2. Interfaces
2.1. V.35
The V.35 interface is equipped with DB-25 connector. A V.35 cable
terminated with 34-pin male (DTE) Winchester connector should be
connected here, so the router could be connected to a DCE device, like a
V.35 modem.
2.2. Ethernet
The Ethernet interface is used to connect the router to the Local
®
Area Network. In case of Tahoe 1801 router it is a single RJ-45
connector with four LEDs:
¡
LNK - LAN Link, signals a proper connection to the LAN
¡
COL - Collision, signals an attempt to transmit to the LAN while
another device also sends data
¡
LRX - LAN Receive, flashes, when data is received from the LAN
¡
LTX - LAN Transmit, flashes, when data is transmitted to the LAN
A router should be connected to an Ethernet switch or a hub using
a straight patch-cord or to a PC, another router or an uplink port in a
switch using a crossed-over one. After connecting a LED named “LAN
Link” should be lit.
®
In case of Tahoe 1808 router an 8-port switch is available
instead of a single Ethernet interface. Each switch port has three LEDs
associated to it:
¡
10/100Mbps - when lit, signals a 100Mbps connection
¡
LINK/ACTIVITY - when lit signals a proper connection to the
other device, flashes while transmitting or receiving data
¡
DUPLEX/COLLISION - when lit signals a full-duplex
connection, flashes when a collision occurs in a half-duplex
connection
The switch can be managed through a telnet or console
connection. It supports VLAN tagging and automatically detects a
crossed-over cable (so-called MDIX function).
2.3. Serial console
The RS-232 serial console is used for router management. It has a
DB9/M connector and works as a DTE, i.e. a null-modem cable should be
used to connect it to a PC. Three lines (bolded) are sufficient. Terminal
