WLC 7.6.100 and PI 2.0

Today we are running software 7.5.102.0 on our 5508 controllers and software 1.3 on PI.
We now considering upgrade to 7.6.100 on the controllers and 2.0 on PI. In the release notes for 7.6.100 it says: "Cisco Prime Infrastructure 1.4.1 is needed to manage Cisco WLC software Release 7.6.100.0", but i guess that they mean 1.4.1 or higher?

HI,
As per this link 7.4.110.0 is the last support for 5508 WLC.
http://www.cisco.com/en/US/docs/net_mgmt/prime/infrastructure/2.0/release/notes/cpi_rn.html
confirmed through TAC that PI 2.1 is the only release that will support 7.6 WLC code.
It would be good to wait for 2.1 and then upgrade.

WLC 7.6.100 traps

Hello Guyz,
I have recently upgraded to WLC 7.6.100 on WLC5508 and i am receiving the following trap messages often.
Cause=Indicates that while the radio state should be updated on controller, no reset should be reported. Status:NA
Any idea what would be the cause?
thanks in advance.

Might be an issue with the code... that version wasn't great. There is a new version which ifxes some major bugs.... v7.6.110.0.... this is what you should upgrade to.

I just bought my macbook pro and it's charged up to 100% and is still plugged in but now shows the battery at 98%. How is this possible when it's plugged in to the charger and the green light is on?

I just bought my macbook pro and it's charged up to 100% and is still plugged in but now shows the battery at 98%. How is this possible when it's plugged in to the charger and the green light is on?

The system regularly lets the battery drop to about 95% when on the charger, then recharges to 100%. This lets the batery exercise "just a little" all of the time and saves the recharge curcuits from overuse.
Regualr occurence for me.
Also ... you need to let your battery work at least once per month. Let it run down to 40%, but not less if you can at all avoid it. Running thr battery fully dead will shorten the battery life significantly.

My iPhone 5s with iOS 7.1 become very hot when charged almost reach 100% and will shut down itself.

My iPhone 5s with iOS 7.1 become very hot when charged almost reach 100 % and will shut down itself. Then I need to off the power and let it cool down first before I can on the phone back. Please help me to solve this problem. Thanks.

Hi Limfromsi,
It is normal to an extent for the iPhone to get warm during charging. If your iPhone is currently in a case, you may want to try charging it without one and see if the issue occurs, as the design of the iPhone uses the exterior of the device as a cooling surface. For more information about iPhones and temperature, you may find the following article helpful:

If you continue to have issues with your iPhone in the default config (no case, using the included original cable and power adapter), you may want to have your phone evaluated for service. The following page may be of use:

After updating to latest Firefox - when I click on google taskbar my CPU usage goes to 100% and stays there... and computer is really slow. No other search engine show the 100% usage like Google. There was NOT a problem with older versions of Firefox...?

My computer got really slow after updating to latest version of Firefox. I checked all processes and I was testing the system. THe CPU usage goes between 2 and 70 percent staying around 25% on average, when I check my e-mail. As soon as I click on Google taskbar (without even typing in anything) the CPU usage jumps to 100% and STAYS at 100 %, and computer extremely slow.

Premiere Pro CS6: GTX 660 ti ($300) vs. GTS 450 ($100) and other thoughts on upgrading HW

I've been wanting to make some major upgrades to my hardware, but it just doesn't seem worth it yet...even after almost 4 years. I ultimately decided to "rent" a new video card and run some tests. Here is some background info on my upgrade though process and some results comparing the video card performance.
Disclaimer: I'm not a hardware expert, but I'm not completely clueless (I think). Your input/insight is welcome.
My system (purchasd 2/2009)
i7 920
GTS 450 (1GB RAM)
12 GB 1333 RAM
Samsung SATA II 128 GB SSD (OS/apps)
5x 1TB 7200 RPM drives in RAID 0 (with accompany slow/cheaper 2TB backup drives)
Some upgrade options I am considering
Sandy Bridge 3930 - but it's $560 w/o cooling and would require a new, more expensive motherboard, new ram, cooling, etc.
Ivy Bridge 3770, but I keep reading that that an overclocked 920 isn't that much different in perf (in fairness mine isn't oc'd). I did find a MB that would work for only $90. So I could make this upgrade for just under $400 (RAM would stay the same).
Wait for Haswell, but i could be another 9 months and it's supposed to only give maybe a 10% perf gain over IB. It's more focused on mobile - less power, integrated graphics, etc.
High-end Xeons are totally off the table. $/buck is waaaay too low.
Video card and benchmark reviews/problems
So I thought I'd first try getting a new video card. I see conflicting benchmarks. This site (the one that provides the CUDA.exe hack) notices very little difference between most GTX cards in perf for their benchmarks. The PPMB5 site shows significant differences between say the GTX 680 and lower end cards. But are these really accurate?
The GTX 680 is almost $500, so I opted for the 660 ti at $300 to see if I could get a noticable perf gain. It seemed like the best $/buck card and wouldn't require me to get a new power supply.
Another reason I wanted to do my own tests: None of the benchmarks I've seen actually mention the type of footage used. I care about footage from the Canon MKII-III, or similar footage. I definitely do not care about things like exporting to MPEG 2.
I did some very unscientific benchmarks, but they were real world for me. First my "problem" areas.
Performance problem areas
#1 - Time-lapses consisting of 1080 (height) JPEGs and 2160 (height) JPEGs don't always play smoothly (larger 2160s almost never do). I read adding more VRAM might help. The 660ti has 2x the RAM as my current video card.
#2 - Split screen sequences (up to 9 clips simultaneously) don't play smoothly.
#3 - Scenes where I speed up a clip to 1000x don't always play smoothly. (Although upgrading from CS5 to 6 actually seems to have solved this issue, I couldn't get it to repro any longer).
#4 - Export to h.264 could be faster. I do this a lot, but mostly because it's how I sometimes make proxies because of problems around #1-2 (works fine - used to use CineForm but it always crashed Premiere and these work for my needs). This is typically my final export as well for posting on sites like Vimeo.
#5 - Timeline rendering could be faster, although I don't do this a lot and if I do it's simple, not a bunch of crazy effects. E.g. use unsharp mask. This is pretty low pri for me though because I think timeline rendering is a bad idea. Once you do it, if you even move the clip you have to render again.
Some simple bottleneck analysis first:
Disk queue length sometimes is just over 1 on 1 disk in my RAID array during TL playback. Might slow things down slightly. Not an issue during export.
Processor never seems to get pegged in any case.
RAM is never maxed out, but it starts to go to Premiere limits (10 GB that I've set) after playing through several time-lapses (I'm just now noticing this). Choppiness starts well before RAM is even near that on some clips.
Tests/results:
NOTE: I do run the 660ti in a PCIe 2 x16 slot. Let me know if you think it would even matter to run in a PCIe 3.0 slot. My MB doesn't have one.
#1 Time-lapse smoothness - didn't improve with the 660. Moving the 1080 size JPEG TLs to my SSD did help some problem TLs play smoothly however.
#2 Split screen. Did a test with a 9-clip-at-the-same-time sequence. No improvement with the 660ti.
#3 Clips speed up 1000x - could not repro the problem now that I run CS 6 vs. 5 on either card.
#4 - Export to H.264 1080p @23.9x fps.
Export 5:30 clip of 5D MKIII footage + H.264 proxies:
GTS 450 - 9:14
660 Ti - 8:30
Export 1.5 minute clip of large time-lapses (JPEGs that are 2160 high):
GTS 450 - 9:35
660 Ti - 7:00
Export a 2 minute clip of just MKIII footage
GTS 450 - 2:45
660 Ti - 2:45
#5 Timeline render with simple image correction effect
Timeline render short 5D MKIII clip with unsharp mask applied:
GTS 450 - 1:10
660 Ti - 1:19
Conclusion:
The 660ti ($300) showed marginal improvements in exporting h.264 against my GTS 450 ($100) and did not address my other issues. Definitely not worth it for the type of work I do.
Moving my time-lapse JPEGs to an SSD helps play the 1080p versions back smoothly. The 2160p larger versions still lag. Maybe more RAM would help? They still start off choppy and then acquire more and more RAM, so not sure here. Maybe faster 1600 RAM? I don't know, I doubt it. I may have to just use 1080 versions or make proxies.
I don't see a pegged CPU much if at all, so upgrading to an Ivy Bridge 3770 doesn't seem like it'll help much if at all.
I did end up buying 2x256 GB SATA III SSDs (only $169 each) that I'll run current projects off of, or at least time-lapse sequences (RAID 0). My motherboard doesn't have an SATA III slots, however, so I won't see the full power of these, but not sure I'll need it. Again I'm not seeing a clear disk issue either from the perf monitoring.
I suspect many of these problems are still with the software and how it takes advantage of my hardware, but I'd love more insight.
Generally I make things work and I don't have any really painful bottlenecks, but I'm always up for perf improvements/doing things faster. It does look like I won't see any major breakthroughs, however by spending $400-$1000 bucks on HW upgrades.
Thoughts?

Thanks for the resonpose Harm. Inline.
Harm Millaard wrote: SYSTEM: It is an older system, about the same I had in the form of 'Harm's Beast', although I have a much beefier disk setup, more memory and OC'ed to 3.7 GHz, in combination with a GTX 480. Not much you can do about this system, apart from upgrading memory to 24 GB but the major drawback is that those investments will not carry over to a new system, at least not easily. [Luke] From your description of your system it sounds like 4 things could indeed be upgraded and carried over to a new system. 1) OC the processor (e.g. purchase a generic water cooler for ~$100), 2) Improve the Disk setup, 3) Upgrade the video card, 4) Add more/faster RAM.
I've seen in some benchmarks that an OC'd 920 is not so dissimilar to an OC'd 3770K. The latter is faster, but it isn't a huge difference. The larger question still remains - will any/all of these upgrades yield large performance gains and solve all/a higher percentage of my problems? Or do I have a decent sweet spot of a system and should wait for the software (e.g. MPE evolution in CS7-8) to catch up and take better advantage of what I have? Like I said from doing some rudimentary performance monitoring, I'm not seeing a pegged CPU (just a brief spike here/there), I'm not seeing disk transfer at capacity (although 1 disk has a slightly > 1 queue length at times), I'm not seeing in all cases over-utilization of memory, etc. (except higher RAM usage is seen albeit staggered for large JPEG time-lapse sequences, but I see choppiness well before RAM usage gets to 10 GB).
VIDEO: You correctly point out that the GTX 680 shows in the MPE graph on the PPBM5 website much better results than other cards. But keep in mind that most 680's are used in new systems, often with the latest CPU's and fast memory. I'm convinced that a 680 is not noticeably faster than a 580, because they have the same memory bandwidth, but it looks that way because they are often accompanied by hexa core i7-39xx CPU's with large amounts of memory. [Luke] Good point - potentially further evidence that the video card doesn't make a big difference? At least not enought to justify 5x the cost (e.g. $500 680 vs. $100 450). This would be consistnet with what Studio 1 Productions has seen. The GTS 450 has a memory bandwidth of 86 GB/s, the 660 Ti has 144.2 GB/s, so the latter is significantly faster as you have shown in some of your tests. [Luke] The only test I would characterize closer to having a significant increase using the 660 would be exporting large JPEG time-lapses to H.264, where it was a good 27% faster. The rest seemed more marginal or did not change. TESTING: You don't mention to what format you exported and with what resolution and framerate. Hardware MPE will come into play when you have rescaling, frame blending, blurring and stuff like that occurring. If you export to the same frame size and frame rate as your source and no blurring occurs, then exporting is purely a CPU matter and the video card has no impact at all. [Luke] See above - H.264, 1080p @23.9x fps. General remarks: I personally consider your 5 disk raid0 setup as pretty risky. You have multiplied the risk of losing all data by a factor 5!. You have no redundancy at all. Even though it is fast, I expect your sustained transfer rates are less than 450 MB/s and when using a 9 clip split screen, it may be too slow with the limited memory and the old CPU you have. You have effectively one single volume for video related editing (apart from the OS disk) and while that makes for easy administration, it still entails the drawbacks of the half-duplex connection of SATA. It might be better to add a couple of HDD's in raid0 for media cache, previews and exports to avoid that limitation. You can always carry those to a new system. [Luke] Yes there is a higher level of risk, but with backups every 30 minutes during project work I yield cheap/easy perf gains for the cost of--at most--30 minutes of work. I've lost no work in the last 4 years, 1 drive failed once while on vacation and I replaced it easily. Anyway backup/data integrity is a different issue separate from performance which I'd like to focus on in this context.
I get ~420MB/s read with this array (mostly older, blue WD drives and Deskstars). I'm running out of space, so I just ordered 3 x 2 TB WD black drives to replace this with, expecting probably a similar transfer rate. Again though I'm not necessarily seeing disk being a bottleneck in perf mon aside from one disk who's queue length sometimes goes over 1, so we'll see if the newer black drives help.
I have ordered 2x256 SATA III SSDs to put min my time-lapses on as having them on my current primary SSD seemed to help in some cases.
Sorry to be so harsh. [Luke] No worries, harsh is OK but I'm still not seeing a clear solution to some of my issues and I'm still not convinced a new system - short of a top-of-the-line SB or Xeon system (both of which are very $$) will be worth the upgrade. When 5 years had passed between my current system and my 2004 system, I feel like the upgrades were much more significant especially for bang/$.

Viewing on external monitor with ADVC-100 and s video

I am trying to view my canvas on a external monitor. I have a canopus ADVC-100 and i am using the firewire input and the s video as the output in the back. When I try to set it up and i select view all frames, but when i go to the video output menu it says my firewire device is missing. Any hints or tips on what i am doing wrong. I am using the s-video because the monitor only has a components input available, the RCA's are already occupied.

Is the ADVC powered? When you connect firewire to the back of the unit, it gets powered by that connector, but the firewire jack on the front is only 4-pin and doesn't support power.
If you have a 6-pin to 6-pin firewire cable, try connecting it to the back of the ADVC110 and then the front of the box should light up, indicating power.
I'm having a similar issue. I can print to tape via the Canopus box, but I want to be able to drive a monitor with it just so I can have an NTSC monitor while I'm editing. I can't seem to make it work. Any ideas?

My britness on my iphone 5 was on 100 % and I turn my screen off and after ten min I turn it back on and the screen was on 0% while the britness line on settings was on 100% is it an IOS 6 bug or is my iphone borking???

I've seen that happen sometimes. For me, pressing the lock button to lock it, and then pressing the home button to get to the lock screen reverts it back. If that doesn't work, just move your brightness slider lower and then higher again.

GPIB ENET/100 and PCMCIA GPIB+ pictures

Hi,
We don't have any other pictures available than the ones on the online datasheets. Is there something specific you want to know about a feature of this hardware?
I not, that maybe someone on the forum, that has the hardware available, can take a digital picture of it.

Illaas,
I tried the manual method. I was able to set the music/video to manual and then restarted the entire system. After restart, I re-attached the ipod touch to the computer. The sync automatically ran for everything that wasn't set to manual and it completed without a problem. I then reset the music/video to automatically sync and restarted the entire coputer/ipod set again. This time when I re-attached the ipod, EVERYTHING synced and there were no problems reported. I've never had to do this before, but I will keep it in mind if something like this happens again. Thank you for pointing me to the manual sync.

A simple percentage? How does one add a percentage to a number? If I have 100 and I want to add 15% and get a total, what formula would I use?

You can do something like this:

this means in the cell D2 type the following "=B2*(1+C2/100)"... leave out the double quotes

i downloaded the new 7 update on my ipad. it now will not charge to 100% and loses power even when not in use. any solutions ??

Try a reset: Simultaneously hold down the Home and On buttons until the device shuts down. Ignore the off slider if it appears. Once shut down is complete, if it doesn't restart on it own, turn the device back on using the On button. In some cases it also helps to double click the Home button and close all apps BEFORE doing the reset.
Then plug it in and let it fully charge.

New number of posts bug(?) + question; no #100, and total # of posts vary

New number of posts bug(?) + question; no number 100, and total number of posts vary
Intrigued by Tuttle's new attempt to join Niel's old habit to keep his own total number of posts count, I went and start counting my posts since the New Discussions. Because I saved my latest Old Discussions Post-and-Points info, I can see what are the previously-still-online ones (the pre- 14-Nov-2005 01:31 GMT ones), and I know exactly what was my "real" total number of posts before 14-Nov-2005 (2446).
My New Discussions posts number however, is quite uncertain.
Firstly, when I use the "My Posts" link on the right, then clicking on and on on the "Next" link,
my "Viewing 91-100 of 586 -- Pages" shows 91-99 instead of 91-100
(= should show 10 posts, shows 9 posts)
then I go on clicking Next Next Next, and I see the same missing counts happen elsewhere:
my posts number 100, 259, 260, 370, 390, 520, 558, 559, 560, 578, 579, and 580 are missing too.
Note that I wouldn't bother doing all this, and I would have thought it's just very old posts that are automatically deleted like in the Old Discussions,
BUT,
the problem is that when I choose to see all my posts together on the same page
(by using the start=0&range=600 suffix in the URL)
I get a total number of posts that is different (570).
A third way to quickly see all posts without having to load too big page
(using the start=0&range=300 suffix in the URL then only one "Next" click)
shows yet another, different again, number of total posts (573).
And my "official" total number of posts is (586).
Dear HOSTS,
- If this can be used as a bug report to fix a counting problem, glad to help.
- If there is no bug, I have two(+) questions then:
1) Was my post number 100 deleted?
(should be around 27-Nov-2005 18:00 GMT)
Also:
I thought the Total Posts number that we see in "My Public Profile" or under the avatar in each post (586), was only the number of posts still online.
- if it is the case, then there are no automatically deleted old posts anymore?
- if old posts are automatically deleted like before, this number should vary?
- if it doesn't vary (it just grows by one per new post), AND at the same time old posts are actually automatically deleted,
it has to show the "real" total number of posts then,
(as it is now, a total starting from the Old-Discussions-still-online-posts, it makes no sense),
that is,
the total posts in the New Discussions PLUS the total posts since first registration in the Old Discussions.
So,
2) What does it show exactly?
Thanks again for all the great work!
Axl
220? 221?

Thank you Andreas,
Your confirmation about the "post #100 bug" does help.
"As for your other missing posts - I guess Tuttle's assessment that they might be deleted is probably right..."
Yes, that makes sense and that's what I'm trying to figure in my OP, but then,
after I posted my "#221/2667 post" (11-Dec-2005 21:51 GMT), my originally missing #
259, 260, 370, 390, 520, 558, 559, 560, 578, 579, and 580
should have become
260, 261, 371, 391, 521, 559, 560, 561, 579, 580, and 581
right? (forget the #100: this one we know for sure it's a bug)
Or if the software counts them from the first (now that would have been a good start) instead of starting from the most recent,
they should become
258, 259, 369, 389, 519, 557, 558, 559, 577, 578, and 579
Well, that's not what happened. Now the missing # are
259, 260, 370, 390, 400, 520, 559, 560, 570, 579, and 580
(in addition to the same #100) (#558 and 578 not missing anymore).
As you can see, there is no logic:
It doesn't work as a simple numerotation of StillOnlinePosts, no matter the order
(otherwise there would simply be a straight count from 1 to 575 (=587-12).
It looks indeed like it shows which old posts are being automatically deleted. That the numbers are quite the same would simply show that the old posts dates were so close, of course they are deleted (six months later) almost at the same time,
BUT,
if it was the case, there would never be LESS deleted posts between two StillOnlinePosts, like it happens for example between my StillOnlinePosts #557 and #561.
Please note: of course I stick to the same method to make all my counts. Not manually modifying the URL, just using the default Next-Next-Next- clicking...
Modifying URL would add yet more differences in the differences!..
Dear Hosts,
Too bad it doesn't help looking yourself at my "My Posts", as everything changes each time I'm adding a reply somewhere.
Perhaps a good way to troubleshoot this would be to start from a very simple basis:
--> "name" the posts with a number, starting from the oldest.
This way, for example my "#1" post (11-Dec-2005 21:51 GMT in this thread) would be named "221" in the New Discussions, or "2667" if you start from my Registration date.
At the moment, it is very difficult to figure what fault comes from the "#100 post bug" and what fault comes from another possible counting bug...
Then the New Discussions "fluctuating" refreshing delay too, possibly messes the counts...
Thanks!

Can we use a 5508 WLC in Hong Kong and join 3602 APs in Vietnam to it? Any regulatory contraints?

Hi friends,
I am looking for some wisdom here!
Just wondering if I can use a 5508 WLC in Hong Kong and join 3602 APs in Vietnam to it?
Any regulatory contsraints / guidelines that would prohibit from doing so?
- Regards,
Tarun.

You have two differnt regulations... here is a link:

You need to make sure you are not breaking any rules and it is best to have an AP that is specific to that country. Also if you add multiple country codes on a WLC, the AP's will only be able to use the most common channels and TX power setting allowed on both. Here is a link explaining that.
