MultiVOIP Front Panel LEDs
LED Types. The MultiVOIPs have two types of LEDs on their front panels:
(1) general operation LED indicators (for power, booting, and
ethernet functions), and
(2) channel operation LED indicators that describe the data traffic and performance in each VOIP data
channel.
Active LEDs. On the MVPFXS units, there are four WAN LEDs and twenty-four channel-operation LEDs.
However, on the MVPFXS-8, only the left eight sets of channel-operation LEDs are functional. On the
MVPFXS-16, only the left sixteen sets of channel-operation LEDs are functional. All of the channel-
operation LEDs are functional on the MVPFXS-24 unit.

LED NAME DESCRIPTION
General Operation LEDs (one set on each MultiVOIP model)
Power Indicates presence of power.
Boot
After power up, the Boot LED will be on briefly while the MultiVOIP is booting. It lights
whenever the MultiVOIP is booting or downloading a setup configuration data set.
Ethernet
FDX. LED indicates whether Ethernet connection is half-duplex or full-duplex
(FDX) and, in half-duplex mode, indicates occurrence of data collisions. LED is on
constantly for full-duplex mode; LED is off constantly for half-duplex mode.
When operating in half-duplex mode, the LED will flash during data collisions.
LNK. Link/Activity LED. This LED is lit if Ethernet connection has been made. It
is off when the link is down (i.e., when no Ethernet connection exists). While link
is up, this LED will flash off to indicate data activity.
SPD. Data speed indicator. When lit, data rate is 100 Mbps. When not lit,
data rate is 10 Mbps.
COL. Collision indicator. Lit when data collision is detected on Ethernet
network.
Channel-Operation LEDs
1, 2, 3, ... 24
There is one LED for each voip channel (channels 1-8 for MVPFXS-8; channels 1-16
for MVPFXS-16; channels 1-24 for MVPFXS-24). The indicator for any channel is lit
when there is call activity on that voip channel. The LED is ON when the device
attached to the channel is off hook.
