2.5.1
Fiber-Optic Cable Installation
After the electrical and digital interface cables have been wired according to sections 2.4
and 2.5 , insert the SFP module into the SFP cage (Z1) and attach the fiber-optic cable to it (see
Figure 3 for location of Z1). The SFP module slides into the RFI Cage label side up. There will
be a slight click when it locks into place. After the SFP module is installed the fiber-optic cable
can be installed. The cable must be an LC type connection. The cable should be oriented with the
thumb tab at the top. When completely inserted the tabs will click into place.
2.6 Initial Checkout Procedure
F271XA telephone modems contain no power on/off switch. Once power is connected, the
Modem will go through its power-up sequence. When the System LED (see Table 2) is lit the
Modem is ready for use. Before beginning system operation check the following to verify proper
installation:
1.
Verify that the power plug is seated fully into the Modem or the Modem is seated fully in the
rack-mount enclosure (HF-20A or VMX20).
2.
Verify that the fiber cable is connected on each end.
3.
Verify that the Link LED (see Table 2) is lit when the fiber-optic cable is connected and the
units, both local and remote, are powered.
If a malfunction is detected during the initial checkout procedure, refer to Section 5 for
information on isolating the malfunction in the unit.
