2 Acme Packet 3900 Component Overview
Chassis
Please find complete installation instructions in Chapter 3 Unit Installation. This chapter includes cabling information for the Acme Packet 3900.
The Acme Packet 3900 is contained in a 1U rack-mounted chassis. It can be front- or center-mounted in standard 19” wide racks (up to 28” deep), with options for 23” wide racks.
Figure 2 - 1. Acme Packet 3900 - Front Panel
Figure 2 - 2. Acme Packet 3900 - Rear Panel
Mounting
Hardware
Equipment Rack
Installation Hardware
The Acme Packet 3900 is supported by a pair of cabinet slides that are affixed to an equipment rack by front and rear mounting flanges. The cabinet slides are adjustable for equipment racks of various depths.
For equipment rack installations, the chassis must be outfitted with left and right chassis-mounted slide rails. One rail is secured to each side of the chassis, that slides into another rail that is attached to the inner posts on both sides of the equipment rack. This two-piece mounting simplifies chassis installation and removal.
When installing the chassis, the user can easily slide the chassis along the slide rails until a locking clip on each chassis-mounted rail locks the chassis into the slide rails.
Pressing this clip will then allow the chassis to be fully installed into the equipment rack. Once inserted into the equipment rack, the Acme Packet 3900 is secured in place with two captive thumbscrews.
The locking clip is also a safety mechanism for removing the chassis from the equipment rack. When removing the chassis, the locking clip engages to prevent the
11
Acme Packet 3900 Hardware Installation and Maintenance Guide
chassis from being overextended and requiring the user to unlock the clip to intentionally remove the chassis.
Figure 2 - 3. Slide Rail Locking Clip
•
The slide rails that are bolted to either side of the chassis or equipment rack are reversible and can be used on either side of the Acme Packet 3900.
12
Figure 2 - 4. Rack-Mounted Slide Rail (rear mounting point at left)
Figure 2 - 5. Chassis-Mounted Slide Rail
•
Once the slide rails are installed on the chassis and on the equipment rack, the chassis can be installed in the rack by inserting the chassis slide rails into the tracks of the slide rails already mounted on the equipment rack. When the locking clip latch on the chassis slide rail meets the hole in the rack slide rail, the rails lock together. Push the locking latch in to continue to slide the chassis into the rack rails.

T1/E1 Ports
In centralized SIP trunking topologies, this T1/E1 module preserves voice services in the event of a corporate WAN connectivity failure. In distributed SIP trunking topologies the module preserves dialout voice services in the event of a local SIP trunk interface failure.
The RJ48C connector looks very similar to an RJ45 connector found on a typical
CAT5 cable, but they are very different. A RJ48C connector is fastened on to a STP
(Shielded Twisted Pair) cable, not the standard UTP (Unshielded Twisted Pair) CAT-
(1-6) cable. A RJ48C connector also uses a different pin out arrangement, voltage level, and line capacitance than a RJ45 connector.
Serial
Management Port
The serial management port on the Acme Packet 3900 rear panel the provides console access to the unit over an RS-232C serial connection. The serial management port is useful for customers who want permanent console access, and provides a layer of physical security for the unit if access to the site is controlled.
Console port communication is used for administration and maintenance purposes from a central office (CO) location. Tasks conducted over a console port include:

Acme Packet 3900 Hardware Installation and Maintenance Guide
Cabling the Acme Packet 3900 System
After mounting the Acme Packet 3900 in an equipment rack and installing all components into the chassis, connect all appropriate data cables to the ports before powering the unit up and configuring it.
Oracle recommends using fully shielded CAT5e or CAT6 Ethernet cables for media and management Ethernet connections to protect the Acme Packet 3900 from potential damage.
You can install and remove Ethernet and GbE optical cables while the Acme Packet
3900 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.
Console Port
Warning: The intra-building ports of the 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 GR-1089–
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.
The Acme Packet 3900 has one console port located on the chassis rear panel. The
Acme Packet 3900 ships with a console adapter that allows you to connect a standard
DB-9 serial port to the Acme Packet 3900’s RJ45 console port. Only one console port on the Acme Packet 3900 can be used at a time.
Figure 3 - 61. Serial Management Port

Chassis Serial
Management Port
Cabling Procedure
This section explains how to create a serial connection to the Acme Packet 3900 console port. Use the serial management port for permanent connections to a terminal server or other serial device.
To connect a cable to the serial management port:
1.
Locate a twisted pair cable to connect to the Acme Packet 3900.
2.
Remove the rubber dust cap from the Chassis console port if present.
3.
Insert the RJ45 connector on the end of the cable into the serial management port. The release tab on the RJ45 jack clicks into place when you insert it properly.
4.
Lead the cable neatly away from the rear panel toward a terminal server or other component where this serial connection terminates.
Cabling the T1/E1 Port
If you have purchased the optional four port T1/E1 interface module for TDM, you must cable the T1/E1 port(s). In centralized SIP trunking topologies this module preserves voice services in the event of a corporate WAN connectivity failure. In distributed SIP trunking topologies the module preserves dialout voice services in the event of a local SIP trunk interface failure.
Note: The RJ48C connector looks very similar to an RJ45 connector found on a typical CAT5 cable, but they are very different. A RJ48C connecter is fastened on to a STP (Shielded Twisted Pair) cable, not the standard UTP (Unshielded Twisted Pair) CAT-(1-5) cable. A RJ48C also uses a different pin out arrangement, voltage level, and line capacitance then a RJ45.
This section explains how to create a physical T1 or E1 connection to the Acme
Packet 3900 T1/E1 port. Use the top rear bank of ports marked T1/E1 for a permanent connection to Wide Area Network (WAN).
Figure 3 - 62. T1/E1 Ports
To connect T1 or E1 cable to the WAN port:
1.
Insert the RJ48C connector(s) on the end of the T1/E1 cable(s) into the port(s) labeled T1/E1.
2.
Lead the cable(s) neatly away from the rear panel toward the component where this connection terminates.

5 Maintenance
Introduction
This chapter explains Acme Packet 3900 hardware maintenance procedures.
Although most user-replaceable components (also called Field Replaceable Units or
FRUs) of the Acme Packet 3900 are hot-or warm-swappable, some limited Acme
Packet 3900 maintenance procedures require that you shut down the system.
Examples of maintenance procedures which require you to shut down the unit include:
•
Removing the unit from the equipment rack for any reason
• Removing the cover from the chassis
•
Replacing transcoder DSP modules
• Replacing the T1/E1 TDM card.
General Caveats for Acme Packet 3900 maintenance:
•
Always observe correct ESD procedures.
• Before you start any maintenance procedure which includes parts replacement, make sure you have the correct part on-hand. Any user-replaceable components may be ordered in advance from Oracle.
•
Oracle recommends stocking replacement parts for:
• Air filters
•
Fans
• Power supplies
•
Optical Transceivers
• DSP modules

Unit Shutdown
Before you shut down or restart the Acme Packet 3900, ensure that there are no active calls in progress. The command to show active calls is “show sessions.”
ACMEPACKET# show sessions
Procedures to reroute call and network traffic around the Acme Packet 3900 are outside the scope of this guide.
You can set the Acme Packet 3900 to reject all incoming calls from your unit with the
ACLI set-system-state command. When set to offline, this command lets calls in progress continue uninterrupted, but no new calls are admitted.
After all call processing has stopped, you can power off your Acme Packet 3900.
Shutting down the unit is appropriate when you are replacing a power supply or are removing the Acme Packet 3900 from the equipment rack.
Rejecting
Incoming Calls
To reject all incoming calls on the Acme Packet 3900 System:
1.
In Superuser mode, type show sessions to see all the current calls.
ACMEPACKET# show sessions
2.
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#
Shutting Down the
Acme Packet 3900
System
To shut down the Acme Packet 3900 hardware:
1.
In Superuser mode, type halt and then press <Enter>.
2.
To confirm the halt request, type Y and then press <Enter>.
3.
When the console indicates shutdown is completed, unplug the AC power cords from the power supplies on the rear panel of the Acme Packet 3900.
4.
Confirm that all fans are off.
Rebooting, Resetting, and Power Cycling
Reboot
Rebooting the Acme Packet 3900 shuts down the unit in an orderly fashion and then automatically restarts it. 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 3900 is required every time you upgrade with a new version of the Acme Packet 3900 software.
Save your configurations before rebooting the Acme Packet 3900. 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.
56
Acme Packet 3900 Hardware Installation and Maintenance Guide
System Reset
Caution
For a full explanation and all options for the reboot command used in the example below, refer to the ACLI Reference Guide.
To reboot the Acme Packet 3900:
1.
Save any configuration changes you have made in the ACLI while in Superuser mode by typing save-config <Enter>.
ACMEPACKET# save-config

2.
Execute the reboot command at the Superuser prompt by typing reboot and then pressing <Enter>.
ACMEPACKET# reboot
-----------------------------------------
WARNING: you are about to reboot this SD!
3.
Type Y and then press <Enter> at the confirmation prompt to proceed with the reboot.
Reboot this SD [y/n]?: y
Resetting the Acme Packet 3900 via the reset pushbutton on the right rear of the chassis panel performs a cold reboot. This action is the equivalent of disconnecting the power from the unit and then reconnecting it. There is no orderly termination of tasks, and the unit shuts down abruptly. You should only reset the Acme Packet 3900 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. If an unclean shutdown is detected, file system recovery/repair will be run to ensure the system returns to a stable state. File system verification also runs every
30 boots as a precautionary measure.
Always try to first reboot the Acme Packet 3900 from the ACLI before performing a cold reset. Only reset the unit as a last resort.
Acme Packet 3900 Hardware Installation and Maintenance Guide
57
To reset the Acme Packet 3900:
1.
Insert a rigid paperclip-sized tool into the small hole on the rear bottom of the chassis, between the USB ports and the Signaling and Media ports. The system immediately resets and begins its initialization and boot sequence.

Power Cycling the Acme Packet 3900 is the process of turning the chassis off and then on again. You can do this by pressing the power pushbutton on the front right bezel. When power cycling, 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 restarting the system.
Figure 5 - 70. Power Pushbutton
Standby State for High Availability Nodes
When performing hardware maintenance on the Acme Packet 3900, it is best to minimize any risk of interrupting network traffic or losing data. If the Acme Packet
3900s are configured as High Availability (HA) nodes, you should only work on the
Acme Packet 3900 that is in Standby state.
There are two ways to determine the HA state of each Acme Packet 3900 in an HA pair.
1.
If you are in the same physical location as the Acme Packet 3900 you can view the HA LEDS on the front bottom right. A standby unit lights the STBY LED, while an active unit lights the ACT LED.
58
2.
If you are not in the same physical location as the Acme Packet 3900, you can use the ACLI show health command. The output of this command indicates the current HA state of the Acme Packet 3900. See Figure 5-3 for examples.
Acme Packet 3900 Hardware Installation and Maintenance Guide
Caution
Once you have determined that the Acme Packet 3900 due for maintenance is in standby state, you can continue with the appropriate procedures to replace a part.
If you need to perform maintenance on the active Acme Packet 3900 you need to manually force the two Acme Packet 3900s to switch HA states. Forcing a switchover renders the currently active Acme Packet 3900 in Standby state, and the current standby Acme Packet 3900 will assume all traffic processing and forwarding as the active system.
This procedure is only applicable to Acme Packet 3900 in an
HA deployment.
To force a Acme Packet 3900 into the standby HA state:
1.
Confirm that the relevant Acme Packet 3900 systems on active and standby are synchronized with the show health command. Type show health and press
<Enter> on each unit as shown in the following.

Preparing the Acme Packet 3900 for Maintenance
The Acme Packet 3900 was designed so that it is not necessary to remove the chassis from the equipment rack for maintenance if there is adequate room to access the chassis for the desired procedure. The chassis cover is secured by the two thumb screws on the rear panel of the chassis.
Note: Any time you are going to remove the cover from the Acme
Packet 3900 for maintenance (for example, if you are going to replace a faulty DSP or T1/E1 TDM module), be sure to gracefully power down the system, then remove the power cords. You must also ensure that you are grounded before you remove the chassis cover.

Maintenance Procedures that do not require powering down the system
You can perform these maintenance tasks without powering down the Acme Packet
3900 system:
• Clean air inlets in the front left bezel
•
Replace air filters
• Clean fan modules
•
Remove and replace individual fans
• Remove and replace power supplies
•
Remove and replace optical transceivers
Maintaining the
Cooling
Components
The Acme Packet 3900 air filter removes airborne particles before they are drawn into the Acme Packet 3900 chassis. To prevent unit malfunction and prolong the life of the unit’s cooling components, do these things:
• 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 3900 chassis. Cleaning the fan module requires that you remove the module itself. If you are not shutting down the Acme
Packet 3900, this procedure must be performed quickly or else the unit may overheat and cause packet processing to stop.
This maintenance should be performed alongside other preventive maintenance to take place within a planned maintenance or downtime window, during off-peak hours.

Acme Packet to configure, maintain, and monitor Acme Packet SBCs and other
Acme Packet products.
AC — Alternating Current refers to the 120-volt electricity delivered by power utilities to three-pin power outlets. This type of power is called “alternating current” because the polarity of the current alternates between plus and minus, 60 times per second.
AWG — American Wire Gauge is a United States standard set of non-ferrous wire conductor sizes. The gauge means the diameter.
DC — Direct Current refers to the flow of electrons in one direction within an electrical conductor, such as a wire.
ESD — Electrostatic Discharge is the rapid discharge of static electricity from one conductor with an electrical charge to another of a different electrical charge.
CE — European Compliance
EN — European Norm
FG — Frame ground
Flash memory — Flash memory is a solid-state, non-volatile, rewritable memory that functions like a combination of RAM and a hard disk drive.
FQME — Flow Quality Measurement Engine is responsible for monitoring, measuring, and maintaining statistics (e.g., latency, jitter, flow stoppage, flow creation, etc.) on a flow-by-flow basis.
1GbE — Gigabit Ethernet is an Ethernet type that supports data transfer rates of 1 gigabit per second.
10GbE — 10GbE is an Ethernet type that supports data transfer rates of 10 gigabits per second.
IEEE — Institute of Electrical and Electronics Engineers is an organization composed of engineers, scientists, and students. The IEEE is best known for developing standards for the computer and electronics industry.

LOS — Loss of Signal occurs when the signal level falls below an acceptable level.
LOS is a physical layer error and typically results in an alarm.
NVRAM — Non-volatile Random Access Memory is a type of memory that retains its contents when power is turned off.
Optical Transceiver — The fiber connection to the Acme Packet 3900 plugs into an optical transceiver. Through this connection, light energy is converted into electrical energy.
PCMCIA — Personal Computer Memory Card International Association is an organization consisting of approximately 500 companies that has developed a standard for small, credit-card sized devices (PC cards). This standard is designed for attaching input/output devices such as network adaptors, fax/modems, or hard drives to notebook computers.
Physical Interface Card — The physical interface card is synonymous with the network interface cards on the Acme Packet 3900 System.
PROM — Programmable Read-only Memory is a memory chip on which data can only be written once. A PROM is non-volatile; it is a memory chip on which data can be written only once.
QoS — Quality of Service is a networking term that refers to the capability of a network to provide better service to selected network traffic over various technologies.
RAM — Random Access Memory is a type of computer memory that can be accessed randomly. RAM is the same as main memory.
RS-232 — Recommended Standard 232 is a standard interface approved by the
Electronic Industries Association for connecting serial devices.
RJ45 — Registered Jack 45 is an eight-wire connector commonly used to connect computers onto a LAN.
RJ48 — Registered Jack 48 is an eight-wire connector commonly used to connrct
T1 lines.
SNMP — Simple Network Management Protocol is a set of protocols used for managing complex networks and network devices.
SDRAM — Synchronous Dynamic Random Access Memory is a type of DRAM that can run at much higher clock speeds than conventional memory.
SFTP — Secure File Transfer Protocol is a method of transferring files between computers over a secure SSH secure data stream.
SSH— Secure Shell is a
program to log into another computer over a network, to execute commands in a remote machine, and to move files from one machine to another
STELNET— Aa standard terminal emulation program that allows remote login and connection to systems/servers on a network. Telnet uses a single TCP/IP network connection to provide this remote login, control, and communication functionality
TDM — Time-Division Multiplexing allows transmitting and receiving telephone switches to create channels within a transmission stream. A standard DS0 voice signal has a data bit rate of 64 kbit/s. A TDM circuit runs at a much higher signal bandwidth, permitting the bandwidth to be divided into time frames (time slots) for each voice signal which is multiplexed onto the line by the transmitter.

Telnet — Telnet is a standard terminal emulation program that allows remote login and connection to systems/servers on a network. Telnet uses a single TCP/IP network connection to provide this remote login, control, and communication functionality. STELNET is the secure version of this program.
TCP — Transmission Control Protocol provides a reliable stream delivery and virtual connection service to applications through the use of sequenced acknowledgment with the retransmission of packets when necessary.
UPS — Uninterruptible Power Supply is a power supply that can run off of a backup battery when primary power is lost.
UDP — User Datagram Protocol provides a simple, but unreliable message service for transaction-oriented services. Each UDP header carries both a source port identifier and a destination port identifier, allowing high-level protocols to target specific applications and services among hosts.
VLAN — Virtual Local Area Network refers to a network of computers are connected to a single physical segment of a wire but behave as if they are connected to the physically diverse LANs.
VAC — Volts Alternating Current
VDC — Volts Direct Current
VCCI — Voluntary Control Council for Information Technology Equipment (Japan)
