Zorluk: KolayUtilizing Hardware Testers and Packet Analyzers

A network technician is installing a new VoIP phone at a user's desk. The technician must trace an unlabeled UTP cable run from the office wall jack back to its corresponding port on the patch panel in the equipment closet. Once identified, the technician must also confirm that the switch port is actively supplying electrical power over the ethernet wiring to power the phone. Which TWO of the following tools should the technician use to accomplish these tasks? (Select TWO.)

  1. Tone generator and probeCevap
  2. PoE testerCevap
  3. C
    Optical Time-Domain Reflectometer (OTDR)
  4. D
    Packet analyzer

Cevap

The correct tools to select are the tone generator and probe (to trace the physical cable path from the desk wall jack to the patch panel) and the PoE tester (to detect and verify electric power delivery on the twisted-pair switch port).
Tracing an unlabelled copper run requires emitting an electrical tone via a tone generator at the wall jack and listening for that signal with an inductive probe at the patch panel. Confirming that power is being delivered to the VoIP phone requires a PoE tester to measure active DC power on the Ethernet port.

Adım Adım Çözüm

1
Identify the physical cable tracing tool.
Select the tone generator and probe, which places a tone signal on unshielded twisted-pair (UTP) copper wire and detects it audibly at the patch panel.
Tracing physical copper cable runs across walls and ceilings requires an inductive tone probe.
2
Identify the power verification tool.
Select the PoE tester, which verifies voltage standards (such as 802.3af/at/bt) supplied by the switch port.
VoIP phones rely on Power over Ethernet (PoE) supplied across the copper Ethernet conductors.
