Optional Fiber Ports - ZyXEL Communications NXC5200 User Manual

Chapter 1 Introduction
An auto-crossover (auto-MDI/MDI-X) port automatically works with a straight-
through or crossover Ethernet cable.
Default Ethernet Settings
The factory default negotiation settings for the Ethernet ports on the NXC are:
• Speed: Auto
• Duplex: Auto
• Flow control: On (you cannot configure the flow control setting, but the NXC can
negotiate with the peer and turn it off if needed)

1.3.2 Optional Fiber Ports

Fiber connectivity requires a few additional considerations when you deploy the
NXC with that in mind.
Figure 5 Fiber Connection Example
AP
First, you must have a fiber-based Core Switch (CS) upstream of the NXC. It
connects to one of the available fiber ports in the Fiber port module loaded into
the NXC's expansion bay. Next, an additional fiber connection is established
between the NXC and a downstream fiber-based Power over Ethernet (PoE)
capable of converting Fiber-to-Ethernet data packets (such as the ZyXEL MC1000-
SFP-FP). Finally, you connect your AP to the edge switch using an Ethernet cable.
