ESD Safety

To protect the delicate Acme Packet 4500 electronic components from damage from
static electricity, always follow the appropriate ESD procedures and wear the proper
protective devices (such as an ESD wrist strap) when handling any and all Acme
Packet 4500 hardware and while performing any Acme Packet 4500 hardware
procedures.

Precautions To protect your equipment from ESD, follow these ESD safety precautions:

• Ensure that the Acme Packet 4500 is properly grounded.

• If you are grounding your Acme Packet 4500 to an electrically conductive,

grounded rack, check to see whether or not the rack is painted. Paint can hinder
proper grounding. If your equipment rack is painted, you should ground the
system to some other reliable place or remove a small portion of paint for proper
grounding.

• Use a grounded ESD wrist strap when working on the Acme Packet 4500 to

prevent static discharge.

• To avoid damaging ESD-sensitive hardware, discharge all static electricity from

your body before working directly with the Acme Packet 4500 chassis by
touching a grounded object.

Without powering down the Acme Packet 4500, you can exchange an NIU (for the
same type of card) by removing and replacing it. Upon NIU removal, the Acme
Packet 4500 enters an Out-of-Service state. After you reinsert the NIU and connect
to the ACLI, you must reboot the system to return to service. This causes a soft­reboot rather than a system power cycle.

Console Port The console port on the NIU provides console access to the Acme Packet 4500 over

a RS-232C serial connection. The Acme Packet 4500 supports only one active serial
console connection at a time. The rear console port is useful for customers who want
permanent console access; the front console port provides easy access to the Acme

Alarm Port The alarm port on the NIU is a flexible interface that closes a circuit when a specific

alarm level becomes active on the Acme Packet 4500. The Acme Packet 4500 features
an alarm control signal interface that can be used in a CO location to indicate when
internal alarms are generated. The Acme Packet 4500 uses alarm levels that
correspond to three levels of service-disrupting incidents. When any of the three
alarm levels is generated, the corresponding circuit for that level on the alarm port is
closed.

• RADIUS CDR transmission

It is recommended that you use shielded CAT5e or CAT6 Ethernet cables with RJ45
plugs for connecting to the rear-panel Acme Packet 4500 Ethernet interfaces. These
Ethernet interfaces have a distance limitation of 328 feet (100 m), as defined by the
FAST Ethernet standard, IEEE 802.3.

Signaling and Media Interfaces

Power Components

The signaling and media interfaces provide network connectivity for signaling and
media traffic. Each interface can connect to a network at GbE speeds. Network
interface and hardware options differentiate the available NIU cards for order.

NIUs are available in the following configurations:

• 4-port 10/100/1000Mbps Copper (RJ45)

• 4-port GbE SFP (LX, SX, or Copper) [1000Mbps for SX, LX; 10/100/1000Mbps

CX]

• 4-port GbE SFP with QoS and IPsec (LX, SX, or Copper)

• 4-port GbE SFP with IPsec (LX, SX, or Copper)

The optical GbE cards can accept an LC fiber connector using either single mode or
multimode cable.

Mixed transceiver types are unsupported on SFP-based NIUs; all 4 ports are required
to be populated with identical SFPs, based on compliance testing.

The Acme Packet 4500 offers AC or DC power options for the Acme Packet 4500.
The power supplies are user-replaceable, hot swappable components.

Power Supply Redundancy

During normal operation, the Acme Packet 4500 is load-balanced and draws power
from both supplies. The two power supplies also provide hardware redundancy. If a
power supply fails, the Acme Packet 4500 can rely on only one functional power
supply to sustain normal operation. A malfunctioning power supply must be
removed and replaced as soon as possible. If the Acme Packet 4500 starts up with
only one power supply, it will not generate an alarm.

AC Power The auto-sensing AC power supply is rated at 110-240 VAC, 50-60 Hz, and comes

with an IEC connector. You insert and remove the power supply from the system
chassis by its handle. Use the locking screw to lock the power supply into the chassis.

COMPONENT OVERVIEW

Acme Packet4000 Series Hardware Architecture

The hardware architecture of the Acme Packet4000 series hardware architecture is
depicted below. The Acme Packet4000 series hardware is purpose built for SBC
applications and relies on state-of-the-art network processing and traffic
management components to deliver the necessary platform for delivering security
and scalable media processing.

The Network Processing (nP) subsystem is comprised of the network processors,

raffic management, and content addressable memory (CAM). This subsystem hosts

t
the media control module and is completely hardware based. Adjunct to the network
processing components are the QoS engine for monitoring bearer QoS metrics.

The signaling processor subsystem is c

omprised of the host subsystem and
associated memory (noted in red in the diagram). The session control functions
including the session signaling layer, call routing and management elements are
hosted on the signaling processor subsystem.

The separation of signaling and media proce

ssing is absolutely necessary for the

following reasons:

• Guarantee medi

a processing will never overwhelm signaling processing.
Signaling processing performance is not impacted by media processing load as
it is with single more monolithic solutions based on general purpose computing
platforms.

• Pro

tection of the signaling processing subsystem for overload and DoS attacks.
When DoS attacks are detected, these attacks are policed and isolated in
hardware.

The following architectural diagram is a lo

gical representation of the Acme
Packet 4500. The Acme Packet 4500’s Network Processor is physically one
device.

SYSTEM INSTALLATION

Pre-Installation

Caution The Acme Packet 4500 shall only be installed in a restricted

access location.

The Acme Packet 4500 must have access to reliable power and cooling. When
choosing a location for your Acme Packet 4500, follow the guidelines listed in this
section.

Environmental Guidelines

When preparing to install your Acme Packet 4500:

• Ensure that the equipment rack location complies with the specifications

detailed in the Environmental Specifications section of the Specifications chapter of
this guide.

• Locate the Acme Packet 4500 in a clean and well-ventilated room. This location

should also be far from areas where heat, electrical noise, and electromagnetic
fields are present.

Power Guidelines When preparing to install your Acme Packet 4500:

• Ensure that the installation location has access to adequate power and

grounding. Separate circuits should be available for each of the Acme Packet
4500 power supplies.

• Acme Packet 4500s may only be powered by AC or DC circuits at one time;

mixed power configurations are unsupported.

• Never use extension cords when powering a Acme Packet 4500.

• Use grounded, three-conductor circuits.

• A local earth ground must be available.

Caution Connect each of the Acme Packet 4500 power supplies to a

separate circuit. If both supplies are connected to outlets on
the same circuit, the Acme Packet 4500 will lose power to
both supplies if that circuit loses power. In that case, the whole
Acme Packet 4500 would lose power.

Mounting Guidelines

Other Safety Guidelines

When preparing to install the Acme Packet 4500, follow these mounting guidelines:

• Leave enough clearance (approximately 8” (20 cm)) in front of the equipment

rack to allow access to the console connector, reset button, graphic display
buttons, and physical interface card slots.

• Leave enough clearance (approximately 4” (10 cm)) in the rear of the equipment

rack to allow for sufficient airflow and for ease in cabling and/or servicing the
rear panel.

• Do not block the air inlets or the fan module, or obstruct airflow to the system

in any way.

• Position equipment to allow for serviceability. This will aid in chassis removal

and prevent the need to remove or loosen other equipment in the rack.

• Remember that the Ethernet interfaces are limited to 328 feet/100 meters as

defined by the FAST Ethernet standard, IEEE 802.3.

• Use the contents of the Slide Extender Kit for cabinet-style, 4-post equipment

racks that range in depth from 28” - 32”.

When preparing to install your Acme Packet 4500:

• Review the precautions detailed in the Safety chapter of this guide before

beginning installation.

• Ensure that the equipment rack is securely bolted to the floor, and that the

equipment rack and components are properly grounded.

• For AC power installations, use a regulating UPS to protect the Acme Packet

4500 from power surges, voltage spikes, and power failures.

For AC power installations, ensure that your UPS can supply power for enough time
to save your system data and shut down the system gracefully.

You can install and remove Ethernet and GbE optical cables while the Acme Packet
4500 is operational. Not every port needs to be utilized for proper operation.
However, when a cable is disconnected and the link is lost, an alarm is generated.

Warning: The intra-building ports of this equipment are suitable for
connection to intra-building or unexposed wiring or cabling only. The
intra-building ports of the equipment must not be metallically
connected to interfaces that connect to the Outside Plant (OSP) or
its wiring. These interfaces are designed for use as intra-building
interfaces only (Type 2 or Type 4 ports, as described in GR­1089–CORE, Issue 6) and requires isolation from the exposed OSP
cabling. The addition of primary protectors is not sufficient protection
to connect these interfaces metallically to OSP wiring.

Note: Intra-building ports include Media and Signaling Network Interfaces,
Network Management Ports, Alarm Ports, and Console Port.

Console Port Note: Intra-building ports include Media and Signaling Network Interfaces,

Network Management Ports, Alarm Ports, and Console Port.

The Acme Packet 4500 has two console ports, one mounted on the chassis front
control panel and the other mounted on the rear-facing NIU. The Acme Packet 4500
ships with a console adapter that allows you to connect a standard DB-9 serial port
to the Acme Packet 4500 RJ45 console port. Only one console port on the Acme
Packet 4500 can be used at a time.

The console port located on the front panel is the default. This may be changed by
configuration. Only one console port on the Acme Packet 4500 can be used at a time.
Some text may be output to the non-active console port. This is normal. However,
only input from the active console port can be recognized by the Acme Packet 3820.

Note: For bootloaders dated November 10, 2010 and later, on initial
boot, if the rear console port is connected, a message is displayed
instructing you to reconnect to the front console port.

Introduction

This chapter explains Acme Packet 4500 hardware maintenance procedures. This
chapter also provides hardware alarm information.

System Shut Down

Although several user-replaceable components of the Acme Packet 4500 are hot­swappable, some Acme Packet 4500 maintenance procedures require that you shut
down the system.

Before you shut down or restart the Acme Packet 4500, ensure that there are no
active calls in progress. Procedures to reroute call and network traffic around the
Acme Packet 4500 are outside the scope of this guide.

You can set the Acme Packet 4500 to reject all incoming calls from your system with
the set-system-state command. When set to offline, this command lets calls in
progress continue uninterrupted, but no new calls are admitted.

Rejecting Incoming Calls

Shutting down the Acme Packet 4500

After all call processing has stopped, you can power off your Acme Packet 4500.
Shutting down the system is appropriate when you are replacing a physical interface
card, power supply, or are removing the Acme Packet 4500 from the equipment rack.

To reject all incoming calls on the Acme Packet 4500:

1. In Superuser mode, type set-system-state offline and press <Enter>.

ACMEPACKET# set-system-state offline
Setting system state to going-offline, process will complete when all

current calls have completed
ACMEPACKET#

After all call processing has stopped, you must halt the operating system before you
power off your Acme Packet 4500 when running S-CZ software images. Shutting
down the system is appropriate when you are replacing a physical interface card,
storage device, power supply, or are removing the Acme Packet 6300 from the
equipment rack.

1. In superuser mode, type halt and then press <Enter>, then answer y followed

by <Enter> at the halt confirmation prompt.

Confirm that the graphic display is dark and all fans are off. You can now unplug the
Acme Packet 4500 from its power supply and continue with maintenance
procedures.

Rebooting, Resetting, and Power Cycling

Reboot Rebooting the Acme Packet 4500 shuts down the system in an orderly fashion and

then starts it up again. The operating system gracefully shuts down as processes are
terminated and the file system is stopped. While the system and its processes are
stopped, all call processing is immediately halted. You may therefore wish to
perform tasks that call for a reboot during off-peak maintenance hours.

Rebooting the Acme Packet 4500 is required

every time you upgrade with a new

version of the Acme Packet 4500 software.

Before rebooting the Acme Packet 4500, save your

configurations. Refer to the
Maintenance and Troubleshooting Guide for a full explanation of this procedure. The
save-config command is used to save the configuration in the example below.

For a full explanation and all options for the reb

oot command used in the example

below, refer to the ACLI Reference Guide.

To reboot the Acme Packet 4500:

1. Save any configuration changes you have made in

the ACLI by typing save-

System Reset Resetting the Acme Packet 4500 via the front of the chassis performs a cold reboot.

This is the equivalent to disconnecting the power from the system and then
reconnecting it. There is no orderly termination of tasks, and the system shuts down
abruptly. You should only reset the Acme Packet 4500 when it becomes unstable and
no other means of gaining administrative control is possible.

During a system reset, certain files are not

closed properly, and they may become
corrupted. Depending on what files become damaged, the system might become
completely unusable.

Caution Always try to first reboot the Acme Packet 4500 from the ACLI

before performing a cold reset. Only reset the system as a last
resort.

To reset the Acme Packet 4500:

1. Insert a rigid paperclip-sized tool into t

he small hole on the front of the chassis

beneath the graphic display.

Figure 6 - 94. Reset Button

The system immediately resets and begins its initialization and boot sequence.

Power Cycling Power Cycling the Acme Packet 4500 is the process of turning the chassis off then

on from the switches on the power supplies or by equivalent means to remove power

Acme Packet 4500 Hardware Installation and Maintenance Guide 71

MAINTENANCE

from the system. It is imperative that you wait at least 10 seconds between power
down and power up to ensure that all components are completely powered down
before restart.

Power cycling the Acme Packet 4500 without performing a halt operation can lead
to data loss to the Storage Device when running S-CZ software images. To ensure
stable operation a file system check will be performed on the next power up. This
check may take several minutes to complete, and should not be interrupted.

Standby Mode for HA Nodes

When performing hardware maintenance on the Acme Packet 4500, it is best to
minimize any risk of interrupting network traffic or losing data. If the Acme Packet
4500s are configured as an HA node, you should only work on the Acme Packet 4500
that is in standby mode.

There are two ways to determine the HA state of each Acme Packet 4500 in an HA
pair.

1. If you are in the same physical location as the Acme Packet 4500s, you can view

the graphic display on the front panel. The display will indicate HA state as
explained in the Graphic Display Output for HA Nodes section of the Graphic
Display chapter of this guide. There is no (S) designation for an active system,
but there is for a standby system.

2. If you are not in the same physical location as the Acme Packet 4500s, you can

use the ACLI show health command. The output of this c ommand indic ates the
current HA state of the Acme Packet 4500.

Once you have determined that the Acme Packet 4500 due for maintenance is in
standby mode, you can continue with the appropriate procedures to replace a part.

If you need to perform maintenance on the active Acme Packet 4500, you need to
manually force the two Acme Packet 4500s to switch HA states. Forcing a switchover
renders the currently active Acme Packet 4500 standby, and the currently standby
Acme Packet 4500 will assume all traffic processing and forwarding as the active
system.

Caution This procedure is only applicable to Acme Packet 4500s in an

HA deployment.

Power Supply Removal and Replacement

This section explains how to remove and replace the power supplies in the Acme
Packet 4500 chassis.

Caution When removing or replacing a single power supply in a running

chassis, ensure that its power switch is turned off first. Failure
to turn off the power supply switch before insertion or removal
may damage the system.

After physically switching off a power supply, disconnect it
from the power source before you remove or install it in the
chassis.

Caution Both power supplies must be the same type AC or DC. The

power supplies must be populated with two identical power
supplies made by the same vendor. The vendor is identified by
the label on top of the power supply.

AC or DC Power Supply Removal

The power supply is a user-replaceable component. If a Acme Packet 4500 power
supply malfunctions, you should remove the malfunctioning power supply and
replace it. The power supply can be removed from the chassis while still installed in
the rack and while the second power supply is providing system power; this is called
a warm swap. When removing and replacing a power supply, remember to first
ground yourself using appropriate ESD grounding equipment such as a wrist or heel
strap.

Note: See Power Components for an explanation about power supply
numbering.

For information regarding how to obtain a replacement power supply, contact your
Acme Packet customer support representative directly or E-mail
[e-mail].

You can remove AC and DC power supplies with the same procedure once they are
disconnected from their power source. The images used in the procedure below use
an AC power supply.

Note: You can have the system up and running during this procedure
if you are changing out a defective power supply.

1. The system is up and running.

2. Locate the defective power supply.

3. Turn the power switch to the OFF position on the defective power supply only.

4. Follow the procedure below.

The Acme Packet 4500 air filter removes airborne particles before they are drawn
into the Acme Packet 4500 chassis. To prevent system malfunction and prolong the
life of the system cooling components, follow these guidelines:

• Clean or

replace the air filter every three months.

• Clean the air inlets once a week.

Cooling maintenance encompasses cleaning the fan

module and cleaning the air
inlets on the front of the Acme Packet 4500 chassis. Cleaning the fan module
requires that you remove the module itself. If you are not shutting down the Acme
Packet 4500, this procedure must be performed quickly; otherwise, the system may
overheat and cause packet processing to stop.

This maintenance should be performed alongside other preve

ntative maintenance to
take place within a planned maintenance or downtime window, during off-peak
hours.

NIU Removal and Replacement

When possible, remove system power before removing and replacing an NIU.
However, without powering down the Acme Packet 4500, you can exchange an NIU
(for the same type of card) by removing and replacing it. Upon NIU removal, the
Acme Packet 4500 enters an Out-of-Service state. After you reinsert the NIU and
connect to the ACLI, you must reboot the system to return to service. This causes a
soft-reboot rather than a system power cycle.

Caution Make sure you are properly grounded with an ESD strap before

removing the NIU.

NIU Removal To remove an NIU:

1. Unplug all network and management cables from the NIU you plan to remove

from the Acme Packet 4500 chassis.

Note: This will cause a link loss on all connections.

Acme Packet 4500 Hardware Installation and Maintenance Guide 83

2. Unscrew the two thumbscrews located on each side of the NIU with a #2 Phillips

screwdriver. The screws are spring-loaded and will push forward, but they will
not fall out of the NIU.

Figure 6 - 114 . Loos e ning Thumbscrews

3. Pivot the two ejection levers outward at the same time, pulling the card out of

its connection to the motherboard and away from the system chassis. This action
disengages the NIU from the system, severing all electrical contact to the
