ESD Protection

Electronics today are more susceptible to electrostatic discharge (ESD) damage than
older equipment. Damage to equipment can occur by ESD fields that are smaller than
you can feel. Implementing the information in this section will help you protect the
investment that you have made in purchasing Grass Valley equipment. This section
contains Grass Valley’s recommended ESD guidelines that should be followed when
handling electrostatic discharge sensitive (ESDS) items. These minimal
recommendations are based on the information in the “Sources of ESD and Risks”
area. The information in “Grounding Requirements for Personnel” on page 26 is
provided to assist you in selecting an appropriate grounding method.

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

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.

Safety Summaries

Work Surfaces

Equipment

Materials

Grounding Requirements for Personnel

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.

Painted or vinyl-covered tables, chairs, conveyor belts, racks, carts, anodized
surfaces, plexiglass covers, and shelving are all static generators.

Any equipment commonly found in an ESD work area, such as solder guns, heat guns,
blowers, etc., should be grounded.

Plastic work holders, foam, plastic tote boxes, pens, packaging containers and other
items commonly found at workstations can generate static electricity.

The information in this section is provided to assist you in selecting a grounding
method. This information is taken from ANSI/ESD S20.20-2007 (Revision of ANSI/
ESD S20.20-1999).

About the K2 10G RAID

This chapter introduces the K2 10G RAID Storage. Topics include:

• “K2 10G RAID features” on page 34

• “K2 10G RAID components” on page 35

• “K2 10G RAID components” on page 35

K2 10G RAID features

The K2 10G RAID is a high performance, high availability mass storage system used
in K2 10G and K2 10G Expansion K2 Storage Systems. The K2 10G chassis
8 Gb/s host interface supports industry-standard technology.

The K2 10G RAID has a minimum of two host ports per controller. Each chassis is
equipped with two power supplies. Individual high-speed SAS links connect drives.

Depending on your configuration, the K2 10G RAID chassis contains:

• Two or four host ports

• Up to 12 SAS or SATA disk drives

• One or two hardware RAID Controllers in a 2U high rack-mountable chassis

18 November 2010 K2 10G RAID Storage Instruction Manual 34

Chapter 1 About the K2 10G RAID

The K2 10G RAID Expansion Chassis provides additional storage capacity. It
contains:

• Two Expansion Adapters

• Up to eleven K2 10G RAID Expansion Chassis can be connected to a single K2
10G RAID chassis

• A single disk-array storage system with up to 144 drives

K2 10G RAID components

The K2 10G RAID components are:

• One 2U high rack-mountable chassis

• One or two (K2 10G RAID redundant) RAID controllers or two expansion adapters
(Expansion chassis)

• As many as twelve SAS or SATA disk drives per chassis

• Two RAID chassis power supplies

All configurations have SNMP ports, slots for primary and secondary controllers, and
chassis with redundant power. Any unoccupied slot (RAID controller or disk module)
has a filler module to maintain air flow and compliance with electromagnetic
interference (EMI) standards.

The RAID controllers, expansion adapters, disk drives and power supplies are
hot-swappable field replaceable units (FRUs), which means you can add or replace
them while the K2 10G RAID is powered up.

An optional second RAID controller module in the K2 10G RAID allows for
continued access to the K2 10G RAID if the primary RAID controller fails. Refer to
the K2 SAN Installation and Service Manual for detailed connection and
configuration instructions.

NOTE: Every K2 10G RAID chassis controller includes a backup battery so that if
electrical power is lost, data stored in cache memory will be saved.

The chassis is a sheet-metal housing that contains chassis slots for the RAID
controllers or expansion adapters, disk drives, power supplies, and the LAN card.

There are two circuit board modules used: the RAID controller module and the
expansion adapter. The RAID controller module is in the primary RAID chassis. It
manages the disk drives and provides an interface to the K2 Media Server system or
switch. The expansion adapter is in an Expansion chassis. It manages the disk drives,
in conjunction with the connected RAID controller and provides an SAS interface to
the primary chassis.

The K2 10G RAID includes one or two RAID controller modules. This provides
redundant host interface ports.

The following figure shows a K2 10G RAID with the two RAID controller modules.

The RAID controller module has two host ports (HP0/HP1) and two Expansion
Chassis SAS ports (DL1/DL0). The Host ports require LCC cables (optical) for the
Fibre Channel connection to a K2 Media Server or to a Fibre Channel switch. The
Expansion Chassis Ports require SAS cables for the SAS connections with a K2 10G
Expansion Chassis. There are two port status LEDs for each Host port and each SAS
port. Refer to “Interpreting controller status LEDs” on page 56.

When the redundant controller option is not installed in the K2 10G RAID Storage
Chassis, a blank fills the other RAID controller slot.

Power supplies

There are two auto-ranging power supplies, each with a power cord. Each supply
supports a fully configured K2 10G External RAID and shares load currents with the
other supply, if it is present. The power supplies are designed so as to protect the disk
drives if you install them while the K2 10G External RAID is powered up. A disk with
power-related faults will not adversely affect the operation of any other disk.

Power supplies

Power
Supply1

Each power supply has status LEDs visible from the rear panel. The status LEDs are
described in the “Interpreting power supply status LEDs” on page 60. You can add or
remove one power supply in the RAID Storage Chassis while the RAID Storage
Chassis is powered up, but the operation must be completed within two minutes. Even
if a power supply is disabled, the fan in the non-functioning power supply can run off
the second power supply to cool the RAID for a couple of minutes.

Disk modules

Each disk module consists of a SAS or SATA disk drive in a carrier assembly. If a
disk drive fails, and needs replacing, you can do so while the RAID Storage Chassis
is powered up. Replacement disk drives begin rebuilding immediately after being
installed. (See “Removing and installing disk modules” on page 61.)

The following table shows how disk modules are identified based on the chassis
address and physical location. The chassis with an address set to 0 contains drives
from 00 to 0B; the expansion chassis are numbered X0 through XB, where X indicates
the chassis number.

K2 10G RAID power- up and initialization

This section gives information about connecting power and powering-on the
K2 10G RAID system.

Connecting electrical cables

For each chassis, there are two electrical cables (one for each power supply) that
should be connected to separate outside power sources.

WARNING: Make sure the power cords meet local safety and electrical
standards.

CAUTION: The K2 10G RAID system must be electrically grounded.
Operating the system without proper grounding can damage disk
drives. If the outlet you use is not grounded, make sure that a licensed
electrician replaces it and installs a grounding conductor.

To prevent the plug from being inadvertently disconnected, secure the electrical cable
into the outlet by doing the following:

1. Check that the power switch on the RAID chassis and those on the host system are
all set to OFF.

2. Insert the power cord into the power supply.

3. Secure the power cord with the power cable clamp.

4. Insert the plug of the power cord into an AC outlet. Use a grounded AC outlet.

Powering-up the K2 10G RAID system

1. Verify power and cabling.

2. Press and hold down the power button on the controller, as shown.

If the RAID chassis has two controllers, you can press the power button on either
controller. You do not need to press both power buttons.

Pressing the power button on a controller also powers on any connected Expansion
chassis. There are no power buttons on Expansion chassis.

3. Release the power button when the Power Good LED on the power supply is

illuminated. This takes 1-3 seconds.

4. Wait while the primary RAID chassis performs self-test and initialization. This

takes about four minutes. While this is taking place, the RDY LED is illuminated
with a steady on light.

5. Watch for the RDY LED to begin blinking at one second intervals. The LED might

turn off and back on two times before starting the one second blink pattern. When
the RDY LED is blinking at one second intervals, the self-test and initialization is
complete and the chassis is ready for use.

Refer to sections in Chapter 3, “Servicing the K2 10G RAID” for information on
interpreting status LED behavior.

NOTE: Refer to the K2 SAN Installation and Service Manual for complete system
power-up procedures.

K2 10G RAID power-down

NOTE: If your K2 10G RAID system is part of a shared storage system, refer to the
K2 SAN Installation and Service Manual for instructions on shutting down the
shared storage before powering down a K2 10G RAID.

To power-down the K2 10G RAID correctly:

1. Stop all read/write activity to the K2 10G RAID storage system.

2. On the primary RAID controller chassis, press and hold down the power button.

3. Release the power button in about 5 seconds, when the RDY LED blinks more

quickly, at a rate of about 2 blinks per second.

NOTE: Do not hold down the power button for longer than 15 seconds.

The power is turned off for the primary and expansion RAIDs. Power-off normally
occurs within 20 seconds. It is indicated when LEDs other than those on the power
supplies go off and the fans stop rotating.

Chapter 3

Servicing the K2 10G RAID

This chapter describes how to monitor K2 10G External RAID status and replace
Field Replaceable Units (FRU).

Topics include:

• “Maintenance procedures using Grass Valley Storage Utility” on page 52

• “Monitoring K2 10G External RAID status using NetCentral” on page 52

• “Interpreting disk module LEDs” on page 55

• “Interpreting controller status LEDs” on page 56

• “Interpreting expansion adapter status LEDs” on page 59

• “Interpreting power supply status LEDs” on page 60

• “Removing and installing disk modules” on page 61

• “Replacing a RAID controller or expansion adapter” on page 64

• “Replacing a power supply” on page 65

Maintenance procedu res using Grass Valley
Storage Utility

Several maintenance procedures can be performed using the Grass Valley Storage
Utility.

To perform the following tasks, refer to the K2 SAN Installation and Service Manual:

• Checking RAID controller microcode version

• Loading RAID controller microcode

• Identifying disk modules prior to removal

• Downloading K2 10G Expansion disk drive firmware

• Disabling a K2 10G Expansion RAID controller for removal

• Disabling a K2 10G Expansion disk module for removal

• Configuring K2 10G Expansion network and SNMP settings

Monitoring K2 10G External RAID status using
NetCentral

You can monitor K2 10G External RAID Storage systems using Grass Valley’s
NetCentral monitoring software. Enabled by SNMP, NetCentral can continuously
monitor the storage system and send notifications if there is a problem. The SNMP
agent software required for NetCentral monitoring resides on the RAID storage
device itself. As a result, the K2 10G External RAID appears in NetCentral as a
standalone device rather than as a subsystem of the K2 client.

• The RAID chassis configuration information is written to the first three disk
modules. If all of these disk modules are replaced with new devices with the power
supplies turned off, the information is lost. This condition is indicated by the
SERVICE LED blinking at a high rate at chassis power up. Therefore, do not
replace the first three disk modules with the power supplies turned off. Do not take
out more than one of the disk drives inserted in locations 00, 01, and 02 at one time.

• When multiple disk modules are subject to replacement, they must be replaced
with new disk modules one by one. Do not replace multiple disk modules
simultaneously. After checking that the Ready LED on the front panel of the
current disk module is lit, commence replacing the next disk module.

• Stick on the physical label indicating the installation position on each newly
installed disk module.

CAUTION: Handle a disk module gently and use an ESD wristband.
Do not remove a faulty disk module until you have a replacement
module (with the same part number) or a filler module available.

Removing and installing disk modules

Use the following instructions to replace a faulty disk module. It should be replaced
while the RAID chassis is running (hot-swapped).

Removing a disk module

NOTE: If a disk module has been bound, do not move it to another slot unless you
do not care about the data on the disk module . Each module has identifying
information written when it is bound. Moving it to another slot can make this
information inaccessible.

Generally, you should not remove a disk module unless it is faulty. Refer to

“Interpreting front panel LEDs” on page 53 and “Monitoring K2 10G External RAID
status using NetCentral” on page 52.

NOTE: If you wish to remove an operational disk module, use the Grass Valley
Storage Utility to disable the disk before removing it.

To remove the disk module:

1. Look in Storage utility and verify that the disk is reported as disabled or offline. If
it is not, disable the disk before proceeding.

2. Confirm the location of the faulty disk module by checking its Fault LED. Also
check NetCentral messages. NetCentral messages can report disk faults by disk
module number.

3. Open the disk module as illustrated in the following diagram.

Grass Valley Storage Utility.

Replacing a RAID controller or expansion adapter

Use the following instructions to replace a RAID controller or expansion adapter. On
a chassis with two controllers, the controller or expansion adapter should be replaced
while the chassis is powered up (hot-swapped).

On a chassis with two controllers, if the controller microcode on the replacement
controller is not the same as that on the other currently installed controller, the
microcode on the replacement controller is automatically upgraded or downgraded to
match that on the currently installed controller.

Removing a RAID controller or expansion adapter

To remove a RAID controller or expansion adapter:

1. If you are removing a redundant controller or an expansion adapter, identify the

module to be replaced using NetCentral or verify that the module’s Fault LED is
on. If you are removing an operational RAID controller, use the Grass Valley
Storage Utility to disable the RAID controller. If there is no redundant controller,
power down the system.

2. Disconnect all the cables.

NOTE: The cable to the SAS connectors has a blue tab labeled “Press.” Be sure to
press forward on the blue tab, rather than down.

3. Remove the power cable and the controller cable connected to the module. Note

where the cables connect to the module. The SAS cables for the K2 10G Expansion
Chassis are keyed so that one end can only be used with the DP-IN connector and
the other end can only be used with the DP-OUT connector.

4. Take an ejector of the module in each hand. Open them to the left and the right.

(The ejectors are locked at the bottom.) The module comes out by freeing it on the
left and right. The diagram below shows the ejectors on a controller.

5. Holding the ejectors in both hands, pull horizontally approximately 4 inches.

Glossary

The terms and definitions listed below are related to the storage system described in
this manual. Understanding them will aid your understanding of the storage system.

bind

In the context of a disk-array storage system, the procedure by which you
hardware-format one or more disk modules into one logical unit. Grass Valley
Storage Utility lets you bind disks into a logical unit recognized by the Windows
operating system, the media file system, and other software. Storage Utility labels this
group of disks a rank.

BTU (British Thermal Unit)

A standard measure of a device’s heat output.

cache

See storage-system caching.

direct-connect storage

K2 client models access their own external media storage drives that are contained in
a K2 RAID chassis. Referred to as stand-alone systems. See internal storage, shared
storage.

disk-drive module

Another name for disk module.

disk unit

A short name for physical disk unit.

disk module

A self-contained disk drive that slides into one of the slots in the front of the storage
system. It consists of the carrier assembly, which holds the disk drive and the
regulator board. Also called disk-drive module.

EMI (electromagnetic interference)

Electronic radiation emitted by an electrical device. The levels of EMI are strictly
controlled for data processing equipment. The EMI standards are explained after the
Notice page near the beginning of the manual.

ESD (electrostatic discharge)

The discharge of an accumulated electrical charge (static). This can severely damage
delicate electronic circuits.

field-replaceable unit

See FRU (field-replaceable unit).

FRU (field-replaceable unit)

A hardware assembly that can be replaced on site, instead of at the point of
manufacture.

A Broadcast Enterprise Server that incorporates IT server platform and storage
technologies. Includes both K2 Media Client and K2 Summit Production Client. The
K2 client can be used with internal, direct-connect, or shared storage.

power supply

An essential element of the storage-system power supply. A storage system can have
two power supplies. With two, it can survive failure of one supply. You can replace a
power supply under power without interrupting applications.

rank

See bind.

replace under power

The storage system provides replace under power capability, allowing you to replace,
for example, a disk module or a power supply module without powering down the
storage system. Applications continue while you replace the failed module.

SCSI (small computer system interface)

A well-known protocol and standard for connecting computers and peripheral
devices.

SES (SCSI enclosure services)

A functional subset of SCSI III commands that allow a server to communicate with
storage enclosures using their disk modules.

server

In the context of storage systems, a processor that runs an operating system and uses
a disk-array storage system for data storage and retrieval.
