connecting to a legacy RS-232 serial console port requires a DB-9 connector. Running 10Gbps Ethernet over 85 meters in an environment with high electromagnetic interference requires Category 6a STP cabling, which supports 10Gbps up to 100 meters and includes foil shielding against motor noise.
