WS-C2960X-48FPS-L and SFP support Auto MDI/MDX or is crossover needed?

I have two WS-C2960X-48FPS-L running c2960x-universalk9-mz.150-2.EX5 and using two GLC-Ts in each switch etherchanneled together.
I put a straight-thru cable in and SW1 shows up/up and SW2 shows down/line protocol down. Do I need a cross-over cable?
Nothing is in err-disable. I did a shut and not shut on all interface and still one side is up/up and other side is down/down. Really odd.
Both sides have exact identical config.

Jason,
I remembered seeing a few posts regarding 2960X and a lot of SFP issues (HERE). The only solution was to downgrade to EX3 or EX4.
Ok, now here's the rub: EX4 was INITIALLY the solution to solve this issue regarding SFP/SFP+ issues with 2960X. The rub is even EX4 people started seeing MORE issues (other than SFP/SFP+). So the final "recommendation" is to go further down to EX3.
Personally, I wouldn't recommend anyone use 15.2(2)E. If you have to use 15.2(2)E then be careful. If you have 802.1x and PoE phones, AVOID 15.2(2)E or who-do-you-call (you won't be able to call someone. LITERALLY!)?

Cisco 4900M integrated X2 ports, CVR-X2-SFP10G and SFP-10G-SR

Hi,
We are going to order two(2) cisco 4900M switches for core and twelve (12) 2960S switches for access (4 stacks with 3 switches each), connected to the core with 10G MM optical paths (up to 300M each). In addition I have one gigabit half-card but it is not related to my questions here. Please see my attached diagram.
So my questions are:
1. Point 1.Can we use integrated eight X2 ports of every of the both 4900M switches as plugging into four of them four convertors CVR-X2-SFP10G and to plug on every of the convertors sfp tranceivers SFP-10G-SR - as it is described on the diagram, or I need for something more in addition to described? I found only some minimum soft releases to use as requirement to use these convertors and sfp tranceivers, but is there something additional I need?
Note:I'm asking that because Dynamic Conf Tool doesn't give me to do such configuration, actually these convertors and SFPs are missing there at all, but it sometimes happens with some products... In documentation it is described this should work (if I didn't pass something which is my main consern and why I'm asking here).
2.Point 3.If this shouldn't work, the other alternative (not described in my diagram) is to use X2-10GB-SR modules without any SFPs - just ot use SC connectors for the optical cables instead of LC. So my question in that case is will 10G links work between X2-10GB-SR at one side and SFP-10G-SR at the other side where I have 2960S switches and this is the only option? Is is expected to have some problems in that scenario?
Note:Actually if Point 1 is workable I prefer to use it instead of Point 2 because of minor price optimization when using SFPs with convertors in comparisson to X2-10GB-SR.
3. If the both variants are possible, which one is preffered and why, what advantages does it have (for example low latency of something else)?
Thank You in Advance
Asen

Just for your information, a fiber link does not care if one end of the fiber has an GBIC (SC-type connector) and the other end has a SFP (LC-type of connector); or any other transceiver footprint (X2, CFP, etc.).. The thing that is important is that each module is the same specification, and matches the fiber type and link length of the network (10GBASE-SX in this example).
Good luck.

WS-C2960X-48FPS-L vs WS-C2960X- 24TS-L

Hello All,
We are trying to setup datacenter for newly opened office and trying to find out the difference between
WS-C2960X- 24TS-L vs WS-C2960X-48FPS-L.
Could any of your throw light on how to choose between the two mentioned switches?

We are trying to setup datacenter for newly opened office and trying to find out the
difference between WS-C2960X-24TS-L vs WS-C2960X-48FPS-L.
I'd choose NEITHER for DC use.
WS-C2960X- 24TS-L is a 24-port, non-PoE and has four SFP (1 Gbps) ports.
WS-C2960X-48FPS-L is a 48-port, FULL PoE (750w PoE) and 4 SFP (1 Gbps) ports.
Neither switch models are designed for DC use. Catalyst switches are known for their shallow buffers. This means that if you have microburst of data to/from servers, the Catalyst switches' buffers will get full very quickly and start dropping data packets.
Cisco Nexus family of switches are more designed for DC use. Some people have also recommended the Catalyst 4500X as a cheaper alternative to Nexus.
Please don't forget to rate our useful posts.

Do the latest iMacs (new slim version) still support auto-switching from 220V to 110V?

do the latest iMacs (new slim version) still support auto-switching from 220V to 110V?

Yes. Apple power supplies work with voltages between 110 and 240 v.

When i try and open the auto cad Lt that i just downloaded i get this error The directory may be locked by another process or have been set Read Only. Directory: '/Users/hockaday' Please correct this problem and press OK to exit the application.

i get this error why i try and open the auto cad that i just downloaded
The directory may be locked by another process or have been set Read Only.
Directory: '/Users/hockaday'
Please correct this problem and press OK to exit the application.

I did install it in the admin account. Actually the computer has four accounts, one for my husband, where I installed it. One for me which also is set to admin, one is called TEST and has nothing in it and one is guest user.
I don't know how AutoCad is interfacing with the account. That is why I am not sure what to do about it. I read other threads in various places and some seemed to point to something having to do with having multiple users. The solutions were not clear. I was hoping someone else had this problem and could tell me what to do. I tried apple support but no help. I have not tried AutoCad yet as I assumed they wont help since this is a free educational version of their product.

8510 SFP support

Hi All
I found following spec in 8510 controller data sheet
Interfaces and Indicators
• 2 x 10 Gigabit Ethernet interfaces
• Small Form-Factor Pluggable (SFP) options (only Cisco SFPs supported): SFP-10G-SR
• LED indicators: Network Link, Diagnostics
• 1x Service Port: 10/100/1000 Mbps Ethernet (RJ-45)
However, I need Long Range SFP, i.e SFP-10G-LR
Would that be supported?

hehe. Me the same. I guess you also wanted to connect the controller to a physical diverse VSS or N7K or other system ? , now i am going to have it connected to two seperate N5K (no vpc) in Active/Standby mode.

[asr920] ASR-920-24SZ-M - SFP support

Hi, CSC:
Can someone please provide a full list of 1G SFP support for the asr920 for the 24 SFP ports (part number ASR-920-24SZ-M).
I'm particularly interested in the BX (bidirectional) SFP support. Data sheet and HW inst guide do not include this list.

hi frederik,
I apologize, but this forum is surrounded with experts in the IOS-XR area focusing on the ASR9xxx, CRS and NCS platforms.
The ASR920 is a different group running a different OS (IOS-XE), and I dont have the asnwer for you here. I tried to research it, but I can't find a good solid answer for you.
I would want to recommend to re-post this on the XE forums or ASR9xx (2 x's :) or open a tac case or consult with your AS or Sales engineers for this.
sorry...

IMAC's Top graphics card frustration - Cheap and no support for Adobe Mercury Playpack Engine GPU Acceleration?

If anyone has a solution for getting the Mecury Playpack Engine GPU acceleration to work with Premiere Pro CS6 on an iMAC 2011, please let me know. Like I wonder if you could Thunderbolt an External graphics card somehow? Or is an upgrade possible? Ahh...not worth the risk.
Please, if you have a solution for me, let me know. Otherwise I find it pretty frustrating that I purchased a top-end iMAC, fully maxed-out in every way possible, and that the iMac doesn't support Adobe Premiere's Mercury Playback Engine GPU acceleration. Also, an old USB 2.0 Hub and thus the built-in SD card reader is slow. If you have SD cards with 95MB/s Transfer, Read and Write speeds, the iMAC will only transfer at around 30MB/s if you're lucky. Technically 480Mbs which is around 50MB/s but I haven't seen those speeds.
I figured this could at least be circumvented with a Thunderbolt SD card reader or a Thunderbolt to USB 3.0 adapter but of course no such thing exists.
Well, nothing with a reasonable price tag. This all might seem trivial to some but when you're uploading 24 hours of HD video footage from a 128GB SDXC card, the speed makes a big difference.
And come on, no BluRay support? Ridiculous. I get the politics of why but still, just ridiculous. It would be nice to be able to burn a BluRay to watch in my home theater system. There are other methods but BluRay is convenient and great for backing up large Video Files. Unfortunately BluRay looks like it's not going to make it. Maybe cable distribution companies will increase their Internet upload speeds one day and I can just store everything in the cloud and watch full length movies(that I've created) on Vimeo.
Anyways, I went and took a look at the hardware Apple stuffed inside my fancy (3.4 Ghz i7, 16GB 1333 DDR3, 2GB AMD 6970M, 256 GB SSD Internal and 2TB 7200 Internal) machine and it appears to be pretty middle of the range stuff. It's an iMAC, not a Mac Pro so why am I griping? Because my 2009 PC(which I tricked out over the last two years) is faster and does support the Mercury Playback Engine. I spent $2100 total on this PC which includes all my upgrades. I spent around $3300 on the iMAC. I feel ripped off.
Yes, I do love my iMAC on multiple levels but had I known my dated 2009 PC would render video projects faster, I would have gone with a MAC Pro or just a new PC. It seems that Mac is moving completely away from making high-end computers for niche markets(video editing) and focusing on their tiny laptops, IPADS and IPhones for the masses. Obviously smart from a capitalistic perspective(at present at least) but very frustrating for some.
I was actually told to purchase a MAC for video editing. I've been a PC guy for 15 years. I went with the iMAC because I had read many good things about it(probably just Apple propaganda) and also the MAC PRO was to be discontinued. Also the MAC Pro would have been triple the cost for what didn't seem like a whole lot more.
It's one's thing to prepackage a computer with inferior hardware(the iMAC I have is fast for most things and more than enough for 99% of the population) but to not allow us to pop open the computer and make a quit upgrade to the machine is what really makes me feel like I'm using a computer built for Grannies. I mean there is a reason my mother loves iMacs and Iphones. Amazing that I was able to upgrade my memory from 4 to 16GB but I've heard Apple has even done away with that. I get why they do it. Apple Warranty, Apple Care issues, Profit and World Domination: Apple wants a monopoly on everything.
Was great to see Adobe bounce back after the whole Flash/HTML5 thing and knock Final Cut Pro off the face of the Earth for good. People are still buying it b/c of the brand name but Final Cut is done. David Fincher used Adobe's Workflow for everything when he made The Girl with The Dragon Tattoo. Hollywood is making the shift and the world will follow. The Adobe Workflow has finally come together and there is just no way Apple can compete with Adobe Creative Cloud and an Engine that can just swap from Premiere to After Effects to Prelude to SpeedGrade to Photoshop to Story with speed for $29 bucks a month(or $49 for some). Apple better start supporting Adobe's Mercury Engine or they may have a problem. And if you're using Final Cut X, you're severely handicapping yourself. Problem is that people don't want to take the time to learn Adobe's products(steep learning curve for sure) which is where Apple's Granny software, and perhaps computers, comes in to play. Arnold Schwarzenegger once said "Milk is for babies, Real Men Drink Beer". I'm beginning to think that "Mac's are for Grannies, Real Men Use Adobe and PCs".
The major problem with Apple is you're forced to use Apple. Not sure but history has proven that people don't like to be forced into anything. Autocracies don't work. These systems eventually topple, even in the corporate world.
Amazon.com, now that's the company to emulate. What an amazing machine!
I've read that Apple may even discontinue the iMAC after 2013. Who knows?

1) Graphcis Card - AMD Radeon HD 6970M 2048 MB (6990 would have been better or something from NVIDIA.
2) USB 2.0 Hub with only 480 Mb/sec
3) Seagate Baracude SATA I 7200 RPM drive with 3GB/s transfer rate and only a 32 GB Cach. It's ok. I would have expected at least a Western Digital Caviar Black 2 TB SATA III 7200 RPM 64 MB or the Velociraptor at 10,000RPM.
4)APPLE SSD TS256C Flash Drive. As you can see, it doesn't stack up so well against other SSD Drive.
Just average. http://www.harddrivebenchmark.net/hdd_lookup.phphdd=APPLE+SSD+TS256C

Whining and ranting about how iMacs can't do this or iMacs/orMacs can't do that is not going to get you a lot of help here.
Your "I love my MAC" is typical of the ever ubiquitous PC whiner.
If your video work needs were that computer intensive and critical , you should've done some online research and you should have budgeted for a Mac Pro.
Mac Pros are completely expandable and upgradeable unlike the iMac.
Mac Pros have much more faster and more CPU cores than the iMac line.
iMac line is limited to CPUs with 8 cores. The Mac Pros, I believe, are up to 16 core CPUs, now.
The Mac Pros can have their GPU upgraded and you even add/expand to use specialty audio/video cards.
Mac Pros are the defacto standard for real video work.
iMacs, even the high end model, is not really designed to do really heavy and intensive video work.
iMacs do do video creation and editing. Just not on the level that is needed from a more "Pro" computer.
It seems to me you are asking your iMac to do more than it was originally designed for, in terms of professional video editing.
You get a lot more out of a Mac Pro than an iMac for any real serious video, CGI or animation work.
You just didn't want to spend that much cash on one.
iMacs are not user upgradeable or friendly to user upgrades at all!!!
If you purchased a Mac Pro, you could've had that better, faster HD, better faster SSDs.
That said, I can offer no real help to but because of the nature of your post and the fact you just simply annoyed me, I feel some advice and explanations are in order
First off, you picked Adobe video editing software suite as your video creation software on the Mac. It's no secret to long-time video content creators on the Mac that Adobe products, especially those for video creation and editing are very user unfriendly on the Mac. Even though Macs are supported from Adobe, Adobe for a long time has treated the Mac and Mac users as second class citizens.
Before purchasing and installing Adobe Premiere, did you even check Adobe's site for the preferred system hardware and software requirements? Hmmm?
This is why you should KNOW what software you are going to be running on a computer first then research what computer make and model will run said software.
That's why Apple has its own apps like Aoerture, Logic and Final Cut.
Despite your ignorance in this matter, Final Cut Pro X is alive and doing well, thank you, and using this software on your iMac would kick Adobe Premier in the you know whats.
Final Cut Pro X is a complete video solution for and completely designed around the Mac.
Why are you using USB 2.0 connections for video work when you have a perfectly good FireWire 800 connection.
In case you are not aware, FireWire 800 is called so because it has a max throughput of 800 Mbps.
Your 2011 iMac can take up to 32 GBs of RAM. Not just 16 GBs.
This changed when the 2010 model iMacs came out.
Blu-ray? I believe you can buy external Blu-ray writers that work with Mac using said FW800 connection.
So you cite one movie and one videographer using Adobe Premier for your premise that Final Cut is dead in Hollywood?
Your argument that Apple locks you into everything in their world can be countered by saying Windows and Windows PCs lock you into the Windows world. What's your point?
Apple is not discontinuing their computers platforms any time soon.
All you are regurgitating is rumor. Probably from all of the PC crowd.
iMacs and professional desktop Macs are not going anywhere.
Currently, Apple is the only desktop/laptop computer maker that is still making a profit on their Macs and increasing their market share percentages for the last 5 years during which the PC market has continually slumped/dropped in its market share.

Passing a default value to the master block and do the auto query

Hi
My problem is i have a MD FORM to which i have to pass a default value and do an auto query so that when i run the form the form should open with this default value and do the query and get the details.
I tried many things like trying to set the value of the column using p_session.set_value and then calling the same form using wwa_app_module_link by using the value in the condition but every time unless i press the query button i did not get the values.
Now i don't know what to do.
My portal version is 3.0.7.6.2
Some body please help me
thanks
Sreedhar

I don't think this works for 3 parameters, but I know it will work for 1. Maybe you can do something with it.
1. Create a link to the destination component (YourProvider.YourLink)
2. Use the code below to use that link to pass the value of a form field to the destination component. 'FieldName' is the field on the destination component you want to query, and '_FieldName_cond' is the condition. This creates the destination URL.
3. wwa_app_module.set_target(l_url) will send you to the URL you generated.
l_url := PORTAL.wwv_user_utilities.get_url('YourProvider.YourLink', 'FieldName', v_YourParameterValue, '_FieldName_cond', '=');
portal.wwa_app_module.set_target(l_url);
I'm not the best at this, but this works for me in most cases.

Windows Vista 64 Bit and Button Support - Qosmio G30?

Windows Vista 64 Bit and Button Support?

Everybody claiming that Vista x64 (or Ultimate) can't be used with FN keys or Flash Cards is utterly wrong!
I have a Qosmio G30 running Vista x64 Ultimate, and have both FN keys, Toshiba Flash Cards and (partly) the hardware buttons at the top working.
After a lot of research, I found that Toshiba has released a 64-bit version of VAP called util_tvap_27581D. If you google it, you might discover it...
