DC Power Supply Wiring Instructions
The following diagram shows wiring configurations for 48 VDC power
supplies:
Specifications
AC Chassis
Environmental:
Operating Temperature: 32° - 122° F (0° - 50° C)
Storage Temperature: 20° - 160° F (-20° - 70° C)
Humidity: 5 - 95% (non-condensing)
Electrical:
AC Input Load: 100-240 VAC ±10%, 50/60 Hz, 1A max.
Dimensions:
1 Slot:
1.55”H x 4.75”L x 7.31”D (3.94cm H x 12.07cm L x 18.57cm D)
Heat Generation:
51 BTU/hr. maximum
Forcing the Duplex Mode
The LAN Extenders’ Ethernet port can be manually configured for either
Half- or Full-Duplex operation. Before manually setting the duplex mode,
disable Auto-Negotiation (Set Dip Switch 1 to
OFF
.)
• Configure the Ethernet port for Full-Duplex by setting Dip Switch 6
to the
ON
position (Default).
• Configure the Ethernet port for Half-Duplex by setting Dip Switch 6
to the
OFF
position.
Forcing the Speed
The LAN Extenders’ Ethernet port can be manually configured for 10 or
100 Mbps operation. Before manually setting the speed, disable Auto-
Negotiation (Set Dip Switch 1 to the
OFF
position.)
• Configure the Ethernet port for 10 Mbps operation by setting
Dip Switch 5 to the
OFF
position.
• Configure the Ethernet port for 100 Mbps operation by setting
Dip Switch 5 to the
ON
position.
Flow Control
Flow Control is used to throttle the END device to avoid dropping pack-
ets during network congestion. Full-Duplex Flow Control will Advertise
ONLY in Full-Duplex Mode. Full-Duplex Flow Control functions ONLY if
the link partner (end device) also has Flow Control. Half-Duplex Flow
Control DOES NOT Advertise. Configure the Ethernet port on the LAN
Extenders for Flow Control by setting Dip Switch 3 to the
ON
position.
Link Fault Propagate
Link Fault Propagate (LFP) is a troubleshooting feature. When LFP is
enabled and the Host CO unit detects that the Remote CPE does not have
a copper link, LFP will disable the Host’s copper transmitter. Configure CO
LAN Extenders for LFP by setting Dip Switch 9 to the
ON
position. Do not
enable LFP on CPE LAN Extenders.
N O T E
The chasis is protected against mis-wiring. If mis-wired,
the chassis will not function.
