Caution
To avoid damaging the Ethernet interface, turn off the printer before making any Ethernet connections.
Ethernet connections and indicators
-
RCV indicator (green); blinks while the interface is receiving.
-
XMT indicator (yellow); blinks while the interface is transmitting.
-
Twisted pair (10BaseT) connector.
Ethernet cables
100BaseTx requires Category 5 (100-Ohm UTP) cabling.
To fully comply with EMI (electro-magnetic interference) specifications, the use of shielded or screened cables may be required. "Shielded" describes IBM-defined cables used with the DB-9 connector. "Screened" describes cables that are electrically similar to Category 4 UTP (Unshielded Twisted Pair), but with an added shield or screen.
Do not use "silver satin" telephone extension cables for 10BaseT networks, either as drop cords or as patch cables in the wiring closet. (Silver satin cables are flat, usually silver or gray, with 28-gauge stranded or tinsel conductors.) Do not use shielded twisted pair cable intended for IBM Token Ring networks or voice-grade (level 1 or 2) unshielded twisted pair cables.
These cables do not meet the requirements for 10BaseT and will lead to unreliable operation.
