== Pin 1 identification ==
All components whose pins needs to be marked in electronic equipment (because the component has several pins, like any chip/IC or connectors) always has a mark in pin 1... sometimes this mark is not visible because is "printed" under the component itself (so only visible before soldering the component to the board)... this seems to be the case in some of the connectors in PS3 power/eject boards, so the identification of pin 1 can be confusing


As example... HSW-001 board has a "copper point" marked close to the connector... but this point is the ground pin of the capacitor placed below (the blue text in the first photo is wrong because this point is not related with the connector). So there is no way to identify pin1 by looking at HSW-001 board... the solution is to look at the connector in the other side of the ribbon cable (in other words... in the main motherboard)
== PS3 2000 series Power Eject boards, enabling contour leds talk ==

This is a temporal section to discuss the simplest/easyer/safest/better way to make this mod, and the posible variations

The photos at the right are a first sketch to discuss how to improve the photos or the circuit, and are intented to replace the photos of this section in front page: http://www.ps3devwiki.com/wiki/Power_Eject_boards#Enabling_the_.22contour_leds.22_in_DSW-001_and_HSW-001_power_eject_boards

==Non retail Switch boards==
*Light rays bouncing photo (this goes first because is easy to discuss)
[[SW-13]], used in [[COOKIE-13]]
**I could not find a better one where the first bouncing surface is more visible, this first surface is the most important but also the curve for the next bounces, is good to cover this with a mirror sticker (by sticking it in the case, this way the glue layer is at the other side)... no photo of this sticker
<gallery>
**Is barelly visible the light ray starts in verticall, and after the first bounce is in horizontal... arrows didnt helped

The cutted trace in pin1 is just because the board was designed to be controlled this way, even if is not in retail models is possible that exist a prototype with it, also is needed to be 100% sure the pin goes nowhere (is posible the trace goes to an internal layer of the motherboard not visible in the surface and emerge again in a syscon pin)
 
The transistor base pin goes in-line with the other unpopulated transistor base pin, both does the same function at the same time, each of this transistors is in chargue of 2 leds. This transistors are "isolating" the subcircuit of the 4 leds
 
The unpopulated resistors values are dependant of the leds added, so no need to add the values to the drawing
