Fiber and Cabling
Step 8 When you are ready to attach the network interface fiber-optic cable, remove the protective plug from
the GBIC and save the plug for future use.
Procedure: Crimp Replacement CAT-5 Cables
You can crimp your own CAT-5 cables for use with the ONS 15454 SDH. Use a cross-over cable when
connecting an ONS 15454 SDH to a hub, LAN modem, or switch, and use a straight-through cable when
connecting an ONS 15454 SDH to a router or workstation. Use CAT 5 cable RJ-45 T-568B, Color Code
(100 Mbps), and a crimping tool.
