Zorluk: OrtaNetwork Hardware Devices

A field technician is installing a new IP-based security camera in a remote warehouse corner. The camera requires Power over Ethernet (PoE) to operate, but the existing network switch supplying the Ethernet drop does not support PoE functionality. Budget constraints prevent replacing or adding a new PoE-capable switch. Which network hardware device should the technician install inline between the switch port and the camera to provide the necessary electrical power over the Category 6 cabling?

  1. PoE injectorCevap
  2. B
    Layer 3 router
  3. C
    DHCP server appliance
  4. D
    Media converter

Cevap

The correct device is a PoE injector, which injects electrical power onto a standard Ethernet cable run from a non-PoE network switch.
A PoE injector (also called a midspan device) is placed inline between a non-PoE switch port and a PoE-enabled device like an IP camera. It accepts a data connection from the switch, adds electrical power using its own power source, and transmits both data and power over the Ethernet cable to the remote endpoint.

Adım Adım Çözüm

1
Identify the primary requirement and constraint
The target end device (IP camera) requires PoE power, but the existing infrastructure switch cannot supply power.
Determining the missing capability dictates which dedicated single-function hardware device is needed.
2
Evaluate hardware solutions for power injection
A PoE injector (midspan device) connects inline between a standard switch port and the powered device to inject power onto the data lines.
This avoids replacing existing non-PoE switch infrastructure while fulfilling power requirements.
