Green FUD

CLAIM:  The Sun Ray has no on/off switch, thus wastes power.

They've got us there, at least with the Sun Ray not having an on/off switch.  Since administrators don't need to touch Sun Rays our customers have told us there is no need for one.  Sure there is the occasional complaint, but nothing that merits a change.  Power cycling the Sun Ray can be controlled via the keyboard.  We'd be interested in hearing scenario that would require an administrator to require that Sun Ray to be powered off.  What this really sounds like is the competition taking their own instructions on how to fix a broken thin client by installing a base OS image from a flash drive and trying to apply it to a Sun Ray.

The “green” argument doesn't hold water either since a majority if not all of the competitive devices and Sun Rays use external power supplies that continue to draw power whether the device is on or off.  Only solution is to unplug the power supply or does what Sun does in our campus offices.  We have motion detectors that cut power to the whole room if it is unoccupied.  Even the best made external power supplies consume a couple of watts when nothing is connected.  But since it is Blog Action Day, I'll throw out an eco-friendly fact about Sun Ray.  The Sun Ray 2 draws roughly 4 watts and the 2FS draws about 8 (4.6 and 8.4 to be exact).  That's something the competition can't match.

The on/off switch is a legacy holdover from most thin client vendors PC heritage.  Besides being unnecessary, not having one also means one less thing that break which increases the MTBF and decreases cost (including warranty costs).
Comments:

Well in place of a power switch, How about a reset button on the unit?
With users who have non-sun keyboards it would be nice not to have to have them yank the power cord.

Steve,
You're running the latest FW right? Ctrl+Pause+a will do a reset for non-Sun keyboards.

Or you could just hook up a clapper inline.

Exceuse my ignorance but whats the difference between that and CTRL+ALT+BACKSPACE+BACKSPACE ThinGuy ?

ps. Would love a chat off-blog about Sun Ray connector for Windows and CAPS LOCK. Not sure what you can do.. got potentially tens of thousands of units riding on a solution..

How do you increase the volume when using Dell standard USB keyboard? When using a Sun keyboard the volume keys work fine just non-Sun we are having difficulty with. Also we find the SunRay 270 keyboard doesn't respond after its been idle for a few minutes and we need to unplug from the USB port and back in and then it works.

Tony, your key combo just kills the Xserver, does not "power cycle" the device.

Emerich,

See URL in my first comment above. If running 4.0 FW, Ctrl+pause+right arrow = louder, left = softer, down arrow = mute.

Hi Craig.
My company has developed an RDP plugin that extends its audio capabilities and I beleive you may be interested to use it in Sun Ray Connector for Windows. Can we discuss that? By email?

FYI... the LCD monitor wastes more power and needs to be energy compliant for shut down... any comments on how this is done with the SunRay?

Posted by Dave on October 18, 2007 at 04:29 AM PDT #

Dave,
Yes, LCD monitors consumes power. This is a factor with or without a Sun Ray. More so for other TC's and definitely more with a PC attached. Sun Ray 2 and 2FS will also tell the attached monitor to sleep. Typically LCD's in sleep mode draw the same power as they do when they are "off", unless of course you unplug them from the wall.

We have a requirement to force our monitors into sleep mode. One environment consists of 1G's and 2FS's running on SRSS 3.x software. This version does not seem to send a signal to the monitor to go into sleep mode (when the Sun monitors goes amber the our Fluke meter drops to almost a zero draw), but the 4.x environment does? What controls this and how can we enforce it on 3.x? -Thank you!

Looks like xset dpms options will do the trick...thx
