EdgeAccess Universal Chassis System
Chapter 1
Overview
The 2346 Managed T3 Fiber Optic Modem converts and extends T3/DS3 signals between devices located up to 100 Km apart. Use the modem to extend a PBX, router, video codec, M13 multiplexer, or ATM switch. The 2346 receives and transmits 44.736 Mbps data on single mode or multimode fiber optic cable.
The 2346 front panel, shown in Figure 1, includes:
• Electrical and optical connectors
• Reset switch
• LEDs for:
• System status
• Configuration
• Electrical signal
• Optical signal
Figure 1. The 2346 Front Panel
The 2346 can be used in a variety of chassis. To install a 2346 in a UCS 1000 or UCS 1001 chassis, you must use a Model 1230 Bus Access Module (BAM); however, you can install a 2346 directly in a UCS 1002 or standalone enclosure.
• The UCS 1000 Chassis can hold up to 15 model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of 30 2346 modems per UCS 1000.
• The UCS 1001 Chassis can hold up to two model 1230 BAMs with up to two 2346 modems per
BAM. This allows a total of four 2346 modems per UCS 1001.
• The UCS 1002 Chassis directly hosts up to fourteen 2346 modems, or thirteen 2346 modems with
the optional Domain Management Module (DMM) installed.
• Each standalone enclosure, such as a Model 1020 or 1030E, holds one 2346 modem. The 2346 is hot swappable; you can insert or remove it at any time without disrupting the data
transfer of other modules in the chassis.

Hardware Installation and Functions
Before setting up the 2346, make sure the chassis or enclosure is installed and its User Manual is available for reference. If the system includes an optional DMM and CIM(s), make sure these are available:
• Serial cable (required to connect to a VT100 type terminal or PC)
• VT100 type terminal or PC to run the User Interface Manager software
• The DMM and CIM manuals

Set Up and Installation

Unpack and inspect all components. Save the shipping carton and packing materials in case you need to return the equipment to the manufacturer. Appendix A provides information for Return Material Authorization (RMA).
1. Before inserting the 2346, check the front panel to verify that the 2346 provides the wavelength that matches its link partner; see Figure 1.
2. Set SW2-1 and 2-2; see Figure 2.
• SW2-1, Line Buildout (LBO): Off (default) for Short LBO, <225 ft (68 m), or On for Long
LBO, >225 ft; when software control is enabled at the Functional Configuration screen, SW2-1 is ignored.
• SW2-2, Software override: Off (default) is software, On is hardware; set to Hardware in
unmanaged environment, only. For installation in a managed environment where you plan to use software control (see page 3-11), set SW 2-2 to Off.
Note: If the 2346 was previously installed in a managed environment and set in the User Interface
to software control, follow these steps to set it to hardware control when installing it in an unmanaged environment:
a. Set SW2-2 to On. b. Insert the 2346 in a slot with the power on, then remove it. c. Set SW2-2 to Off. d. Insert the 2346 in a slot with the power on, then remove it. e. Set SW2-2 as needed.
3. Set jumper W10 as needed for normal (to NP) or wide pulse (to WP); see Figure 2. NP is the default.

4. To install a 2346 in a UCS 1000 or 1001 chassis, you must use a Model 1230 BAM; each BAM can hold up to two 2346 modems. Follow these steps to install the BAM and the 2346:
a. Insert a BAM into an available slot in a UCS 1000 or 1001. Slide the BAM into the rails and
push it firmly into the backplane, then tighten the captive screws. If you encounter resistance, check that no connector pins are bent.
b. Insert a 2346 into an unused slot in the BAM. Slide the 2346 into the rails and push it firmly
into the backplane, then tighten the captive screw. If you encounter resistance, check that no connector pins are bent.
5. To install a 2346 directly in a UCS 1002 or standalone enclosure, insert the 2346 into an unused slot. Slide the 2346 into the rails and push it firmly into the backplane, then tighten the captive screw. If you encounter resistance, check that no connector pins are bent.
If you encounter more difficulty, contact Canoga Perkins at (818) 718-6300 for technical assistance.
Note: The BAM and 2346 are hot-swappable and can be inserted or removed without disrupting
data transfer in other application modules.
6. If the 2346 is in a standalone enclosure, set the switch on the enclosure for loopback to Normal.
The 2346 uses electrical cables to connect to the local site and fiber optic cables to connect to the remote modem. Follow these steps to connect the electrical and optical cables:
7. To connect to the local site, plug the BNC cables from the local equipment into the Rx and Tx connectors using Tx to Rx, and Rx to Tx orientation.
Dirty optical connectors are a common source of link loss or attenuation problems, especially for single mode fiber (SMF). Clean the connectors before plugging in a cable and whenever there is a significant or unexplained light loss. To prevent contamination, always install protective dust covers on unused fiber optic connectors.
8. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free isopropyl alcohol pad from a fiber cleaning kit.
9. Use canned air to blow out any dust from the female fiber coupler.
2-2
2346 T3 Modem
EdgeAccess Universal Chassis System
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
10. Plug in the optical cables:
• If you have a simplex optical connector, use a single strand, single mode fiber cable between
a pair of 2346 modems, one at 1310 nm wavelength and the other at 1550 nm wavelength.
• If you have a duplex connector, use Tx to Rx, and Rx to Tx orientation.
11. Label each cable and connector with a signal name and direction.
12. For cable connections to other modules in the chassis, see the appropriate user manual for details.
13. Measure and record fiber link attenuation and transmission power before starting normal link
traffic in order to identify potential problems with links near the lower limit of receiver limitations. For details on link attenuation and transmission power, see Chapter 4.

Power Up and Front Panel Functions

During the initial power-up sequence, all LEDs light amber. When start-up is complete and data is transmitting normally across the link, the STA LED lights green and the CFG/TST, LOS, and CLS LEDs are off. During normal operation, the LED colors change according to system and port conditions. The STA and CFG/TST LEDs show the module condition. The LOS and CLS LEDs show the electrical and optical signal conditions. Table 3 shows the LED states for various conditions.
Table 1. 2346 LED Functions
LED Status Description

EdgeAccess® Universal Chassis System

Alarm Functions

The 2346 can generate Major and Minor Alarms.
• UCS 1000 and 1001: a BAM is required and holds up to two 2346 modems. On the BAM, the
Status (STA) LED lights green if either 2346 is operating normally. If both modems have errors, the BAM STA LED lights amber.
• UCS 1001: the alarm outputs are forwarded to the chassis motherboard.
• UCS 1000 and 1002: the alarms are forwarded over the backplane to the CIM and appear on the
Major (MAJ) and Minor (MIN) CIM LEDs and then are forwarded to the DMM for monitoring and transfer to the Network Manager as traps.
• Model 1020 enclosure: the alarm information is forwarded to the management session.
• Model 1030 enclosure: alarms are not supported.
For details about setting up the Alarms, see Chapter 3; for viewing the Alarm Log, see Chapter 4.

Software Management
You can manage the 2346 through VT100 Terminal Emulation, which is accessible by a Telnet session, HyperTerminal or similar terminal emulation software, a standard SNMP network manager, and CanogaView. If the 2346 is in UCS 1000 or 1002 with a CIM within a domain that includes a DMM, you can access the 2346 through the DMM. If the 2346 is a standalone or in a UCS 1001, you must access the 2346 directly through the serial port for the enclosure or BAM.

Setting Up for Network Management

Typically, the 2346 runs within the network on an Ethernet connection, communicating with your Network Management Platform.

Set Up the Network Management Platform

You must run several Management Information Bases (MIBs) on your Network Management Platform in order to successfully manage this module. Before you start, check that Standard MIB (the industry-standard mib) is loaded. In addition, download Cp.mib, a private mib that supports all Canoga Perkins products, available from the Canoga Perkins web site. Go to www.Canoga.com, click Support, then click Software Download, and follow the prompts on screen.

Set Up the PC for Terminal Operation

Connect the VT100 terminal emulation session to the DMM or directly to a 2346, either standalone or in a UCS chassis. Setting up the VT100 session depends on which connection, serial port or Ethernet, you have available for access to the VT100 management program. Canoga Perkins suggests that you use HyperTerminal for your first session.
You must set up TCP/IP for the DMM or directly-managed 2346 before you can use Telnet; for details, see the manual for the DMM or go to page 3-7.
Note: For details on the DMM, see the Model 1500 Domain Management Module User Manual (for
UCS 1000) or the Model 1502 Domain Management Module User Manual (for UCS 1002).
These steps briefly describe how to set up your PC for a terminal connection. For details on using Windows, see your Windows documentation.
1. Turn on your PC.
2. Accessories, the HyperTerminal Folder, and click HyperTerminal.
3. At the Connection Description dialog, select an icon, enter a name for the connection to the
system, and click OK.

Update Software

Each module in the Universal Chassis System has two flash memory banks that store software:
• The Active Flash Memory holds the software currently in use
• The Inactive Flash Memory holds the new software from a download or the older version of
software
Software is downloaded to the inactive region to avoid disrupting service. Resetting the module and swapping banks does not affect module operation and is transparent to user traffic.
Use the Software Upgrade report and menu screen to check the current version of the 2346 firmware and to upgrade software for any module in the domain or a managed module partner, if necessary.
To access the Software Upgrade screen, follow these steps:
1. At the Main Menu, type
5, "Software Upgrade," and press <Enter>.
2. At the Software Upgrade screen, record the numbers for the Active and Inactive Firmware.
3. Access the Canoga Perkins Web site, click Downloads, scroll to the 2346 filename, and compare
the version number listed there with the version numbers you recorded. The 2346 firmware file name is similar to
23460106.zip, where "2346" indicates the module and "0106" indicates the
version.
Caution: To insure compatibility when a system includes two or more of the same module, you
must upgrade all those modules with the same software.
If the firmware for the 2346 is outdated, Canoga Perkins recommends that you upgrade it.
4. You can download the software through the DMM (for details, see the manual for your DMM) or,
if the 2346 is in a UCS 1001 or a standalone enclosure, follow these steps to start the software upgrade:

Manage Security

To provide system security, the 2346 includes username and password access, as well as SNMP with Read and write communities and a Host table. To set up values for various security parameters on your 2346, you must typically have supervisor access.

Set Up Host Access

The SNMP agent allows access to up to 24 Host IP addresses listed in the Host Access Table. Set up the Host information for access to the 2346 on the Host Access Table screen. When a host attempts to access the 2346, the IP address is authenticated against the entries on the host table. If a user attempts SNMP access from a host or network that is not listed in this table, the 2346 rejects that host and generates an authentication trap. To access the Host Table, follow these steps:
1. At the SNMP Configuration Parameters menu, type The Host Table screen appears.
2. To add a host, type parameters:
a. IP Address: for the Host b. Access Level: Read, Read/Write Read/Trap, or Read/Write/Trap c. Trap Community: the community name for requests from the host or network

Monitor Modem Performance

You can monitor the performance of both the local and remote modems at the Link Errors report. The report includes timers and checks for signal errors. In addition, the 2346 uses the Bit Error Rate Test (BERT), which sends a continuous 127-bit sequence within the optical data stream to check for bit errors while the optical signal remains in sync. The link Errors screen monitors these conditions:
• Timer: Number of days, hours, minutes, and seconds since the last reset
• Composite LOS Errors (CLS): Number of optical loss of signal errors
• Electrical LOS Errors: Number of electrical loss of signal errors
• Errored Seconds (BPVs): Number of seconds with at least one BiPolar Violation (BPV)
• SQL Rx Errors: Number of received squelch occurrences
• BERT Sync Status: Reports loss if CLS occurs or OK if signal is good
• BERT Sync Count: Number of good to faulty patterns
• BERT Bit Errors: Number of bits with errors in the received pattern
• BERT BER (1E-9): Number of bit errors during this BERT up time
• BERT Up Time: How long BERT is available and running

Maintenance and Troubleshooting
Well-maintained modules and cabling can help ensure trouble-free operation.

General Maintenance

Well-maintained components and clearly identified cables help assure optimum system operation. Damaged fiber cables and dirty connectors are a common source of signal loss or attenuation. Single mode and multimode fiber optics are especially sensitive to contamination. Inspect, clean, and test all components to maintain optimum performance.
Note: To avoid damage and signal loss, do not over-tighten or force-fit optical connectors.
• To clean the ferrules and end-face surfaces of male fiber couplings, use a lint-free pad saturated
with isopropyl alcohol.
• To clean the female fiber connectors, use canned air.
• To prevent damage and contamination, place protective dust caps on all unused optical
connectors.

Manage Cable Links

Manage the cables to ensure trouble-free operation and maintenance tasks.
• Position and secure the fiber optic cables to prevent excessive bends and damage. Follow the
guidelines for the bend radius for specific fiber cables.
Note: If no minimum bend radius is specified, the typical long-term, low-stress radius is not less
than 15 times the cable diameter (based on Federal Standard FS-1037C).
• Always connect the fiber optic cables in the standard Tx to Rx and Rx to Tx scheme; reversing
this can cause transmission conflicts.
• Label each fiber cable near each end with the signal direction, source, and destination to
minimize connection errors.

Check Optical Power Levels

To ensure the proper performance levels, measure the fiber link loss, or link attenuation, for all fiber links. Each 2346 is shipped with a document that lists the output power for each laser transmitter. To determine link attenuation, use either the 2346 Tx source or a hand-held 1310/1550 nm laser source, a fiber optic test jumper cable (with known loss), and an optical power meter.
Measure optical fiber links at the shortest wavelength of operation to determine the limiting factor in the loss budget. Each device that transmits to a 2346 has a loss budget that is specified by the manufacturer and recorded on a data sheet provided with the equipment. That loss budget must be greater than the total of the measured loss of the fiber link and the attenuation of the 2346.
4-1
EdgeAccess® Universal Chassis System
Note: For accurate results, warm up each unit for at least 30 minutes before checking power levels.
The transmission laser in a 2346 turns on automatically when the chassis receives power.
To measure the output power, follow these steps:
1. Clean the connectors on the fiber optic test cable before plugging it in to the Tx connector on the 2346.
2. Warm up each component for at least 30 minutes.
3. Set the optical power meter to the proper wavelength.
4. Wait two or three minutes for the power reading to stabilize, and then read the output power.
5. Subtract out the test cable loss, then record the power level and compare it to the value on the performance sheet for that particular 2346. Measurement tolerance is +/- 0.5 dBm.
Note: When referencing optical power levels with numerical values less than zero, the reading
closer to zero is the greater value; for example, -17 dBm is greater than -20 dBm.
6. If the reading is incorrect, repeat the measurement with a different test cable. If the power level is still not within range, call Technical Support.
If you know the link attenuation, subtract that value from the 2346 Tx output value to determine the power expected at the remote cable end, which is the input power at the remote receiver, and skip this section. Otherwise, continue these steps to use the 2346 to measure the link attenuation.
7. At the local site, connect the fiber link cable to Tx on the 2346.
8. At the remote site, set the optical power meter to the proper wavelength and connect it to the fiber link cable.
9. Record the optical power level and compare it with the sensitivity level listed on the data sheet for the link fiber type.
10. Subtract the remote power level from the value for the transmitter output power at the local site. The result provides the link loss, in dB. This power level must not exceed the limit for Rx sensitivity listed on the data sheet for the remote unit.
Note: If you cannot determine the Rx sensitivity, contact Canoga Perkins Technical Support
Department for assistance.
11. Repeat this process at the other site.

Troubleshooting

This section describes fault conditions and corrective action. As a rule, whenever there is a significant signal loss, check the fiber path and the minimum bend radius for potential problems. Remove and inspect the cable connectors, being careful not to damage the fiber end-face surface or the connector housing. Clean all optical connectors before reinstalling them.

The front panel LEDs show both normal and fault conditions. Typically, if a LED is steady red, the fault is in the local 2346; if it blinks red, the fault is in the remote modem. Additional information about fault conditions appears in the System Alarms and System Configuration screens. To aid troubleshooting, Table 1 lists the functions of the front panel LEDs. For details on the LED status during normal start-up and operation, see Chapter 2.
Additional information about fault conditions appears in the System Alarms, Hardware Configuration, and Functional Configuration screens.

Check a New Installation

On new installations, make sure that all steps in Chapter 2 are complete, then make these checks:
• The STA LED is green
• The fiber type (multimode or single mode) matches the 2346 optical mode
• All fiber cabling is of the same type; do not mix multimode and single mode cables
• The fiber optic cable is within the specifications and loss budget of the optic interface module
• The line length between the 2346 and the remote link does not exceed the allowable loss
budget or overdrive limit
• All host modules in the link are turned on
• All fiber cables are connected Tx to Rx and Rx to Tx

Loopback

Use loopback to diagnose a fault on the optical link, either on a modem or with a cable. The 2346 supports both local and remote loopback in one or both directions. Set loopback either in software for a managed 2346 or at the loopback function switch on a standalone enclosure See Figures 4 through 9.
• Local loopback returns the received electrical signal to the local site and ignores the received
optical signal; turn on Local Loopback at the local modem. The remote modem returns All Ones to the remote site. Faulty data can indicate that the local 2346 is faulty.
• Remote loopback returns the received optical signal to the remote modem and ignores the
received electrical signal; turn on Remote Loopback at the local modem. The remote modem returns All Ones to the remote site. Faulty data can indicate that either the fiber optic cable link or the remote 2346 is faulty.
• Bi-directional loopback returns the received electrical signal to its local site and the received
optical signal to the modem that sent it; turn on Local loopback at one modem and Remote Loopback at the other modem. Faulty data can isolate the faulty equipment to indicate that either the fiber optic link or a 2346 is faulty.
To set up the software and start or stop loopback, follow these steps:
1. From the Main Menu, type
2. At the System Configuration menu, type
Functional Configuration screen appears.
3. Enable Software Override, if needed. Type
between Enabled and Disabled, and press <Enter> to select Enabled. To move to the next column fo r a remote modem, press <Tab>.
