DEMO MANUAL DC3160A
QUICK START PROCEDURE
DC3160A-KIT Operation in Auto Mode
DC3160A-KIT includes the DC3159A daughter card and
DC3017A motherboard. This kit allows for evaluating the
LTC9101-1/LTC9102/LTC9103 chipset configured as a
either a 20-port or 24-port, 4-pair PSE Endpoint. Refer
to Table 1 for the differences between DC3160A-A-KIT
and DC3160A-B-KIT.
Follow the procedure below and refer to Figure 1 through
Figure 3, and Table 2 through Table 9 for proper equip-
ment setup and default configuration. This default setup
will automatically power all valid PDs at all power classes.
1. On the DC3017A motherboard, set AUTO jumper (JP16)
to HI to enable autonomous operation.
2. On the DC3017A motherboard, set 4PVALID jumper
(JP14) to LO to only power IEEE 802.3 compliant PDs
that present a valid detection signature on both Alterna-
tive A and Alternative B pairsets. 4PVALID is ignored
while the system is configured as a 2-pair PSE.
3. On the DC3017A motherboard, set the jumper
PWRMD-1 (JP1) for the maximum power level, PM6.
4. On the DC3017A motherboard, set the address switches
AD2 and AD3 (SW5) to LO for the default 20h base
2
I C address.
5. On the DC3017A motherboard, set the CFG0 (JP20), CFG1
(JP21), and CFG2 (JP22) jumpers to HI to set CFG[2:0]
logically to 111b for 4-pair operation at all ports.

6. Align pin 1 of the 16-pin male connector P1 on the
DC3159A daughter card with pin 1 of the 16-pin female
connector J11 on the DC3017A motherboard as shown
in Figure 2. The six male connectors and six female
sockets should match. Keyed pins in J16 and J12 as-
sist with the alignment shown in Figure 3. Carefully
push the daughter card straight down until the male
and female connectors are flush with each other.
7. Connect a supply to the DC3017A motherboard with the
positive rail to POS INPUT (+) and negative rail to NEG
INPUT (–) as shown in Figure 3. Use a power supply
capable of sourcing the maximum sourced power for
all ports to be tested. Ramp the supply up to within
the recommended voltage range specified in Table 2.
NOTE: Banana jacks J8 and J10 should only be used for
up to 15A of supply current. Use the lugnut terminals J7
and J9 with the provided Panduit S4-14R lugs for supply
currents of up to 50A; enough for 24 ports at maximum
power.
8. Connect up to twenty-four IEEE 802.3af, 802.3at, or
802.3bt PDs to the motherboard's RJ45 connectors
J3 and J4, as shown in Figure 3.
NOTE: RJ45 ports 15, 16, 20 and 21 on J3 are blocked on
the DC3017A-A motherboard in the DC3160A-B-KIT. See
the section on Port Output for more information.
