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 have been grounded.
NOTE: When a Personal Grounding strap is unavailable, as an absolute minimum, touch a
metal object that is touching the floor (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 configure 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 identifies 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 floors in a work area. The humidity level must be
controlled and should not be allowed to fluctuate 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 floor 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 floor’s surface. Carpeted
and waxed vinyl floors 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 messages can be observed on a locally connected VGA 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.
• NetCentral messages — If you are monitoring the system with NetCentral, the NetCentral
interface displays a variety of messages and other status indicators. Refer to the NetCentral Help
menu for a complete list of all the messages that a monitored device can send.

• 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 Summit 3G system might be offline or have had difficulty with
the start up checks. There are various reasons why AppCenter is having
difficulty connecting to the K2 Summit 3G system; for example, the error
might say there is no file system or that the K2 Summit 3G system has
been taken offline 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 Summit 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 Messages
Status bar
• System error messages — If a problem develops with the system software or a hardware
subsystem, this type of message is displayed for approximately 5 seconds. Afterward, the display
returns to the channel status message and the error message is written to the status log file. When
a message is written to the status log, a Status Icon indicates the severity of the message.
Related Topics
Troubleshooting problems on page 81
System status messages appear in the AppCenter status bar, which is located across the bottom of
the AppCenter window, and consists of a message area, several tool buttons, and a status icon. The
button icons appear only when the related function is active. In the position of the StatusPane button,
status icons appear.
The status bar displays information about the state of the delegated channel as well as low-level
error messages. (High priority error messages are displayed in pop-up windows.)
If you select a channel, a status message appears on the left-hand side of the status bar. If a potential
error arises while an application is running in a channel, a status message flashes briefly on the
left-hand side of the status bar, and an icon displays on the right-hand side. Double click on the icon
to open the status pane to view a more detailed message about the channel’s status.
The status icon changes depending on the status of the current status message.
Status pane
Current and previous system status messages can be viewed in the StatusPane. The system status
pane also displays general information such as the video and audio settings on the channels. To
open the StatusPane, click Help | System Status.

The StatusPane is used to view detailed system messages including status, warning, and error
messages. System status messages provide status icons and a description of the status event reported
by the message. If there is a problem, a corrective action is indicated. Use these messages along
with troubleshooting problems to determine if a service procedure is necessary.
If you have a remote AppCenter Channel Suite with channels from multiple K2 systems, the messages
from the different machines are combined in the StatusPane that you view from the Channel Suite.
To help you determine which machine is generating a message, each message lists the machine

About the write filter
The K2 Summit 3G system has a file-based write filter, which is a feature of the Windows embedded
operating system. With the write filter enabled, files can be created, modified, and deleted, but these
changes are held in a memory cache. When the K2 system restarts, these changes are lost and the
K2 system returns to its original state. This protects the K2 system from changes and increases
on-air reliability. For any system configuration change the write filter must be disabled otherwise
changes are lost at the next restart.
Some directories, such as C:\logs, C:\Profile\config, and C:\Profile\ChannelSuites, are
excluded from write filter protection, so that channel configuration and logs are saved. Do not
attempt to alter this list of excluded directories. If you suspect that write filter configuration has
been altered, use the recovery image process to restore to the default configuration.
To enable the write filter, the K2 system must be restarted. Likewise, to disable the write filter, the
K2 system must be restarted. You can enable/disable the write filter remotely using the K2Config
application or by using the SiteConfig application lock/unlock feature. The SiteConfig lock/unlock
feature applies to one K2 system at a time or on a group of K2 systems all at once. You can also
enable/disable the write filter from a local K2 system, but if you use the local method, do not also
use the SiteConfig method. If you enable/disable the write filter locally, the change is not
automatically sent to SiteConfig, so SiteConfig can not reliably indicate the current lock/unlock
state.

5. Click Commit.
6. Click OK.
Replacing a RAID 1 drive
If configured as RAID 1, you will repair the system by replacing the drive as soon as possible. You
can replace a single RAID 1 drive while continuing media operations.
Always use the Storage Utility to physically identify the failed drive. Accidentally removing the
wrong drive can destroy data. To identify a drive, in Storage Utility right-click the drive and select
Identify. This causes the disk lights to flash. Refer to related topics in "K2 System Guide" for Storage
Utility procedures.
Before removing the disk module, you should use Storage Utility to disable the disk.
To remove and insert a drive, refer to the mechanical procedure for disk module removal.
On inserting a RAID 1 replacement drive, if disk access (record/play operations) is underway, the
RAID controller automatically starts rebuilding the drive. You can verify rebuild status by looking
at the drive LED or by looking at the Service LED. If there is no media access currently underway,
you can use Storage Utility to force-start the rebuild process.
You can also check disk status in the Storage Utility by selecting the disk module icon in the device
tree. Status is reported in the right-hand pane. On completion, the disk drive status changes from

About networking
When you receive a K2 Summit system from the factory, it has a specific network configuration,
including a loopback adapter and two of the four Gigabit Ethernet ports configured as a teamed pair.
The Gigabit Ethernet ports, as viewed when looking at the rear panel, are represented in the following
illustration.
Restoring network configuration
Identify adapters
52 K2 Summit 3G Production Client Service Manual 02 February 2012
When you restore a system from its system specific image, network configuration is also restored
to the factory default settings. This is the recommended method of restoring network configuration.
However, if for some other reason you must configure network settings manually, use the tasks in
this section to restore the default network configuration.
On some systems, it is possible that the Microsoft Windows operating system has enumerated
network adapter names in an unpredictable sequence. You must identify adapters by their location
Page 53
Service procedures
rather than by the enumeration assigned by the Windows operating system and verify or modify the
adapter name as necessary.
1. Open Device Manager as follows:
a) On the Windows desktop, right-click the "My Computer" icon for your K2 system and select
Manage. The Computer Management window opens.
b) In the left pane select Device Manager.
Device Manager opens in the right pane.
2. In Device Manager, expand Network Adapters.
3. Verify the list of adapters. The adapters have similar names, with the first adapter having no
enumerator at the end of its name and the other adapters enumerated #2, #3, #4, etc.
The 1394 adapter is for the IEEE 1394a port on the rear panel. This port is for debugging purposes
only. It is not supported for customer use. Do not attempt to configure or otherwise use this port.

Depending on storage type (standalone or shared) of the K2 Summit system, various services are
turned off or on or set to different startup types. These services are automatically set by the K2
Summit system software installation program and by the Status Server service whenever the K2
Summit system starts up.
NOTE: Do not manually change the way services run on a K2 Summit 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 Summit 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 file of the media database. The
backup file is saved in the same directory as the media database using a rotating set of three file
names. These files are named media.db_bakX where X is the number in the rotation. Each time a
backup occurs, the oldest backup file is overwritten. If some condition renders one of the backup
files un-writable, the backup file following that in the rotation is subsequently used for 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 “…file 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
offline.
Restoring the media database
1. Stop all media access and take the K2 system offline.
2. Navigate to the V:\media directory.
3. Make a copy of the media.db and media.db_bak* files 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 file is the most recent good file by examining the file modification date
on each backup file.
6. Rename the current media.db file (which is assumed to be corrupt) to another name, and rename
the most recent good media.db_bakX file to media.db.

Using recovery images
This section provides topics about using recovery images.
About the recovery image process
An image of the K2 Summit system system drive is provided with the product package. You can
restore the K2 Summit system from this image. This simplifies 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 Summit system new from the factory, you receive a system-specific
image for that particular K2 Summit 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 find the Recovery Flash Drive in a holder in the front bezel
assembly.
inconsistencies between the contents of the database and the file system.
After your K2 Summit system is installed, configured, and running in your system environment,
you should create a new recovery image to capture settings changed from default. This “first birthday”
image is the baseline recovery image for the K2 Summit system in its life in your facility. There is
enough space on the Recovery Flash Drive to store the first 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
Summit 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 Summit system first birthday…
Boot from the Recovery Flash Drive.
Create a recovery image for the K2 Summit 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 Summit system.

Boot from the Recovery Flash Drive.
Read the image from the Recovery Flash Drive or from the location that you stored the image.
• If you need to restore the Control Point PC…

Read the image from the location that you stored the image.
Use the following procedures to implement the recovery image process as necessary.
Creating a recovery image
Before creating a recovery image, determine the storage location for the image. Grass Valley
recommends that you store the recovery image on the Recovery Flash Drive, and this task provides
instructions for that location. If you use a different location, such as a network connected drive or
another connected USB drive, alter the steps in this task as appropriate.
1. Make sure that media access is stopped and that the system on which you are working is not
being used.
2. If you have not already done so, connect keyboard, monitor, and mouse.
3. Do the following:
a) Insert the Recovery Flash Drive into a USB port.
b) Restart the machine, or power on if currently shut down.
The machine boots from the Recovery Flash Drive, into a version of Windows stored on the

About saving and restoring settings while reimaging
If you are reimaging a K2 Summit 3G system with a generic disk image, you can run scripts to save
the media file system and other settings before the reimage, then restore the settings after the reimage.
Setting are saved and restored as follows:
• Media file 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, K2Config 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 file, so
you can manually reconfigure as desired after the reimage.
If the media file system and settings are valid (not corrupt) on the K2 Summit 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 file system or settings are corrupt
02 February 2012 K2 Summit 3G Production Client Service Manual 73

and your purpose for reimaging is to remove the corruption, it is likely that you do not want to use
the save/restore scripts.

Installing the Discovery Agent on a K2 Summit system
If the device that you plan to manage with SiteConfig does not have a SiteConfig Discovery agent
installed, use this topic to verify and, if necessary, manually install SiteConfig support software.
Doing so allows SiteConfig to discover and manage the device. If the device has any version of the
SiteConfig Discovery Agent currently installed, you should use SiteConfig to upgrade the Discovery
Agent, rather than installing it manually.
1. On the device you plan to manage with SiteConfig, open the Windows Services Control Panel
and look for the following required item:
• ProductFrame Discovery Agent
2. Proceed as follows:
• If you find the required items, no further steps are necessary. SiteConfig support software is
installed.
• If a required item is not present, navigate to your SiteConfig files. If you do not already have
these files in convenient location, you can find them on the PC that hosts SiteConfig, in the
SiteConfig install location. Then continue with next steps as appropriate.
Service procedures
3. To launch the program that installs the ProductFrame Discovery Agent Service do the following:
a) Copy the Discovery Agent Setup subdirectory to the device.
b) In the Discovery Agent Setup directory, double-click the
DiscoveryAgentServiceSetup.msi file.

Troubleshooting problems
Step 1: Check configurations
Many times what appears to be a K2 Summit system fault is actually an easy-to-fix configuration
problem. Check settings in Configuration Manager and verify that the system is configured 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 Summit system.
Related Topics
Checking external equipment on page 84
Step 3: Check system status messages
While the K2 Summit 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 Summit 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 this document.
NOTE: Do not use the MegaRAID utility on a K2 Summit system. This utility is for use by
qualified Grass Valley Service personnel only. When this utility is opened it scans the SCSI bus
and interferes with record and play operations.

Viewing AppCenter system status messages on page 43
Step 4: Identify problems using the startup sequence
The startup sequence is your primary tool for identifying a K2 Summit system fault. As the different
levels of the K2 Summit system system become operational in the startup process, the primary
components of the system are checked. You can identify most problems by evaluating the messages
and other indicators that occur during the startup sequence.
NOTE: This procedure assumes that the K2 Summit system is not in Storage Utility’s “offline”
mode.
To identify problems using the startup sequence, do the following:
1. Connect mouse, keyboard, and monitor. You must observe the VGA screen and be able to interact
with the system via keyboard and mouse to fully identify problems.
2. Restart the K2 Summit system.

Shutdown/restart problems
If the K2 Summit system is inoperable due to an error it can affect the operation of the standby
button. If pressing the standby button does not shut down the K2 Summit system, press and hold
the button for five seconds. This forces the K2 Summit system to execute a hard power down. If
that doesn't work or if after the hard power down the system does not boot, disconnect then reconnect
the power cable(s).
The K2 Summit system is set to attempt to boot from a USB drive first, before it boots from the
boot media card. If you have a drive connected to a USB port that does not contain an appropriate
operating system and you start up the K2 Summit system, an error message is displayed and the
boot up process halts.

Available Storage. If the Time Dome is filled
it confirms that the destination K2 Summit
system is out of space. Make space on the
media drives by deleting unused clips and
emptying the Recycle Bin.
Use the Storage Utility to check the file
system.

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 extreme cases
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 Summit
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 flooded with
more data than it can process
within its real-time requirements
for recording.
• Decoder underrun — This
occurs when a decoder is 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, a particular clip can be
written on a bad block, so the
problem occurs only on that 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 system into
the error state. If you determine
that certain simultaneous
operations cause the problem,
re-order your workflow to avoid
those situations. If you determine
that the problem is only on
certain clips, investigate disk
faults.

Troubleshooting problems
Corrective ActionsPossible CausesProblem
When importing or exporting
(sending) between K2 Summit
systems a “…failed to
connect…” message appears
and the operation fails.
There is a problem with
Windows networking or there is
a mis-spelling with the host
name as entered in
Configuration Manager.
The K2 Summit system to which
you are trying to connect is not
operating or the network is
mis-configured.
Check networking as follows:
- Check basic Windows
networking. Use Windows
Explorer to test a basic copy
operation to the machine to
which you are trying to connect.
If basic networking fails, use
standard Windows procedures
to troubleshoot and correct your
network.
- If the Windows network is
working properly, in AppCenter
select System | Configuration |
Remote and verify that the name
of the machine to which you are
trying to connect is spelled
correctly and has no extra spaces
or characters.
Verify that the K2 Summit
system to which you are trying
to connect is operational and that
the network is configured
correctly. Verify that the name
of the K2 Summit system is
entered correctly in the
Configuration Manager Hosts
page. Refer to networking topics
in "K2 System Guide".
A networked device does not
appear in the “Import” and
“Send to” dialog boxes, even
though it is present on the
Windows network.
The device is not entered as a
host.
In AppCenter select System |
Configuration | Remote | Add and
enter the name of the machine
to which you are trying to
connect. Make sure it is spelled
correctly and has no extra spaces
or characters. Also check the
hosts file. Refer to networking
topics in "K2 System Guide".
Verify FTP server.If a SAN K2 client, the client’s
K2 Media Server with role of
FTP server is not operational.
Files do not appear in” Send
To” or “Export” dialogs.

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.
Unless otherwise indicated, you need only a Torx tool with T15 magnetic tip to remove and replace
parts in the K2 Summit system.
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 specifically 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 Summit system
cabinet.
Front bezel assembly removal
You can remove the bezel assembly while the K2 Summit system is operating. If you do so, make
sure you replace it within three minutes to ensure that the correct operating temperature is maintained.
1. To remove the front bezel assembly, proceed as illustrated.
