3Com Router Module Guide 4.14.3 Panel and Interface LEDs Chapter 4 The following figure illustrates the ROUTER 1-PORT OC3 POS FIC panel: Figure 4-47 ROUTER 1-PORT OC3 POS FIC panel The following table describes the LEDs on the ROUTER 1-PORT OC3 POS FIC panel. Table 4-32 LEDs on the ROUTER 1-PORT OC3 POS FIC panel LED Description LINK OFF means no link is present; ON means a link is present. OFF means no data is being transmitted or received; blinking means data is being ACT received or/and transmitted. 4.14.4 Interface Optical Fiber Like the FICCPOS, the ROUTER 1-PORT OC3 POS FIC uses optical fibers with LC-type connectors (see Error! Reference source not found.). 4.14.5 Connecting the Interface Optical Fiber Step 1: Insert the SFP card into its corresponding slot. Step 2: Locate the Rx and Tx fiber-optic interfaces on the interface card. Use two fibers to connect the ROUTER 1-PORT OC3 POS FIC to another device: Rx to Tx and Tx to Rx. Step 3: Power on the device and check the LINK LED on the ROUTER 1-PORT OC3 POS FIC panel: ON means the Rx link is present and OFF means the opposite. In the latter case, check the line status. Warning: Because invisible laser radiation may be emitted from the aperture of an optical port when no fiber is connected or the dust cap is removed, do not stare into the open aperture. Replace the dust cap when no fiber is connected to the optical port. 4-50

Description
LINK
OFF means no link is present; ON means a link is present.
ACT
OFF means no data is being transmitted or received; blinking means data is being
received or/and transmitted.

Interface Optical Fiber
Like the FICCPOS, the ROUTER 1-PORT OC3 POS FIC uses optical fibers with
LC-type connectors (see

).
4.14.5
Connecting the Interface Optical Fiber
Step 1: Insert the SFP card into its corresponding slot.
Step 2: Locate the Rx and Tx fiber-optic interfaces on the interface card. Use two
fibers to connect the ROUTER 1-PORT OC3 POS FIC to another device: Rx to Tx and
Tx to Rx.
Step 3: Power on the device and check the LINK LED on the ROUTER 1-PORT OC3
POS FIC panel: ON means the Rx link is present and OFF means the opposite. In the
latter case, check the line status.
Warning:
Because invisible laser radiation may be emitted from the aperture of an optical port when no fiber is
connected or the dust cap is removed, do not stare into the open aperture.
Replace the dust cap when no fiber is connected to the optical port.
