Rear Panel Connectors, Indicators, & Power Switch
ZonicBook/618 Rear Panel
The ZonicBook/618E Rear Panel includes an LED legend in the upper left corner. Wording of the legend
is duplicated below. The rear panel also includes connectors, LED indicators, and a power switch.
LED Legend: Applies to the three LEDs located between the Ethernet Port and the Expansion Port.
LED ON OFF
L LINK NO LINK
T 100 BASE-T 10 BASE-T
D FULL-DUPLEX MODE HALF-DUPLEX MODE
ETHERNET: The 10/100BaseT Ethernet port can connect to the Ethernet port of the host PC, or to an
Ethernet network. Either of two Ethernet patch cables may be used to make the connection. CA-242 is a
1.5 foot cable. CA-242-7 is a 7-foot cable. Note that the Ethernet connector has two built in LEDs that
indicate traffic flow. These are discussed with the three other Ethernet-related LEDs. Note that the
Ethernet cable length must be <10m in order for the system to be CE Compliant.
LEDs: There are 5 ETHERNET Status LEDS. Two rectangular LEDs (Tx and Rx) are built into the
frame of the Ethernet jack. The other three LEDs, located just to the right of the jack, are round and are
labeled L, T, and D.
Tx – “ON” indicates traffic is being transmitted (see figure at right).
Rx – “ON” indicates that the port is receiving traffic.
L (Link) “ON” indicates a link exists. “OFF” indicates no link.
T (BaseT) “ON” indicates 100BaseTx, “OFF” indicates 10BaseT.
D (Duplex) “ON” indicates full duplex, which allows simultaneous
two-way data traffic. “OFF” indicates half-duplex, which only allows
one-way data traffic at any given time.
Tx and Rx LEDs
EXPANSION PORT: The Expansion Port is reserved for future use.
MAC Address Label: The Media Access Control (MAC) label
shows the device serial number in barcode and base 10 formats. It
also shows the Ethernet address (MAC Address) which is derived
from the serial number in hexadecimal. If prompted to enter a
serial number in software, use the base 10 number. Conversion to a
hexadecimal number for use in addressing will be automatic.
Note: If your network administrator asks you for a MAC number or MAC Address, provide the
hexadecimal number that is located at the bottom of the label.
SYNC: The two “synchronization ports” are reserved for future use.
