Installation Overview
Serial-Copper Cables
Serial-copper cables are lighter than ECL cables.
Fiber-Optic Cables
The NonStop S-series servers support two types of fiber-optic cables: multimode fiber
(MMF) and single-mode fiber (SMF).
Which cables you use depends on the fiber-optic plug-in cards (F-PICs) installed in the
ports to which the cables connect.
Do not interchange SMF and MMF cables even though their connectors are similar.
SMF cables operate correctly only with SMF PICs, and MMF cables operate correctly
only with MMF PICs. MMF cables are often orange, and SMF cables are often yellow.
You can distinguish the cables by the part numbers printed on them.
For most systems that use fiber-optic cables, MMF cables are recommended. SMF
cables are used primarily with the ServerNet Cluster product to connect MSEBs to
ServerNet cluster switches. For the ServerNet Cluster application, you must install
NNA PICs in connector 6 of each MSEB you plan to use.
Fiber-optic cables allow enclosures to be placed further apart than ECL or
serial-copper cables.

Caution. You can bend or break two small retainer pins inside the associated PIC receptacle.
When you disconnect a serial-copper cable connector from a serial-copper PIC, fully and firmly
depress the tab on the cable connector before pulling out the cable connector.
