GB (7,200 rpm) disk drives per chassis

• Two RAID chassis power supplies

All configurations have SNMP ports, sl ots for prima ry and secondar y controllers, an d
chassis with redundant power. Any unoccupied sl ot (RAID controller or disk mod ule)
has a filler module to maintain air flow and compliance with electromagnetic
interferen ce (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 Lx0 RAID is powered up.

An optional second RAID controller module in the K2 Lx0 RAID allows for
continued access to the K2 Lx0 RAID if the primary RAID controller fails. Refer to
the K2 Storage System Instruc tion Manu al for detaile d conn ection and conf igura tion
instructions.

NOTE: Every K2 Lx0 RAID chassis controller includes a backup bat tery so tha t if
electrical power is lost, data stored in cache memory will be saved.

The chassi s is a sheet-metal housing that contains chas sis 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 provide s an int er fa ce to th e K2 Media Serv er sys te m or
switch. The expansion adapter i s in an Expans ion chass is. It manag es the d isk drive s,
in conjunction with the conn ected RAID con trol ler and pr ovides an SAS interfac e to
the primary chassis.

The K2 Lx0 RAID includes one or two RAID controller modules. This provides
redundant host interface ports.

Power supplies

There are two auto-ranging power supplies, each with a power cord. Each supply
supports a fully config ured K2 Lx0 Exte rnal RAID an d shares load cur rents with the
other supply, if it is present . The po wer suppli es are designed s o as to prote ct the d isk
drives if you install th em while the K2 Lx0 External RAID is powered up. A disk with
power-related faul ts wil l not adversely affect the operatio n of any other disk.

Power supplies

Power
Supply1

Each power supply ha s s tat us LEDs vis ibl e from the rear panel . Th e status LEDs are
described in the “Interpre ting power sup ply status LEDs” on page 39. 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 tw o minutes. Even
if a power supply is disabled, t he fan in the non-fun ctioning power supp ly 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 40.)

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 chass is are numbered X0 through XB, where X indicat es
the chassis number.

K2 Lx0 RAID power-up and initializatio n

This section gives information about connecting power and powering-on the
K2 Lx0 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 lo cal safety and electric al
standards.

CAUTION: The K2 Lx0 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 discon nected, secure the elect rical cable
into the outlet by doing the following:

1. Check that the power switch on the RAID chassi s and those on the host syste m 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 Lx0 RAID system

Servicing the K2 Lx0 RAID

This chapter describes how to monitor K2 Lx0 External RAID status and replace
Field Replaceable Units (FRU).

Topics include:

• “Maintenance procedures using Grass Valley Storage Utility” on page 31

• “Monitoring K2 Lx0 External RAID status using NetCentral” on page 31

• “Interpreting disk module LEDs” on page 34

• “Interpreting controller status LEDs” on page 35

• “Interpreting expansion adapter status LEDs” on page 38

• “Interpreting power supply status LEDs” on page 39

• “Removing and installing disk modules” on page 40

• “Replacing a RAID controller or expansion adapter” on page 43

• “Replacing a power supply” on page 44

Maintenance procedu res using Grass Vall ey Storage Utility

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

To perform t he following tasks, refer to the K2 Storage System Instruction Manual:

• Checking RAID controller microcode version

• Loading RAID controller microcode

• Identifying disk modules prior to removal

• Downloading K2 Lx0 Expansion disk drive firmware

• Disabling a K2 Lx0 Expansion RAID controller for removal

• Disabling a K2 Lx0 Expansion disk module for removal

• Configuring K2 Lx0 Expansion network and SNMP settings

Monitoring K2 Lx0 External RAID status using NetCentral

You can monitor K2 Lx0 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 resul t , the K2 Lx0 External RAI D appears in NetCentral as a
standalone device rather than as a subsystem of the K2 Media Client.

• The RAID chassis configuration information is w ritten to the first three disk
modules. If all of these disk modules are rep laced with new device s 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 d isk modules wit h the power su pplies turn ed off. Do n ot take
out more than one of the disk dr ives inserted in locat ions 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 unl ess 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
informatio n inaccessible.

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

“Interpreting front panel LEDs” on page 32 and “Monitoring K2 Lx0 External RAID
status using NetCentral” on page 31.

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 util ity an d veri fy tha t the disk i s re ported as disabl ed or offl ine. I f
it is not, disable the disk before proceeding.

2. Confirm the location of the faul ty 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.

Replacing a RAID controller or expansion adapter

Use the following instru ctions to replace a RAID con troller or expansi on adapte r. On
a chassis with two co ntrolle rs, the controll er or expa nsion adapt er should be repl aced
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 repl acement con troller is au tomatically upgraded or d owngraded 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 disab le the RAID c ontroller. If there is no re dundant controller,
power down the system.

2. Disconnect all the cables.

NOTE: The cable to the SAS connectors has a blue tab labeled “Pres s.” 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 conn ect to the module . The SAS cables for the K2 Lx0 Expansio n
Chassis are keyed so that one end can only be u sed with the DP-IN connecto r a nd
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 lo cked at th e bottom.) The modu le 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.

6. Hold the module firmly in both hands and pull it all the way out.

CAUTION: The module might be hot.
