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. OntheDC3017Amotherboard,setAUTOjumper(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

thatpresentavaliddetectionsignatureonbothAlterna-

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. OntheDC3017Amotherboard,settheaddressswitches

AD2 and AD3 (SW5) to LO for the default 20h base

5. OntheDC3017Amotherboard,settheCFG0(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

connectorJ11ontheDC3017Amotherboardasshown

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. ConnectasupplytotheDC3017Amotherboardwiththe

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.
