I have a Cisco 4506 chassis with (4) 48 port switch modules in it.  It is on a known good UPS, has redundant power supplies and everything.  About six weeks ago, the switch restarted itself for no known reason.  I couldn't find anything out of the ordinary ... it just came back online by the time I got to the switch room.

Today, It happened right at 3:00pm.  Reports that I got had some people losing power to the Cisco phones (PoE) and others claimed the phone didn't lose power but the display said ethernet connection lost.  The phones losing power were on switch module 3.

I went into the IOS and did a sh hardware and got this:

My question is, what else can I do from a troubleshooting standpoint?  Is it possible that just switch module 3 in the chassis lost power and the rest of the modules remained online?  I am having to accept end-user answers that some Cisco PoE phones lost power and some did not.…

Introducing the WatchGuard 420 Access Point
Introducing the WatchGuard 420 Access Point

WatchGuard's newest access point includes an 802.11ac Wave 2 chipset, providing the fastest speeds for VoIP, video and music streaming, and large data file transfers. Additionally, enjoy the benefits of strong security as the 3rd radio delivers dedicated WIPS protection!

We are looking to create a two node storage spaces direct hyper-converged cluster.  The storage would be a hybrid system with the following drives per server two NVME cache drive and two NVME drives for performance tier and 4 4TB SAS capacity drives.  The issue I am having is originally all of the NVME drives for cache and storage were supposed to be 1.6TB intel DC P3600 AIC cards. I was not able to get 8 matching drives due to price and availability. My back up is to get 4 2TB intel DC P3500 drives.  The 2TB DC P3500 drives are about 1GB/sec faster then the DC P3600's but the 3600's have much higher drives writes per day at 3.5 where the 3500's are only .3 drive writes per day.  I know that storage spaces direct wants to use the higher speed drives for Cache but I would loose the higher storage capacity and write endurance if the 3500's were selected as cache.  My question is since i don't have all the hardware I cant test this is there a way to manually select the slower but better write endurance DC P3600 drives as cache drives even know there are faster drives in the system?

Hi,

I have been instructed to restore some old backups from 2011 in an attempt to recover some data.

The Backup is of an Exchange 2010 Server taken using System Center Data Protection Manager 2007.

Sadly, the backup server in use at the time has been retired so the original hardware is unavailable.

Is it possible for me to build a new server, install DPM 2007 and somehow import/catalog the tape and recover the Exchange Server?

Thanks,

Andy

Hi,

I have a couple of 9260-8i raid HBA cards in different servers and would like to extend them beyond the default 8 drives.  The docs talk about an extender/expander hardware option but I've never gotten a clear idea of what it is, much less where to buy one.  

Thanks!

I have a lenovo a10-70f that only boots into recovery mode. I choose a command and I get the dead android logo with a triangle coming out of its stomach with a caption "no command"

My diagnostic is that the OS updated and screwed up, I've seen it similarly before with Google Play soft-bricking the entire tablet.

There is an option to update from from, does anyone know where I can get a copy of the original android image for this device? And where can I get a copy of the fastboot adb.sh file? I had it a while ago, and I lost it when my server mobo died.

Hi,
I am testing the deployment of BITLOCKER via GPO.
For the moment I want to just encrypt the fixed drives without using TPM
I have created a TEST OU and moved a single computer to it.
I have created a GPO and edited/activated the following
Computer Configuration>Administrative Templates>Windows Components>BITLOCKER encryption
I have activated the following
Control the use of BITLOCKER on fixed drives:ACTIVE
Configure the encryption on the hardware level on the fixed drives:ACTIVE
Select the recovery method for recovery of fixed drives using BITLOCKER: ACTIVE
The rest is not configured.
Please note that I have the GUI in french so the translation might not be exact.

I have applied the GPO to the TEST OU
run gpupdate /force on the only computed within the OU
Restarted the computer
The GPO does not seem to apply
manage-bde -status and the bitlocker mmc show the the bitlocker DISACTIVE

What am I doing wrong or what do i need to add?
Please help.
Lenovo ThinkPad with running Windows 10

Are there any compatibilty issues with OPAL drives?

When I boot up my Dell Latitude E5530 laptop, Windows Boot Manager screen appears after the Dell splash screen.   It says "Windows failed to start.   A recent hardware or software change might be the cause.   To fix the problem insert your windows  installation disc and restart your computer,etc."

File: \Boot\BCD
Status: 0xc000000f
Info: The boot Configuration Data for your PC is  missing or contains errors.

I do not have the original Windows disc.   If I download a disc image from Dell and put it on a USB stick, will this fix the problem?

I am currently setting up my home cinema room, where I want to control everything using my Echo Dot. I have set up Sky Q, Amazon Fire TV stick, Blu-ray player, etc.. to my  receiver, where each device has its own channel. All of that works perfectly.

As I`ve mentioned, I want my Echo Dot to control everything. Because of this I want the Output from the Echo Dot to come through the receiver, no matter what channel the receiver is on,  i. e. if I am using Sky Q I still want to be able to talk to and hear the Echo dots.

Does anyone have a solution I could apply?

Regards,
Cillian

I have a specific requirement, we have a large number of IT devices, they are already in an asset management software. The Devices run different software and are of different spec. Our project teams request the devices depending on the project they have e.g they may request 20 devices to be setup for a specific project. They will be returned after the project usually a few days later. I need a flexible tool that will us to track what project has what devices. It needs to be more flexible than most standard asset tracking in that both the project teams should be able to update and the IT teams. I can google! : ) I'm really looking for some personal experience on an enterprise level, thanks

I am having strange issue on a VM when I move it to Esxi 6.5. The server’s CPU reaches 100% at OS level.
It back to normal when I move it back to ESXi ver 6.0 host. The VM hardware ver is 7. Does ver 7 hardware supports in Esxi 6.5?

I am using windows 10.  Recently, I have lost the ability to cut and paste URL's.  I was originally using a Logitech wireless keyboard mouse combination and it worked perfectly.  All of a sudden...about 2-3 weeks ago it stopped working.  I swapped out the keyboard for a USB Kensington keyboard and still have the same problem.  I am wondering what I should be doing to solve this problem and also why did it happen in the first place.  Copy and paste is one of the most useful keyboard options in the computer world.  Keep in mind that I have tried deleting the keyboard in device manager and then rebooting the PC.  It does not solve the problem.
Does this mean I have to purchase a new keyboard???
Thanks for your assistance,

Good day to all! My name is Kelvin and I am experiencing difficulty with upgrading to IE 11.

Hello,

How much of a performance difference is there between Excel (2010) 32-bit vs Excel 64-bit when working with large files?

I occasionally work with large (200+ MB) .xlsm files which contain mostly text. When doing so it's not uncommon to experience sluggishness and/or get a pop-up saying Excel needs more resources. Also, I've noticed the Task Manager showing Excel to be using well over 1,000 MB of memory during those occurrences.

On the website listing Microsoft Excel specifications and limits, I found the following statement regarding memory usage for 32 vs 64-bit versions:

Maximum limits of memory storage and file size for Data Model workbooks

32-bit environment is subject to 2 gigabytes (GB) of virtual address space, shared by Excel, the workbook, and add-ins that run in the same process. A data model’s share of the address space might run up to 500 – 700 megabytes (MB), but could be less if other data models and add-ins are loaded.

64-bit environment imposes no hard limits on file size. Workbook size is limited only by available memory and system resources.

So with a fairly fast processor and 16 GB of memory, could I anticipate a significant improvement in performance and responsiveness?

Thanks

Let's say I got 2 mobile phones.

1. One mobile phone is logging into a Web System using web browser

If yes, how to do that?
