ABOUT THIS BOOK
This book presents information on the system design and operation of the Open Reliable Communications Architecture (ORCA) telephony 4K gateway. The purpose of
this information is to help you install, use, and maintain the ORCA-4K gateway.
WHO SHOULD USE THIS BOOK
This book is for product distributors, systems integrators, systems analysts, and network administrators who design, install, configure, and maintain wide area networks
(WANs) and large-scale communications applications. It contains conceptual and
practical information about how to use the ORCA-4K gateway within your network.
CONVENTIONS USED IN THIS BOOK
This book uses specific conventions to show the following types of information:
•
Number usage
•
Replaceable input values
•
Messages
Read the following sections to learn more about how this information is shown in the
rest of the book.
Notes, Cautions, and Warnings
Notes show useful information and/or contain information requiring attention.
Cautions show information requiring extra attention.
ORCA-4K Hardware Manual
10
Warnings are information that, if not followed, could result in injury or
equipment damage.
How Numbers Are Used
When numbers are shown in this book, they can appear as descriptive values or as
data to be manipulated internally. Decimal values are used frequently; however,
alternate number bases are useful when internal data is shown.
Large Decimal Numbers
Numbers greater than 9999 display in SI metric style, where whole numbers that
contain more than four digits are broken into groups of three digits that are separated by spaces. For example, the number sixteen thousand three hundred eighty
three is shown as 16 383. This avoids confusion between American and European
punctuation conventions. However, a number that is internally manipulated by a
computer is shown without punctuation or spaces. For example, notice how the value
65 535 appears in the following instruction without a space or a thousands separator
within the number:
Specify 65535 as a maximum value
Numbers with Different Bases
All numbers shown in this book are decimal values unless the number base is binary
or hexadecimal. In these cases, an identifier precedes a binary or hexadecimal number. For example:
•
the value of binary 1010
•
the value of hex 4F
Replaceable Input Values
In some cases, you can insert user-defined values into commands or you can specify
local paths and filenames. These variable values are shown in italic typeface.
For example, you might be asked to specify the name of your server in this path:
A:\LOGIN\LOGIN servername
ORCA-4K Hardware Manual
11
The italic typeface shows that you need to replace servername with your local server
name.
When prompted for variable input represented by lower-case letters, follow these conventions:
When You See This
Substitute This Value
b
Any binary digit
h
Any hexadecimal digit
n
Any decimal digit
x
Any alphabetic value, such as:
x:\DOS
where you substitute the correct drive letter
for x
Multiple letters
A series of digits, such as:
FIRST 2 HEX BYTES: hhhh
where you substitute four hexadecimal digits for hhhh
When prompted for variable input with embedded decimal points, replace the variable digits and let the decimal points remain to separate 32-bit dotted-decimal
address segments. For example, you might be prompted to supply a 32-bit, dotteddecimal address in this format:
nnn.nnn.nnn.nnn
where nnn is a decimal value from 0 through 255. Leading zeros are not required.
GETTING HELP
If, after installing and configuring your Nuera equipment, you cannot establish communications to or from the unit, carefully review the information in this book and in
the other ORCA books prior to calling Technical Assistance Center (TAC).

Introduction
High-Reliability
The ORCA-4K’s robust platform provides sufficient fault tolerance and redundancy to
guarantee high availability. Because ORCA-4K carries large amounts of revenue-producing voice traffic, hardware or software faults are contained and not permitted to
affect other system resources.
The ORCA-4K design includes full 1+1 redundancy for all control, signaling, and
voice processes in the system.
Scalability
Depending on the application, the ORCA-4K can support up to six DS3s, two STM-1,
or two OC-3 of packetized voice. Please refer to the specific application manual for the
exact number of voice channels supported.
Hot-Swap Capability
The ORCA-4K modules are hot-swapable in the event of a physical failure. These
modules require no special tools or training to perform a field replacement.
NEBS Compliance
The ORCA-4K product complies and is certified to the Network Equipment Building
System (NEBS) Level-3, Zone 4 requirements.

CHASSIS
AND
COMPONENTS
This chapter presents the functional architecture of the ORCA-4K gateway. It introduces the major gateway components, their functions, and inter-activities.
The ORCA-4K chassis consists of a fault-tolerant fan tray, dual -48VDC inputs and
front and rear modules that are hot-swappable and field replaceable. The modules
are separated by a midplane which is functionally equivalent to a backplane. The
front module is the Voice Processor Module (VPM). It is active (that is, it has powered
circuitry), redundant and provides an optical Gigabit interface. When the Optical
Connector Modules (OCM) are present above the top VPM, the ORCA-4K is capable
of OC-3 (SONET) or STM-1 (SDH). The rear modules are the Bits Clock Module
(BCM), DS3 Connector Module and Alarm Module. The ORCA-4K includes a mixture
of active and passive (no active circuitry) modules. Some of these modules are redundant (such as the BCM) and others are shared by the VPM and gain redundancy
internally through the midplane (DS3 Connector and Alarm Modules). All metallic
interfaces linking the system to the network are located on the rear modules. The
OCM and DS3 Connector Modules are system-dependent and are not present in
every system.

Chassis and Components
Chassis Overview
Dimensions
The ORCA-4K chassis is three rack units (3RU) high, or 5.25 inch (13.3 cm) high x
17.5 inch (44.5 cm) wide x 22 inch (49.5 cm) deep. It can be front or center mounted on
an Electronics Industry Association (EIA) standard 19 inch relay rack or optionally,
on a 23 inch relay rack when extended mounting ears are purchased, see "Replacement Modules and Components" on page 58.
Weight
The ORCA-4K chassis weighs ~ 33 lbs. (15 kg).
Fan Tray
The ORCA-4K chassis contains a fault-tolerant fan tray with 12 high reliability tubeaxial fans. The tray is hot-swappable, located on the left side of the chassis and capable of sufficiently cooling the system modules within an operating temperature range
of 5 to 50° C (23 to 122° F).
The system is capable of monitoring the fan tray performance and in the event of a
fan or fan tray failure, will generate an alarm. Although, the system will continue to
operate within acceptable temperature limits with up to three failed fans, it is recommended the user replace the entire fan tray as soon as possible. The gateway will also
operate for up to 20 minutes (at ambient temperature) without a functioning fan tray,
but this is not recommended. A failed fan tray should be replaced immediately. Since
the fan tray is hot swappable, the new fan tray can be installed while the gateway is
running, thereby restoring full cooling capacity.

GATEWAY MODULES
This chapter describes the function, features, and hardware connections of the
ORCA-4K gateway modules.
Voice Processing Module (VPM)
This section describes the VPM’s installed in the front of the chassis. The VPM acts
as the host cluster and the voice processor.
Redundancy
The ORCA-4K gateway is designed to allow for distributed execution of control and
processes to minimize service loss due to potential failures. In the event of a failure,
the VPM can be removed and replaced (hot-swapped), thereby, permitting the gateway to continue to function.
The ORCA-4K gateway design provides for two VPMs; one is a hot standby for the
other. In normal operation, the active VPM monitors the operational status of the hot
standby VPM and the hot standby VPM monitors the status of the active VPM.
In the event of a failure, the ORCA-4K gateway sends a trap alarm to the Nuera NetConductor EMS and then switches control to the standby VPM, thereby maintaining
service. The switchover process takes ~ 50 milliseconds, and there is no loss of stable
calls.
The ORCA-4K gateway then continues operation under control of the other VPM,
until a failure again initiates a switchover. This can also be activated by issuing the
appropriate command from the Nuera NetConductor EMS.
ORCA-4K Hardware Manual
19
Gateway Modules
After a switchover, the now inactive VPM can be diagnosed via the Nuera NetConductor EMS.
Gigabit Ethernet Transceiver and LC Style Optical Connector
The gigabit optical ethernet transceiver as shown in Figure 3 is located on the VPM.
The gigabit serial optical transceiver is compliant with the Fiber Channel, 100-M5/
M6-SN-I and Gigabit Ethernet 1000 Base-SX standards. This transceiver features a
high reliability, 850 nm, High Speed, Oxide VCSEL Laser coupled to a LC optical
connector. This transceiver meets Class 1 laser eye safety requirements. It has GBIC
functionality in 1/2 the width. The transceiver complies with the Small Form Factor
Plug (SFP).
You must provide the optical fiber and LC style optical connector to connect to the
VPM transceiver.
Eye Safety: The LC Series Optical Transceiver on the VPM is an international Class 1 laser product per IEC 825-1: 1993, and per CDRH, 21 CFR
1040 Laser Safety Requirements. The transceiver is an eye safe device when
operated within the limits of this specification. Operating this product in a
manner inconsistent with intended usage and specification may result in hazardous radiation exposure.
Tampering with this laser based product or operating this product outside the
limits of this specification may be considered an act of “manufacturing,” and
will require, under law, recertification of the modified product with the U.S.
Food and Drug Administration (21 CFR 1040). The use of optical instruments with this product will increase eye hazard. At the normal operating
current, optical output power with an unaided eye can be as much as 30 uW
at a wavelength of 850 nm. Approximately ten times this power level could
be collected with an eye loop. Under a failure condition, this level could
increase by a factor of two.

VPM Sub-Modules
The VPM contains a number of sub-modules, each assigned a separate processing
task.
With exception of the DSP module: VPM sub-modules are not field replacable. In the event of a suspected VPM sub-module failure, the entire VPM
should be returned. Removal of sub-modules may void your warranty.
Network Processor (NP) Module
The NP module routes all packet traffic into and out of the system, as well as
between the internal boards. This module is not field serviceable.
DS3 Daughter Board (DS3DB)
This card is only installed on VPMs labeled VPM/DS3. The DS3 daughter board
handles the terminations for the DS3 interfaces and distributes traffic to the
DSPs. This module is not field serviceable.
OC3 Daughter Board (OC3DB)
This card is only installed on VPMs labeled VPM/Optical. The OC3 daughter
board handles the terminations for the optical interface (OC-3 or STM-1) and distributes traffic to the DSPs. This module is not field serviceable.
Digital Signal Processor (DSP) Modules
The DSP modules are the payload processors. They are responsible for processing,
encryption, and packetization of the traffic on the voice channels within the
ORCA-4K gateway. These modules are field serviceable and upgradeable.

Gateway Modules
Media Interface Modules
The ORCA-4K Media Gateway can be configured for either metallic DS3 interfaces or
optical (OC-3 or STM-1) interfaces. A ORCA-4K is said to be configured as metallic
DS3 if the VPM cards are of type “DS3”, which means they have a DS3DB_MODULE
installed. An “Optical” VPM card has an OC3DB_MODULE installed and is said to
be configured as optical OC-3 or optical STM-1. NetConductor automatically
adapts to the configuration of your ORCA-4K. For example, if it detects a ORCA-4K
configured for metallic DS3 interfaces then you will see DS3 interfaces in the inventory of your Network Element (instead of OC-3 or STM-1).
DS3 Connector Module
The DS3 Connector Module, as shown in Figure 4, provides TX/RX connections for
the DS3 lines. There are two DS3 Connector Modules per gateway, each providing
three DS3s of connectivity. DS3 redundancy is achieved through internal DS3 circuitry that duplicates the signals from each incoming DS3 link and sends identical
information to each VPM.
Figure 4. DS3 Front Panel Connections
Interfaces and Specifications
The DS3 Connector Module (two per system) has the following interfaces and specifications:
•
Three RX BNC ports

Gateway Modules
Optical Connector Module (OCM)
The OCM card hardware supports both OC-3 (SONET) and STM-1 (SDH) applications. Optical units are configured for OC-3 (SONET) at the factory at the time of
order/shipment. Each OCM interfaces is 1+1 redundant, unidirectional and has nonrevertive protection switching. Viewed from the front, as shown in Figure 5, the OCM
interface on the left is designated Working, while the interface on the right is Protect.
•
When configured for OC-3 (SONET) the interface enables interconnection to optical
networks as defined by GR-253-CORE from Telcordia. In this case, the system can be
configured to transport as many as 4,032 DS0s via 2 OC-3 level 1 payloads.
•
When configured for STM-1 (SDH) the interface enables interconnection to the
synchronous optical networks using the ITU-T standards. In this case, the system
can be configured to transport as many as 3,906 DS0s via 2 STM-1 (Synchronous
Transport Module, level 1) payloads.

INSTALLING
THE
CHASSIS
The installation of the ORCA-4K gateway requires a few simple tasks.
Site Preparation
Power Input
You will need -48 VDC nominal (42 to 60 VDC), 5A minimum per gateway. Nuera recommends that a qualified professional determine the appropriate wire gauge based
on the distance from the power source and the power input requirements.
Redundant Power Feeds
Nuera recommends redundant power feeds from separate power sources to ensure
the continuous operation of the gateway. This ensures proper operation of the gateway in the event of a power loss from one of the sources.
Airflow and Thermal Cooling Requirements
The ORCA-4K gateway is equipped with a fan tray for cooling the system modules.
The air intake is located on the right side (as viewed from the front) and the exhaust
vents are located on the left and left-rear of the chassis. To prevent overheating, the
air intake must not be obstructed. After installation of the gateway, you should avoid
installing other equipment that exhausts hot air directly into the ORCA-4K air
intake.
ORCA-4K Hardware Manual
26
Installing the Chassis
The gateway produces heat at a maximum of 854 BTU/hr. The facility air conditioning system must be capable of handling the heat load to reduce the ambient air temperature to an acceptable level for proper operation.
Space Allocation Guidelines
The gateway can be installed in a 19 or 23 inch EIA standard open relay rack. Nuera
can supply a 23 inch rack adapter, if necessary. See “Replacement Modules and Components” on page 58. An enclosed cabinet is not recommended unless it can provide
sufficient cooling capacity to dissipate 854 BTU/hr per gateway.
Chassis Mounting Guidelines
The chassis can be flush or mid-mounted. A single gateway requires 5.25 inches (3RU
or 133.35 mm) of vertical rack space, 22 inches (558.8 mm) of rack depth and weighs
approximately 33 lbs (15 kg).
Redundant BITS Clock Inputs
Nuera recommends redundant BITS Clock inputs derived from a Stratum 1 timing
source to ensure a continuous clocking source and guard against timing slips on the
TDM interfaces. The BITS clock input is located on the BITS Clock Module.
100 Base-T Ethernet Connections
The ORCA-4K only supports full-duplex mode on the 100 Base-T Ethernet ports.
Autonegotiation is not supported. You must configure the remote switch to auto negotiation off, full-duplex mode.
1000 Base-SX Ethernet Connections
The ORCA-4K does not support autonegotiation on the 1000 Base-SX Ethernet ports.
You must configure the remote switch to autonegotiation off, full-duplex mode. Use
the optical cable guide lances on the front of the chassis to secure the 1000 Base-SX
Ethernet optical (fiber) cable from the VPMs.
The 100Base-Sx Ethernet optical cables can be pinched or damaged if they
are not secured to the chassis guide lances using a nylon tie-wrap when
installing the front cover.
ORCA-4K Hardware Manual

Installing the Chassis
Figure 8. ORCA-4K Gateway Chassis Optical Cable Guide Lances
DS3 Connections
You should be prepared with the proper length 75 ohm DS3 cables prior to connecting
to the remote DS3 equipment. If necessary, these can be purchased from Nuera. Also,
you should confirm the line type used by the DS3 equipment needed to configure the
gateway via the Nuera NetConductor EMS.
Optical Connections
You should be prepared with the proper length single mode fiber optic cable. The
cable must also be compatible with the Small Form Factor Pluggable (SFP) MultiSource Agreement (MSA) transceiver with LC connectors and support OC-3
(SONET)/STM-1 (SDH). The optical wavelength is 1300 nm and the transceiver is
intended for IR (less than 15 km) operation. Also, you should confirm the width setting used by the OC-3 (SONET) or STM-1 (SDH) equipment needed to configure the
gateway via the Nuera NetConductor EMS.

Installing the Chassis
Installing the Chassis
The ORCA-4K is shipped in a protective carton to prevent damage during shipping.
The shipping carton contains the following items:
•
ORCA-4K gateway chassis (with modules installed)
•
Aesthetic front cover
•
Cable assemblies (optional)
•
ORCA-4K gateway documentation and software on CD
To install the chassis:
1. Remove the ORCA-4K chassis from its shipping carton.
2. The ORCA-4K chassis is shipped with its rack mount ears positioned for front
(flush) mounting. To change the mount position of the chassis, use a #2 Phillips
screwdriver to remove the three #8-32 screws affixing each rack mount ear. Reposition the rack mount ears to the desired mount position. Replace all screws.
3. Lift the chassis into the rack so that the chassis mounting ears are aligned with
the rack holes. Partially install one rack screw in the bottom corner of each side
for the keyhole cutouts. Set the chassis over the partially installed rack screws,
then install the remaining rack screws (rack screws not provided).
4. For racks with equipment shelves installed, lift the ORCA-4K chassis and position it on the shelf.
5. Snap the aesthetic cover onto the front of the chassis.
Connection to the -48 VDC power source must be made with the appropriate
wire gauge based on the power input requirements and the distance of the
wire from the power source. Nuera recommends that a qualified professional
determine the wiring and installation requirements for the site.
ORCA-4K Hardware Manual
29
Installing the Chassis
Connecting Main Power and Ground
The ORCA-4K gateway is configured for DC power. Nuera recommends that your
installer provide two independent fault current protected -48 VDC power feeds. The
DC power feeds should be fault current protected at 5A minimum.
Installation must be performed by a qualified professional who is skilled in
the installation and connection of power distribution systems, and is knowledgeable of applicable municipal electrical code requirements.
Before connecting the DC power mains, a separate ground strap (which is
connected to a centralized ground network in the installation site) must be
connected to the ground terminal at the rear of the chassis. The strap used for
this purpose must be 14 AWG or larger. A ring tongue terminal for a #10
stud must be securely crimped to the end of the wire that connects to the
ORCA-4K gateway ground terminal. Also, ensure the power cord(s) or
cable(s) are not connected to the main power source and cannot carry a voltage potential until after this procedure is complete.
To connect power to the chassis:
1. Place the #10 ring tongue terminal of the ground strap over the threaded stud of
the chassis ground terminal. Fasten the #10 star washer and a #10-24 nut on the
threaded stud. Tighten the nut to a torque of 6 ft-lb. (0.83 kg-m).
2. Remove the terminal cover to access to terminal posts. The terminals for DC
power are labeled -48VDC and BAT RTN (BATTERY RETURN) and are wire
ready, meaning the wires need to be stripped to the appropriate length prior to
being clamped down by the screws on the DC terminal block (See Figure 9).
Figure 9. ORCA-4K Gateway DC Power Terminal Posts
3. Make power connections to the rear of the chassis. Tighten each screw to a torque
of 20 in-lb. max.
4. Replace the terminal cover.
ORCA-4K Hardware Manual

Installing the Chassis
Applying Power
Turn on power to the chassis by switching both circuit breakers to the On (|) position. The ORCA-4K gateway will run a power-on self-test to ensure proper initialization of the gateway.
If either terminal block is not connected or both circuit breakers are not
turned on, the LED on the fan tray and a LED on the VPM will remain red.
The system will also send out a trap alarm indicating there is no redundant
power.

CONFIGURATION
This chapter describes the basic configuration functions performed through the Craft
port of the ORCA-4K gateway. It also provides specific instructions for configuring a
gateway using craft port commands.
Once the basic configuration is complete through the Craft port and the system has
been power-cycled, you should complete the configuration using Nuera’s NetConductor EMS. Refer to the NetConductor User’s Guide and the ORCA-4K Application
User Guide to learn how to fully configure and monitor the gateway.
The Craft Port
The Craft port plays a small yet crucial part of bringing an ORCA-4K gateway online
in a network. Located on the BCM, this is a DB9 (M) serial port intended to connect a
computer directly into the gateway to assign basic configuration information.
Connect a null modem cable to the active BCM Craft port. The active BCM is connected to the active VPM; for example, VPM1 is connected to BCM1. The active VPM
will also have its green “active” LED illuminated on the front panel.
Once a computer has been connected to the port, use a terminal emulation program
such as Procomm PlusTM or Hyperterminal to access the gateway. Use the settings
below to correctly configure the emulation program:
•
9600 bps (ANSI ASCII format)

Craft Port Commands
This section presents a list of ORCA-4K gateway commands that can be entered
through the BCM Craft port. These commands are initially used to configure the
gateway. Once the gateway is functional, the remainder of the configuration can be
performed through the Nuera NetConductor EMS.
The default password for the ORCA-4K gateway is: nuera. You should modify the
default password prior to configuring the gateway.
Take special care with your password as there is no way to recover a lost
password.

Ethernet Commands
The ethernet command group provides LAN configuration parameters for the
ORCA-4K gateway. There are five ethernet commands:
•
ethernet control <100 Base-T Floating IP address>
•
ethernet media <1000 Base-SX Floating IP address>
•
ethernet bkcontrol <Background Control IP address>
•
ethernet bkmedia <Background Control IP address>
•
ethernet show
The ethernet control and media commands set the floating IP address, default
gateway, and subnet mask used by the active VPM, regardless of the slot. The ethernet bkcontrol and bkmedia commands set the fixed IP addresses for the control ports and media ports for both VPMs.
After the ethernet addresses are modified, the gateway must be power-cycled
for the changes to take effect.
In addition to the configuration commands above, a command for viewing a subset of
the Ethernet statistics for each port is included (ethernet control stats, ethernet

four RTP ports per channel. For example, this means with a default callpro rtpbaseport of 11000:
•
Six DS3 capacity will result in a RTP port range of 11000 to 27128 (4032 channels
per DS3). The port number may be any even number between 7000 - 48000.
•
Two STM-1 capacity will result in a RTP port range of 11000 to 26625 (3906 channels per STM-1.) The port number may be any even number between 7000 48000.
CALLPRO RTPBASEPORT [PORT NUMBER]
RTP voice packets are sent and received on even UDP port numbers while
RTCP voice control packets are sent and received on odd UDP port numbers.
CallPro MGCInterface
The callpro mgcinterface command indicates which interface is connected to the
MGC. The MGC interface may be configured to control or media.

Configuration
SNMP community strings allows you to set low-level security for an ORCA-4K
gateway. With a community string, you can assign a name to your ORCA-4K gateway. This name will be embedded in every header packet sent from the gateway.
When an ORCA-4K gateway and the Nuera NetConductor EMS have community
strings enabled, they will both embed the same name in their messages, verify the
name in the header and discard packets from nodes that do not contain the configured community string. The default community string is set to public. There are
two community string commands.
Manager Community Show
Display the current community string name listed for the ORCA-4K gateway with
the following command:
MANAGER COMMUNITY SHOW
Manager Community Write
The gateway supports community strings using the following parameters: <INDEX>
<PRIVILEGES> <STRING>. After entering the command below, a prompt will appear
to enter one of the following parameters:
<INDEX>
This parameter specifies one of five community strings where <INDEX> is 1,2,3, 4
or 5.
<PRIVILEGES>
This parameter grants read-only or read-write privileges to the gateway accessed
by the specified community string. Specify r or rw.
<STRING>
This parameter specifies the designation (name) for the ORCA-4K gateway. Specify a string of up to 32 alphanumeric characters.

TDM Connection Type Commands
The first command displays the current TDM Connection type (STM1, OC3, DS3). If
configuring an optical ORCA-4K, please use this command to confirm the gateway is
configured for the desired optical interface (STM1 or OC3):
TDMCONNTYPE SHOW
An optical ORCA-4K gateway is initially shipped with a TDM connection
type configuration of OC3. If you are using the ORCA-4K in an STM-1
application you will have to configure it for STM1.
The following command allows you to configure the current optical connection:
TDMOPTCONNTYPE [STM1/OC3]
Changing the optical connection type will cause a storage initialization (see
“Storage Initialization Command” on page 43 to be performed by the gateway.
When a DS3 daughter card is present in your gateway, this command will display an
error message and exit. When changing the optical connection type, you must power
cycle your system for changes to take affect.
VPMReset Command
The VPMRESET command allows the VPM board to be reset from the associated
port.
VPMRESET
Version Command
The version command displays the number and date of the Nuera ORCA-4K code
release currently running on the active VPM.

Quit Command
The quit command ends an ORCA-4K gateway Craft session and returns the display
to the Enter Password prompt. After a Craft session has ended, you must re-enter
the password to begin a new Craft session.
Always conclude a terminal session by executing the quit command. This prevents
accidental or unauthorized use of a command that might disrupt the operation of the
ORCA-4K gateway.
QUIT
Storage Initialization Command
The storage init command deletes all configuration settings (except the Ethernet
addresses) from the gateway and resets them to factory defaults. After entering this
command, you must confirm the action, then wait approximately 30 seconds until
another prompt appears requesting to power cycle the gateway.
STORAGE INIT
You must not power cycle the gateway until prompted. Power cycling too
soon can result in an undefined configuration, which can cause irreparable
damage to the gateway.

MAINTENANCE
This chapter presents maintenance procedures and techniques for working with the
the ORCA-4K gateway and its components. The VPM, BCM, OCM, DS3 Connector
Module, Alarm Module and fan tray are hot-swappable and serviceable outside the
chassis. The DSP Modules can be installed on a VPM after it has been removed from
the chassis. The DSP Modules cannot be hot swapped.
Precautions
Nuera does not recommend any maintenance on the internal components of the chassis. If, however, you must access the internal parts of the chassis, you should take the
following precautions:
•
Always disconnect the main power and any connections to the public telephone network.
•
Electrostatic Discharge (ESD): All internal assemblies and cable ports on the
rear panels are susceptible to damage from ESD. To reduce the possibility of damage to these devices, always observe standard ESD handling precautions, including (but not limited to) the following:
•
Avoid touching circuitry or conductive components of the gateway or its subassemblies without being properly grounded.
•
Place the gateway and all subassemblies on a grounded anti-static mat whenever maintenance is performed.
•
Use an approved personal grounding device (such as a wrist strap) at all times
when handling these products. To prevent rapid dissipation of any static
charge and to protect service personnel from electric shock, a minimum of
1MΩ (Megohm) series resistance is required between service personnel and
the ground connection. Please consult Nuera for additional information.
ORCA-4K Hardware Manual
44
Maintenance
•
Use only approved anti-static containers when shipping or moving any of
these products.
•
Failure to observe these precautions could result in serious damage to the
gateway modules with either immediate or latent operational failure or performance degradation. ESD-related failures due to improper handling may
affect the coverage under your warranty.
Gateway Status Monitoring
You can monitor the gateway operation in five ways:
•
Nuera NetConductor EMS
•
SNMP trap monitoring
•
Alarm port monitoring
•
Syslog Collector
•
LED indicators
VPM LED Indicators
The VPM includes three sets of LEDs. The first set (far left) indicates the overall system health, the second set (middle) indicates the status of the TDM interfaces, and
the third set (far right) indicates the status of the ethernet (100 Base-T and 1000
Base-SX) ports. These LEDs and their associated conditions are described in Tables
2, 3 and 4.
OCM LED Indicators
The OCM card has four bi-color LEDs: two on the far left and one on each side of the
Optical interface. On the left, a green LED signifies the Working interface, while a
yellow LED shows the Protect interface. The LEDs on each side of the optical interface provide link status information for the optical interface. A green LED signifies
that the OCM is receiving a signal, while an unlit LED signifies that no signal is
being received.
Fan Tray LED Indicator
The fan tray has a bi-color LED status indicator. Normal operation is designated by a
green LED. A red LED indicates there is a fault within the fan tray. If neither LED is
lit, the fan tray may have lost connection to power and should be replaced immediately. The fan tray also monitors both power feeds. Although only one feed is necessary to power the fan tray, the LED will remain red in this case to indicate a
potential for a single point of failure. For this reason, verify there are redundant

Maintenance
power inputs before servicing the fan tray This LED and the associated conditions
are described in Table 5.
Maintenance Procedures
Chassis Intake/Exhaust
Given the complexity of the internal circuitry of an ORCA-4K gateway, maintaining
operating temperatures within acceptable levels is critical. Cooling is provided by a
fan tray on the left side of the ORCA-4K gateway. Ensure that the air intake and
exhaust areas are not obstructed during operation.
Hot-Swapping a Fan Tray
If you receive a fan tray failure notification, either through the Nuera NetConductor
EMS or by observing the LED’s, remove the faulty fan tray after confirming the
redundant power inputs are connected, then insert a new fan tray into the chassis.
No tools are required to perform this task.
Removing an ORCA-4K gateway fan tray alters the airflow characteristics
of the chassis. Operating a gateway in this condition will cause overheating.
To avoid potential damage or loss of service, ensure the fan tray is replaced
as quickly as possible. The system should not be run (at ambient temperature) without a fan tray any longer twenty minutes.
VPM Installation
Follow the steps below to install a VPM.
To install a VPM card:
1. Ensure the black ejector tabs on the front of the VPM are in the unlocked/open
position by pushing the red tabs outward.
2. Ensure the DSP module ejector tabs on the right side of the circuit card are in the
closed (towards the center of circuit card) position.
3. Place the bottom edge of the circuit card into the card guide slot. The edge of the
module must be inserted into the channel to ensure alignment with the midplane
connectors.
4. Carefully slide the front module all the way into the chassis.
5. Close/lock the ejector handles to fully seat the module to the midplane connectors.
There will be an audible “click” when the red tabs on the handles are closed.
ORCA-4K Hardware Manual

Maintenance
6.
Tighten the captive screw on both ejector handles to the chassis.
Hot Swapping a VPM
Once you have received notification of a VPM failure, use the following procedure to
remove the faulty VPM and insert a new one into the chassis.
To hot-swap a VPM card:
1. Unscrew the captive screws located on either side of the ejector handles.
2. Push the red tabs outward to unlock the ejector handles; then pull the handles to
disengage the circuit card from the midplane connectors.
3. Remove the VPM from the chassis by gently pulling on the ejector handles.
4. To install the new VPM, see "VPM Installation" on page 46.
Swapping a VPM Between Gateways
Swapping VPM cards between 4K gateways can alter the gateway configuration and
cause IP conflicts in your network. To prevent potential problems, Nuera recommends that you only insert a VPM from one gateway into another gateway containing
a VPM that has already reached the active state (as detailed in Scenario 1).
Scenario 1: Gateway with Active VPM
If a VPM from one gateway is inserted into a gateway with an existing active VPM,
the new VPM will arbitrate to standby mode in the new gateway. It will receive background IP addresses and mirrored configuration from the active VPM card. In this
way, the new standby VPM will take on the configuration of its new gateway.
Scenario 2: Gateway with no Active VPM
If a VPM from one gateway is inserted into an empty chassis, it will arbitrate with
the other VPM (if inserted at the same time) to decide which card should become
active. There is no easy way to determine which VPM will decide to become active
and thus which configuration and IP addresses will be used. If the VPM arbitrates to
active mode in the new gateway, it will maintain the floating IP address it had in the
previous gateway. This may cause a problem if was the standby card in the previous
gateway because now two gateways in the network will have the same IP address. To
resolve this problem, use craft port commands to reconfigure the VPM.
ORCA-4K Hardware Manual
47
Maintenance
DSP Module Installation
To install a DSP Module:
1. Remove the VPM from the chassis as directed in the procedure “Hot Swapping a
VPM” on page 47 and place it on a firm surface.
2. Open the DSP card guide ejectors located on the VPM. Always install the DSP
module in sequential order (start with Slot 1 then Slot 2, then Slot 3 etc....); do not
skip slots.
3. Carefully place the DSP module into the connector slot and gently push down
until the ejector handles snap in place.
4. Ensure that all non-populated DSP connector ejectors are in the closed (up) position before re-installing the VPM into the chassis. Failure to confirm this may
result in a broken ejector handle during installation of the VPM into the chassis.
OCM Card Installation
Follow the steps below to install an OCM module.
To install an OCM card:
1. Place the bottom edge of the circuit card into the card guide slot. The edge of the
module must be inserted into the channel to ensure alignment with the midplane
connectors.
2. Carefully slide the module all the way into the chassis.
3. Tighten the captive screws on both sides of the module to the chassis.
OCM Card Removal (Hot Swap)
Once you have received notification of an OCM failure, use the following procedure to
remove the faulty OCM card and insert a new one into the chassis.
To hot-swap an OCM card:
1. Unscrew the captive screws located on either side of the ejector handles.
2. Remove the OCM card from the chassis by gently and evenly pulling on the handle or the captive screws.
3. See "OCM Card Installation" on page 48 to install the new OCM card.
ORCA-4K Hardware Manual
48
Maintenance
Rear Module Installation and Removal (Hot Swap)
There are no card guides for the rear modules. They are installed “blind mated” to the
appropriate card edge connector on the midplane.
To hot-swap rear modules:
1. Once the module is inserted into the midplane connector, tighten the fastener
screws on the front panel using a equal number of turns on each fastener until the
module is fully seated.
2. The rear modules can be hot swapped and replaced by equally rotating the fastener screws counterclockwise until the threads are no longer engaged with the
chassis, then the module can easily be removed and replaced.
Gateway Upgrades
Upgrading an ORCA-4K gateway requires the use of the Nuera NetConductor EMS
and the procedures located in the ORCA-4K Application Manual and release notes on
the Nuera Software CD. These items are shipped with each upgrade and can also be
downloaded from the Nuera Technical Assistance Center website.
