

LEDIndicators

PWR1 Green Power Module 1 active

PWR2 Green Power Module 2 active

OP1 Green Off = off

On = optical link is good

blinking = working port

OP2 Green Off = off or disabled

On = optical link is good

Blinking = working port

Channels Dual Color One LED for each channel (1-8) or (1-16)

Green = E1/T1 Signal Present

Off = Out of Service

Amber = E1/T1 Loss of Signal

Amber (blinking) = channel in loopback mode

ALM Red Indicates an alarm has occurred, includes E1 or T1 BPV, signal

loss, LAN link down, or fiber sync slip.

RDI Red Remote Defect Indicator, indicates an alarm has occurred in

the remote multiplexer, includes E1, T1, LAN and fiber signal

loss.

SYS Green Indicates the system is normal

SNMP Green If SNMP option is installed, indicates the agent is active by

blinking once per second.

Phone Green Indicates the order wire is in use.

E1 Green For an E1/T1 multiplexer, On if configured as E1-RJ45 (120

ohm), OFF for T1-RJ-45 (100 ohm), Blinking for E1-BNC (75

ohm)

LNK (LAN) Green 4 LEDs, one for each LAN port

On = LAN link established

Flashing = link with traffic

Off = no LAN link or port disabled

100M (LAN) Dual Color 4 LEDs, one for each LAN port

Amber On = The LAN speed is 1000M (FMUX1600, 800 only)

Green On = The LAN speed is 100M

Off = If link is present, the LAN speed is 10M

Standalone/RackMountFiberOpticalMultiplexer.

2.2 Site Preparation

Install the Fiber Multiplexer within reach of an easily accessible grounded AC outlet. The outlet should be

capableoffurnishing100to240VAC(18to60VDCforDCsupply).Allowatleast10cm(4inch)clearanceattherear

andfrontoftheFiber Multiplexer forsignallinesandinterfacecables.

2.3 Mechanical Assembly

The Fiber Multiplexer is designed for rack mount installation and only requires 1U space (1 3/4") in a

standard EIA 19 inch rack. It is highly recommended that the unit be placed in a rack. The Fiber Multiplexer is

delivered completely assembled, with the exception of the rack mount adapter brackets. No provision is made fo

r

boltingtheFiber Multiplexer toatabletop.

ESDprecautionswhenhandlingtheSFPmodules.Fiberopticcomponentsand cablesarevery sensitive to dirt,dust

and mishandling, especially in high‐speed networks. Dirty or mistreated fiber may cause errors and an unwa

nted

degradation of signal quality. Remove the dust caps on SFP and patch cable connectors only when ready to plug in

opticalcables.

WhenchoosingSFPopticalmodules,theSFPmustbeabletosupporttherequireddatarate.FortheFMUX800
