NBX IP Telephony Platforms 29 Table 8 V5000 Connectors and LEDs (continued) 6 COM1 DB-9 connector that provides an RS-232 (DCE) TTY terminal connection for access to system CLI commands and status messages. For information on how to connect to the NBX system using the Console connector, see "Connecting a Computer to a Console Port" on page 196. 7 COM2 Reserved for future use. 8 Ethernet 1 10/100 switched Ethernet connection redundant uplink port. Use Ethernet 1 port to connect to the LAN. Ethernet 2 port is normally inactive and becomes active only port 1 experiences a link failure. Both ports show a positive link status even though only one port at a time is active. Typically, you would connect each port to a different switch and subnet. 9 Network Three LEDs for each of the 2 Ethernet ports indicate port Status LEDs status: ■ LNK - Solid on indicates link; Off indicates no link. ■ 10 - Blinking indicates network activity at 10 MB; Solid on indicates heavy network activity. ■ 100 - Blinking indicates network activity at 10 MB; Solid on indicates heavy network activity. 10 Ethernet 2 A fail-over port that is active only if the Ethernet 1 port experiences a link failure. The Ethernet ports can operate at 10 Mbps and 100 Mbps; they automatically sense the speed of your LAN. Typically, you would connect the Ethernet 1 and Ethernet 2 ports to a different switches and subnets. 11 VOL This adjusting screw controls the volume of Music-On-Hold. 12 MOH Mini-jack (mono or stereo) that accepts Music-On-Hold audio (maximum 2V peak to peak) from the line output of a CD player, tape player, or other music source. 13 Paging This RJ-11 connector provides an audio output or a dry contact switch connection for use with a public address system. 14 Ext. Alert Reserved for future use. 15 System Status S1, S2, S3 and PWR provide a visual indication of system LEDs status. See Table 9, next.

COM1
DB-9 connector that provides an RS-232 (DCE) TTY terminal
connection for access to system CLI commands and status
messages. For information on how to connect to the
NBX system using the Console connector, see
“

COM2
Reserved for future use.
8
Ethernet 1
10/100 switched Ethernet connection redundant uplink port.
Use Ethernet 1 port to connect to the LAN. Ethernet 2 port is
normally inactive and becomes active only port 1 experiences
a link failure. Both ports show a positive link status even
though only one port at a time is active. Typically, you would
connect each port to a different switch and subnet.
9
Network
Status LEDs
Three LEDs for each of the 2 Ethernet ports indicate port
status:
■
LNK — Solid on indicates link; Off indicates no link.
■
10 — Blinking indicates network activity at 10 MB;
Solid on indicates heavy network activity.
■
100 — Blinking indicates network activity at 10 MB;
Solid on indicates heavy network activity.
10
Ethernet 2
A fail-over port that is active only if the Ethernet 1 port
experiences a link failure. The Ethernet ports can operate at
10 Mbps and 100 Mbps; they automatically sense the speed
of your LAN. Typically, you would connect the Ethernet 1 and
Ethernet 2 ports to a different switches and subnets.
11
VOL
This adjusting screw controls the volume of Music-On-Hold.
12
MOH
Mini-jack (mono or stereo) that accepts Music-On-Hold audio
(maximum 2V peak to peak) from the line output of a CD
player, tape player, or other music source.
13
Paging
This RJ-11 connector provides an audio output or a dry
contact switch connection for use with a public address
system.
