8 PA-5EFL Ethernet 10BASE-FL Port Adapter Installation and Configuration

What Is the 5EFL Port Adapter?

Table 4 lists multimode optical-fiber parameters.

Table 4 Multimode Optical-Fiber Parameters

What Is the 5EFL Port Adapter?

The 5EFL port adapter provides up to five IEEE 802.3 Ethernet 10BASE-FL interfaces. (See

Figure 1.) Each Ethernet 10BASE-FL interface allows a maximum bandwidth of 10 Mbps, for a

maximum aggregate bandwidth of 50 Mbps, half-duplex. Each 10BASE-FL interface uses two

multimode (ST) receptacles for receive (RX) and transmit (TX). All five ports run at wire speed.

Port Adapter Locations on the VIP2 and in the Cisco 7200 Series Routers

This section provides information about where you can install the 5EFL port adapter on the VIP2

and in the Cisco 7200 series routers.

Note Port adapters have handles that allow for easy installation and removal; however, they are

occasionally not shown in this publication to highlight port adapter faceplate detail.

Figure 2 shows a VIP2-15 or VIP2-40 with two installed port adapters. Figure 3 shows a VIP2-50

with two installed port adapters. With the VIP2 oriented as shown, the left port adapter is in port

adapter slot 0, and the right port adapter is in port adapter slot 1.
