The V-Station 4G, V-Flex 4G devices both support Power over Ethernet (PoE), using
their RJ-45 Ethernet interface. When these devices are to be powered over Ethernet, an
IEEE 802.3af compliant Active Midspan Injector must be used. Such an injector is not
supplied with L-1 Identity Solutions products. An example of a suitable PoE injector is
Model No. AT-61 01 G from Allied Telesis Inc. (http://www.alliedtelesis.com).
Any such device should carry at least one of the certifications shown below and should
be FCC listed.
Figure 4-10 Certification Marks
Figure 4-11 Power Over Ethernet Connection
Specifications for suitable PoE Injectors for 4G Indoor devices are as follows:
9 Input voltage: 90-264 VAC, 60 Hz
9 Input current: 0.4A @ 100 VAC
9 Output voltage: -48 VDC
9 Output current: 0.32A
9 Power: 15.36 W
For Power over Ethernet, RJ-45 pin numbers 4, 5 are considered VB1 (+) positive DC
supply, and pin numbers 7, 8 are VB2(-) DC return.
