Recommended ESD Guidelines

Follow these guidelines when handling Grass Valley equipment:
• Only trained personnel that are connected to a grounding system should handle ESDS items.
• Do not open any protective bag, box, or special shipping packaging until you havebeen grounded.
NOTE: When a Personal Grounding strap is unavailable, as an absolute minimum, touch a metal object that is touching the oor (for example, a table, frame, or rack) to discharge any static energy before touching an ESDS item.
• Open the anti-static packaging by slitting any existing adhesive tapes. Do not tear the tapes off.
• Remove the ESDS item by holding it by its edges or by a metal panel.
• Do not touch the components of an ESDS item unless it is absolutely necessary to congure or repair the item.
• Keep the ESDS work area clear of all nonessential items such as coffee cups, pens, wrappers and personal items as these items can discharge static. If you need to set an ESDS item down, place it on an anti-static mat or on the anti-static packaging.

Sources of ESD and Risks

Safety Summaries
The following information identies possible sources of electrostatic discharge and can be used to help establish an ESD policy.
Personnel
One of the largest sources of static is personnel. The static can be released from a person’s clothing and shoes.
Environment
The environment includes the humidity and oors in a work area. The humidity level must be controlled and should not be allowed to uctuate over a broad range. Relative humidity (RH) is a major part in determining the level of static that is being generated. For example, at 10% - 20% RH a person walking across a carpeted oor can develop 35kV; yet when the relative humidity is increased to 70% - 80%, the person can only generate 1.5kV.
Static is generated as personnel move (or as equipment is moved) across a oor’s surface. Carpeted and waxed vinyl oors contribute to static build up.
Work Surfaces
Painted or vinyl-covered tables, chairs, conveyor belts, racks, carts, anodized surfaces, plexiglass covers, and shelving are all static generators.
Equipment
Any equipment commonly found in an ESD work area, such as solder guns, heat guns, blowers, etc., should be grounded.
Materials
Plastic work holders, foam, plastic tote boxes, pens, packaging containers and other items commonly found at workstations can generate static electricity.

About system messages

The following messages are displayed to indicate system status:
• Normal BIOS messages — These messagescan be observed on a locally connectedVGA monitor during normal startup processes.
• BIOS POST error messages — If there is a problem these messages are displayed on a locally connected VGA monitor. During the Power On Self Test (POST), the BIOS checks for problems and displays these messages.
• AppCenter startup messages — As AppCenter opens the system determines if health is adequate by checking critical subsystems. A dialog box is displayed that indicates progress and displays messages.
• Status bar and StatusPane messages — During normal operation AppCenter displays system status messages on the status bar. From the status bar you can open the StatusPane to see both current and previous messages. You can observe these messages in AppCenter on a locally connected VGA monitor or on a network connected control point PC.
• Storage Utility messages — While you are using Storage Utility, pop-up message boxes inform you of the current status of the storage system.

Your user name or password is not valid for this K2 Solo 3G system. Remember that the password is case sensitive.
• Click Ignore to view the AppCenter channels. If working remotely, you will see the channels from the last-used channel suite. Or,
• Click Retry to enter the login information again. Or,
• Click Abort. If you are accessing AppCenter through a network-connected Control Point PC, Abort lets you try to create a new channel suite. If you are accessing AppCenter locally, it lets you exit to Windows.
For assistance with your user name or password, consult your Windows administrator.
The K2 Solo 3G system might be ofine or have had difculty with the start up checks. There are various reasons why AppCenter is having difculty connecting to the K2 Solo 3G system; for example, the error might say there is no le system or that the K2 Solo 3G system has been taken ofine for maintenance.
• Verify that the host name or IP address is correct and see if you can correct the problem.
• If working locally, reboot the K2 Solo 3G system. If working from a network-connected Control Point PC, select System | Reconnect from the AppCenter System menu.

Viewing AppCenter system status messages

System status messages are displayed in the AppCenter status bar. There are two types of system status messages, as follows:
• Channel status messages — In normal operation, this type of message displays the current operating status of the selected channel.
• System error messages — If a problem develops with the system software or a hardware subsystem, this type of messageis displayed forapproximately 5 seconds. Afterward, the display returns to the channel status message and the error message is written to the status log le. When a message is written to the status log, a Status Icon indicates the severity of the message.

Embedded Security modes and policies

The Embedded Security solution protects against viruses and other unauthorized programs on the following Grass Valley systems:
• K2 Summit/Solo system
• K2 Media Server
• GV STRATUS server
• K2 Dyno S Replay Controller
Embedded Security prevents any unauthorized programs from running on the system. It contains a whitelist of programs that are authorized to run. Whenever a program attempts to run, it is checked against the whitelist. If the program is not on the whitelist, Embedded Security blocks the program from running. SiteCong, and any software deployed by SiteCong, is on the whitelist, so you do not need to manage Embedded Security in any way when using SiteCong to deploy software. All versions of SiteCong are compatible with Embedded Security.
When installingsoftware manually (without SiteCong) it might be necessary to manage Embedded Security. When necessary, you can put Embedded Security in Update mode. This mode allows you to manually install software that is not on the whitelist. Do not confuse Update mode with the idea that Embedded Security is "disabled". When in Update mode, Embedded Security is still active. While in Update mode, Embedded Security keeps track of any software you run or install and adds it to the whitelist. When you are done installing software and any required restarts, you must take Embedded Security out of Update mode so that it can protect the system. For software that requires a restart after installation, such as K2 system software and SNFS media le system software, Embedded Security must remain in Update mode until after the restart is complete.
No system restarts are required for entering or leaving Update mode, and a restart does not change the Update mode status. If in Update mode before a restart, the system remains in Update mode after a restart. You use the Embedded Security Manager to enter and leave Update mode.
The following policies apply to the Embedded Security:
• Use Update mode only as instructed by Grass Valley product documentation or as directed by Grass Valley Support. Do not do any other operations with Embedded Security Manager, unless under the direct supervision of Grass Valley Support.
• Do not keep Embedded Security in Update mode long-term, as Embedded Security does extra processing while in Updatemode and eventually problems arise when attempting to run software.
• Make sure that Embedded Security is not in Update mode when using SiteCong to install software. Updatemode interferes with SiteCong's automatic management of Embedded Security and causes problems running the software installed.
• Leave Embedded Security enabled for normal operation of your Grass Valley system. Do not disable Embedded Security except as instructed by Grass Valley product documentation or as directed by Grass Valley Support. Enabling and disabling Embedded Security requires a restart.
• Do not install any programs or modify any operating system settings unless approved by Grass Valley. By design, Embedded Security prevents any programs from being installed or from running that are not present when you receive the system new from Grass Valley. These Grass Valley systems are not a general purpose Windows workstations. The applications and conguration have been specically optimized on each system for its intended use as part of the Grass Valley system.
46 K2 Solo 3G Service Manual 06 November 2012
Page 47
• While Embedded Security is the key anti-virus component on these systems, you should still follow the Grass Valley anti-virus scan policy and scan all the devices in your Grass Valley system to ensure viruses are not propagated between machines.
Embedded Security is part of the K2 Solo 3G system generic disk image and the K2 Media Server generic disk image compatible with K2 software version 9.0 or higher. Both K2 Media Servers and GV STRATUS servers use the same generic disk image, so GV STRATUS servers inherit the Embedded Security solution. On K2 Solo 3G systems, the Embedded Security solution introduced with K2 software version 9.0 replaces the write lter from previous versions.

Replacing a RAID 0 drive

A K2 Solo Media Server’s disk modules are congured as RAID 0, so when one drive fails, all media is lost. To replace a RAID 0 drive, do the following:
1. Unbind the LUN that has the failed drive.
2. Remove the failed drive from the K2 Solo 3G system chassis.
3. Insert the replacement drive in the K2 Solo 3G system chassis.
4. Restart the K2 Solo 3G system.
5. Using Storage Utility on the K2 Solo 3G system, bind disks as RAID 0.
6. Restart the K2 Solo 3G system.
7. Using Storage Utility on the K2 Solo 3G system, make a new le system.
Always use the Storage Utility to physically identify the failed drive. To identify a drive, in Storage Utility right-click the drive and select Identify. This causes the disk lights to ash.
Refer to related topics in "K2 System Guide" for Storage Utility procedures.
Restart as prompted.
To remove and insert a drive, refer to the mechanical procedure for disk module removal.

About networking

When you receive a K2 Solo 3G system from the factory, it has a specic network conguration, including a loopback adapter and two of the four Gigabit Ethernet ports congured as a teamed pair. The Gigabit Ethernet ports,as viewedwhen looking at the rear panel, are represented in the following illustration.

Checking services

Depending on storage type (standalone or shared) of the K2 Solo 3G system, various services are turned off or on or set to different startup types. These services are automatically set by the K2 Solo 3G system software installation program and by the Status Server service whenever the K2 Solo 3G system starts up.
NOTE: Do not manually change the way services run on a K2 Solo 3G system.
If you suspect that services have been tampered with or for any reason are not set correctly, you can check their current settings in the Windows Services Control Panel. The table below provides the settings for the services that are critical to a correctly operating K2 Solo 3G system.

Recovering the media database

This section provides topics about recovering the media database.

About the automatic database backup process

Service procedures
Every 15 minutes the K2 system checks to see if any media operations have changed the media database. If a change has occurred, the K2 system creates a backup le of the media database. The backup le is saved in the same directory as the media database using a rotating set of three le names. These les are named media.db_bakX where X is the number in the rotation. Each time a backup occurs, the oldest backup le is overwritten. If some condition renders one of the backup les un-writable, the backup lefollowing that in the rotation is subsequently usedfor every backup until the condition is resolved.

Identifying a corrupt media database

The following symptoms could indicate a corrupt media database:
• On startup, the Grass Valley MetaDataService is unable to start. This is indicated in the Services control panel if the Grass Valley MetaDataService does not display as Started.
• The K2 log displays a “…le is encrypted or is not a database…” error.
As soon as you suspect a corrupt media database, stop all media access and take the K2 system ofine.

Restoring the media database

1. Stop all media access and take the K2 system ofine.
2. Navigate to the V:\media directory.
3. Make a copy of the media.db and media.db_bak* les and store them in a secure location.
4. Stop the Grass Valley MetaDataService as follows: For the standalone K2 system, use the Services control panel to stop the service.
5. Determine which backup le is the most recent good le by examining the le modication date on each backup le.
6. Rename the current media.db le (which is assumed to be corrupt) to another name, and rename the most recent good media.db_bakX le to media.db.

Using recovery images

This section provides topics about using recovery images.

About the recovery image process

An image of the K2 Solo 3G system system drive is provided with the product package. You can restore the K2 Solo 3G system from this image. This simplies the process of rebuilding a system in a disaster recovery scenario.
NOTE: This process is not intended as a means to backup and restore media.
When you receive your K2 Solo 3G system new from the factory, you receive a system-specic image for that particular K2 Solo 3G system. This factory image is stored on a bootable USB Recovery Flash Drive. Also on the Recovery Flash Drive is the Acronis True Image software necessary to create and restore an image. You can nd the Recovery Flash Drive in a holder in the front bezel assembly.
inconsistencies between the contents of the database and the le system.
After your K2 Solo 3G system is installed, congured, and running in your system environment, you should create anew recovery image to capture settings changed from default. This “rstbirthday” image is the baseline recovery image for the K2 Solo 3G system in its life in your facility. There is enough space on the Recovery Flash Drive to store the rst birthday image along with the factory image.
You should likewise create a new recovery image after completing any process that changes system software or data, such as a software upgrade. In this way you retain the ability to restore your K2 Solo 3G system to a recent “last known good” state.
You can also use the recovery image process on the control point PC.
NOTE: The recovery image process is an “off-line” process. Do not attempt this process while media access is underway.
The recovery image process that you should follow is summarized in the following steps.
• At the K2 Solo 3G system first birthday…
Boot from the Recovery Flash Drive.
Create a recovery image for the K2 Solo 3G system.
Create a recovery image for the Control Point PC.
• At milestones, such as software upgrades…
Boot from the Recovery Flash Drive.
Create a recovery image for the K2 Solo 3G system.

About saving and restoring settings while reimaging

If you are reimaging a K2 Solo 3G system with a generic disk image, you can run scripts to save the media le system and other settings beforethe reimage, then restore the settings after the reimage. Setting are saved and restored as follows:
Make sure the name is identical to the name it previously had. After start up, one or more device discovery windows can open. Allow processes to complete
without interference. If a Fibre Channel card driver, ignore until instructed later in this process. At rst start up after reimage, the system is in Embedded Security Update mode by default.
• Media le system (SNFS): You run scripts to save and restore these settings. After the settings are restored, on a standalone system you can access the media in the local media storage. On a SAN-attached system, K2Cong settings are restored so you can access media on the shared media storage.
• SID, computer name, and network settings: You run the script to save settings to a text le, so you can manually recongure as desired after the reimage.
If the media le system and settings are valid (not corrupt) on the K2 Solo 3G system before the reimage, it is recommended that you use the save/restore scripts to save your media and settings, thus saving time in the reimage process. However, if the media le system or settings are corrupt and your purpose for reimaging is to remove the corruption, it is likely that you do not want to use the save/restore scripts.

Saving settings before generic reimage

1. If you are working on a K2 client SAN-attached system, on the K2 SAN’s control point PC, use the K2Cong application to remove the K2 client system from the SAN.
2. Make sure you are logged in to the K2 Solo 3G system with administrator privileges.
3. Connect the USB Recovery Flash Drive to a USB port on the K2 Solo 3G system.
4. On the USB Recovery Flash Drive, navigate to the following location:
\tools\SaveRestoreScripts.
5. Run the following and wait for the process to complete:
ssave.bat
This saves current settings onto the USB Recovery Flash Drive in the \settings directory.
6. Disconnect the USB Recovery Flash Drive.

Troubleshooting problems

Step 1: Check configurations

Many times what appears to be a K2 Solo 3G system fault is actually an easy-to-x conguration problem. Check settings in Conguration Manager and verify that the system is congured as you expect. Refer to related topics in "K2 AppCenter User Manual" and "K2 System Guide".

Step 2: Check connections and external equipment

Loose or improperly connected cables are the most likely source of problems for the system. A quick check of all the cable connections can easily solve these problems. Refer to related topics in "K2 System Guide" for help with making connections. Check external equipment if you suspect a failure in a device connected to the K2 Solo 3G system.
Related Topics
Checking external equipment on page 74

Step 3: Check system status messages

While the K2 Solo 3G system is in operation, some problems are detected and reported in system status messages. To view system status messages, in AppCenter select Help | System Status.
When connecting to a K2 Solo 3G system from a control point PC using remote AppCenter, if there is an AppCenter system startup error, the error is reported during the connection attempt.
If the system status message indicates a problem, refer to related topics in "K2 Summit Production Client Service Manual".

Troubleshooting problems
Corrective ActionsPossible CausesProblem
Symptoms can include black video recorded or at playout, frozen video, slow performance, or inconsistent media access. These symptoms can be accompanied by StatusPane messages regarding disk problems or overrun/underrun conditions for encoders, decoders, or timecode.
The following causes can occur on their own or in combination to produce the problem:
• Disk oversubscription — This occurs when requests to the media disk exceed the disk’s bandwidth capabilities. This generally occur in extremecases when a combination of high-bandwidth operations are taking place, such as jog/shuttle, record/play on multiple channels, or streaming multiple clips.
• High CPU activity in Windows — This occurs when activities on the Windows operating system over-tax the capabilities of the CPU. This commonly happens when unsupported software has been installed that competes with K2 Solo 3G system applications. Virus scanners and screen savers can cause this type of problem, since they can start automatically and consume system resources.
• Encoder overrun — This occurs when an encoder is ooded with more data than it can process within its real-time requirements for recording.
• Decoder underrun — This occurs when a decoderis starved for data and cannot deliver enough to satisfy real-time requirements for playout.
• Disk faults — This occurs when a media disk is severely fragmented or has a bad blocks that interfere with some, but not all, media operations. For example, aparticular clip can be written on a bad block, so the problem occurs only onthat clip.
Try to re-create the problem. Identify all the interactions that affected the system and run all the same operations as when the error occurred. Record/play/stream the same clips. Investigate the functions that seem to push the systeminto the error state. If you determine that certain simultaneous operations cause the problem, re-order your workow to avoid those situations.If youdetermine that the problem is only on certain clips, investigate disk faults.

Removing and replacing FRUs

Removing and replacing FRUs
Field Replaceable Units (FRUs) are modular hardware components that can be serviced without disturbing other components in the system.
The pictures in the following topics show how to disassemble. Unless otherwise documented, re-assembly is the reverse.
To complete all FRU procedures, the following tools are required:
• Torx tool with T15 magnetic tip. This is the only tool needed for most FRU procedures. If additional tools are required, they are listed with the FRU procedure.
• #1 Phillips screwdriver
• #2 Phillips screwdriver
• 3/16” nut driver
• 1/4” nut driver
• Side cutters
NOTE: Only Grass Valley components are supported. Do not attempt to use components procured from a different source.
NOTE: Do not discard any hardware unless specically instructed to do so.
WARNING: To avoid serious injury from high currents, ensure that both power cords are disconnected prior to removing or replacing any parts.
CAUTION: This system contains board-level components that must be protected from static discharge and physical shock. Wear a wrist strap grounded to the system chassis when handling system components.

External Parts Removal

All the parts in this category can be removed and replaced without opening the K2 Solo 3G system cabinet.

Codec module removal

Access the codec module from the rear panel. Remove as illustrated.
NOTE: With a rm grip on the metal (EMI) bracket, ensure the board is level and parallel to the card guides to avoid damage to the components on the edge opposite the rear panel.
CAUTION: Improper handling can damage components on the board. Do not allow the board to come in contact with the chassis sheet metal during removal or installation. The components on the edge opposite the rear panel are the most susceptible to damage.
Before installing,inspect the codec module chamber and make sure no cables are protruding into the path of the codec module.
You must also remove any codec option (mezzanine) cards from the faulty codec module and install them on the replacement codec module.
After installing the replacement codec module, install the current version of K2 software. An over-install is all that is required. You do not need to rst un-install the software. This ensures that the board is ashed with the proper version to be compatible with K2 software.
