Chapter 1 Overview
The Edge Access L3x2 Series Combination Line Interface Modules (CLIM) convert and extend
Ethernet media between Local Area Networks (LANs) located up to 120km apart.
1.1 L312 Series CLIMs
The L312 receives and transmits 10Base-T full-duplex Ethernet data from a Unshielded Twisted Pair
cable (UTP) and extends it over a multimode or single mode fiber optic cable.
The CLIM front panel, shown in Figure 1, includes:
• User port: RJ-45 modular connector for a UTP cable
• Extension port: ST or SC connecters
• Status LEDs:
• LNK/RX and TX pairs for the User and Extension ports shows link status and that data is
received and transmitted
• STA shows CLIM status
• Normal/X-over switch: Selects the UTP cable type for the User Port. Set to N for a standard
straight-through cable; set to X for a crossed-over cable

Figure 2. Host Options for the CLIM
L312 Ethernet Media Converters
EdgeAccess Universal Chassis System
To install CLIMs in a UCS 1000 or UCS 1001 chassis, you must use a Model 1230 Bus Access
Module (BAM); however, you can install CLIMs directly in a UCS 1002 or Model 1030 Enclosure.
See Figure 2.
• The UCS 1000 Chassis can hold up to 15 model 1230 BAMs with up to two CLIMs per BAM.
This allows a total of 30 L312 CLIMs per UCS 1000.
• The UCS 1001 Chassis can hold up to two model 1230 BAMs with up to two CLIMs per BAM.
This allows a total of 4 CLIMs per UCS 1001.
• The UCS Model 1002 Chassis directly hosts up to 14 CLIMs, or 13 CLIMs with the optional
Domain Management Module (DMM) installed.
• The Model 1030 Standalone Enclosure holds one CLIM.
All CLIMs are hot swappable; they can be inserted or removed at any time without disrupting the data
transfer of other modules in the chassis.
Note: The Chassis Interconnect Module (CIM) must be present in the UCS 1000 or 1002 chassis in
order for the DMM to recognize the L312 modules.

Chapter 2 Set-up and Installation
This section describes how to set up and install the CLIM.
Before setting up the CLIM, make sure the chassis is installed and its Users 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 the chassis to a VT100 type terminal or PC)
• VT100 type terminal or PC to run the User Interface manager
• The DMM and CIM manuals
2.1 Unpack and Inspect
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).
2.2 Set Up the CLIM
Before inserting the CLIM:
• Check the front panel to verify that the CLIM provides the wavelength that matches its link
partner.
• For installation in a UCS 1001 or a Model 1030, or if you plan to use the Hardware Option
Control (see Section 4.6), set SW1; see Figure 3 and Table 1. For more information about the
SW1 functions, see Chapter 3, Alarm Status and Function.
Note: If the CLIM was installed in a UCS 1000 or 1002 and set in the User Interface to software
control, follow these steps to set it to hardware control when installing it in a UCS 1001 or
Model 1030:
a. Set SW1, all positions, to On.
b. Insert the CLIM in a slot with the power on, then remove it.
c. Set SW1, all positions, to Off.

2.2.1 Install a CLIM in a BAM Host
Each BAM can hold up to two CLIMs. See Figure 4.
Follow these steps to install the BAM and the CLIM:
Step 1. Insert a BAM into an available slot. Slide the BAM into the rails and push it firmly into the
backplane, then tighten the captive screws. If you encounter resistance, pull the BAM out
and check that no connector pins are bent on the BAM or the chassis backplane.
Step 2. Insert a CLIM into an unused slot in the BAM. Slide the CLIM into the rails and push it
firmly into the backplane, then tighten the captive screw. If you encounter resistance, pull it
out and check that no connector pins are bent on the CLIM or the BAM backplane.
If you encounter more difficulty, contact Canoga Perkins at (818) 718-6300 for technical assistance.
Note: CLIMs and BAMs are hot-swappable and can be inserted or removed without disrupting data
transfer in other application modules.

2.2.2 Install a CLIM in a UCS Model 1002 or 1030 Enclosure
Insert a CLIM into an unused slot. Slide the CLIM into the rails and push it firmly into the
backplane, then tighten the captive screw. If you encounter resistance, pull it out and check that no
connector pins are bent on the CLIM or the backplane.
If you encounter more difficulty, contact Canoga Perkins at (818) 718-6300 for technical assistance.
Note: CLIMs are hot-swappable and can be inserted or removed without disrupting data transfer in
other modules in the chassis.
2.3 Install the Cables
The CLIM uses both electrical and fiber optic cables. Electrical UTP cables connect to the User Port.
Fiber optic cables connect to the Extension port.
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.
Follow these steps to clean the cable and connectors:
Step 1. 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. See Figure 5.
L312 Ethernet Media Converters

EdgeAccess Universal Chassis System
Figure 5. Cleaning Fiber Optic Cables and Connectors
Step 2. Use canned air to blow out any dust from the female fiber coupler.
Follow these steps to connect the cables:
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
Step 1. Plug in the optical cables. Connect the cables using Tx to Rx orientation.
Caution: To protect the Ethernet port from an intrabuilding lightning surge, use a properly
grounded shielded cable.
Step 2. Plug the UTP Ethernet cable with RJ-45 connector into the User port on the front of the
CLIM.
Step 3. Label each cable and connector with a signal name and direction.
Step 4. For cable connections to other modules in the chassis, see the appropriate user manual for
details.
2.4 Measuring Fiber Link Attenuation and Transmit Power
Canoga Perkins recommends that you determine link attenuation and transmission power before
starting normal link traffic. The attenuation factor and transmission power identify potential
problems with links near the lower limit of receiver limitations.
For details on link attenuation, see Chapter 5. For details on transmission power, see Chapter 5.

Chapter 3 User Operation
This chapter describes the hardware features and functions of the CLIM.
3.1 CLIM Functions
The CLIMs include all functions for media conversion and extension to a remote site. Each CLIM
requires a host for power. The CLIM can function as a non-managed, standalone unit within a larger
system or as a managed unit in a chassis with other application modules.
A BAM holds two CLIMs and is required in the UCS 1000 and 1001 chassis. On the BAM, the STA
LED lights green if either CLIM is operating normally. If both CLIMs are in error conditions, the
BAM Status (STA) LED lights amber.
In the UCS 1001, the alarm outputs are forwarded to the alarm terminal block at the rear of the
chassis.
In the UCS 1000 and 1002, all the traps, alarm outputs, and alarm inputs are forwarded to the DMM
and the CIM in the chassis for management.
3.2 Power Up
During the power-up sequence, all LEDs light amber. When start-up is complete, the setup and
installation are correct, and data is transmitting normally across the link, the STA LED lights green
and the LNK/Rx and Tx LEDs for both ports light green or blink green when they transmit or receive
data. See Table 3.
3.3 CLIM Front Panel Functions
During normal operation, the LED colors change according to system and port conditions. The STA
LED shows the module condition. The LNK/Rx and Tx LEDs show the conditions on the User and
Extension Ports.
The Normal/X-over switch accommodates Ethernet input from straight-through or cross-over UTP
cables. For a straight-through cable, set the switch to "N" (in). For a cross-over cable, set the switch
to "X" (out).
The STA LED shows the operational status of the CLIM, but not the status of the Ethernet signal.
Table 2 shows the STA LED states for various conditions.

The CLIM front panel has two full-duplex, fixed-rate interface ports:
• The User Port receives and transmits the 10Base-T Ethernet signal on UTP cable.
• The Extension Port receives and transmits the Ethernet signal over multimode or single mode
fiber at various wavelengths:
• Multimode 850nm
• Single mode 1310 - 1550nm
The LNK/Rx and Tx LEDs near the User and Extension port connectors show the status for those
ports. Table 3 shows the LED states for various port conditions.

3.4 Alarms
The CLIMs can generate Major and Minor Alarms. In the UCS 1000 and 1002, these alarms appear
on the Major (MAJ) and Minor (MIN) CIM LEDs and are forwarded over the backplane to the DMM
for monitoring and transfer to the Network Manager as traps. For details about the Alarm Log, see
Chapter 4.
3.4.1 Alarm Reporting in Hardware
Alarms (ALM) can be set in hardware at SW1. If ALM is set to On and the alarms configuration is
set to hardware, all configurable alarms are set to Major. Otherwise, the software settings control the
alarms. For details on setting SW1, see Chapter 2. For details on configuring the alarms in software,
see Chapter 4.
3.4.2 Link Loss Forwarding
When LLF is enabled, a fault on one side of the CLIM propagates to the other side to notify that
device and stops signal transmission (brings down the link). Set the LLF propagation to User to
extension, Extension to User, or both directions. Set this from the User Interface or at SW1. For
details on setting SW1, see Chapter 2.
3.4.3 Link Loss Echo
Caution: To avoid a lockup condition, do not set LLE at both the local and remote ends of the
link.
LLE propagates a link loss to the device connected to the Extension Port. If a link loss is detected on
the Extension Port Rx, the Extension Port Tx is disabled, echoing the fault back to the source. LLE
configures the CLIM to not send data until it receives data. Set this in the User Interface or at SW1.
For details on setting SW1, see Chapter 2.

or similar terminal emulation
4.1 VT100 Terminal Emulation
Connect the VT100 terminal emulation session to the DMM used in the UCS 1000 or 1002 chassis.
You cannot manage a CLIM in a UCS 1001 or Model 1030 Standalone enclosure.
For details on the DMM, see the Model 1500 Domain Management Module Users Manual (for UCS
1000) or Model 1502 Domain Management Module Users Manual (for UCS 1002).
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 before you can use
Telnet; for details, see the manual for the DMM.

Chapter 5 Maintenance and Troubleshooting
5.1 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.
5.1.1 Manage Cable Links
Plan to 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 error.
5.1.2 Check Optical Power Levels
To ensure the proper performance levels, measure the fiber link loss, or link attenuation, for all fiber
links. Each CLIM is shipped with a document that lists the output power for each laser transmitter.
To determine link attenuation, use either the CLIM Tx or a hand-held 1310/1550nm laser source, a
fiber optic test jumper cable with known loss, and an optical power meter.
Note: For accurate results, warm up each unit for at least 30 minutes before checking power levels.
The transmit lasers in CLIMs turn on automatically when the CLIM is powered up.

5.1.3 Measure Transmitter Output Power
To measure the output power, follow these steps:
Step 1. Clean the connectors on the fiber optic test cable before plugging in to the Tx connector on
the CLIM.
Step 2. Warm up each component for at least 30 minutes.
Step 3. Set the optical power meter to the proper wavelength.
Step 4. Wait two or three minutes for the power reading to stabilize, then read the output power.
Step 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 CLIM. Measurement tolerance is +/- 0.5dBm.
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 -20dBm.
Step 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.
Step 7. After calculating the link attenuation, subtract that value from the CLIM Tx output value to
determine the power expected at the remote cable end, which is the input power at the remote
receiver.
5.1.4 Measure Receiver Input Power
If you know the link attenuation, skip this section. Otherwise, follow these steps to use the CLIM to
measure the link attenuation.
Step 1. At the local site, connect the fiber link cable to Tx on the CLIM.
Step 2. At the remote site, set the optical power meter to the proper wavelength and connect it to the
fiber link cable.
Step 3. Record the optical power level and compare it with the sensitivity level listed on the data
sheet for the link fiber type.
Step 4. 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.

5.1.5 Measure Fiber Link Attenuation
Determine and record link attenuation before starting normal link traffic. The attenuation factor
identifies potential problems with links that are on the threshold of receiver limitations.
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 CLIM 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 CLIMs.
Use a power meter calibrated for the laser source, then factor in approximately 1dB for the connector
loss from the patch cables between the CLIM and the local device. (Each fiber connection can
generate 0.5dB of additional loss.)
Note: Consider this measurement when extending the Ethernet link at WWDM wavelengths because
the shorter wavelengths have a greater loss.
To measure attenuation:
Step 1. Attach the transmit fiber to the local and remote ends of the link.
Note: To avoid damage, do not over-tighten or force-fit the optical connectors.
Step 2. With a properly calibrated optical power meter, measure the optical power on the fiber that
will be connected to Rx at one site. Record this reading.
Note: Use either a hand-held power meter or other similar measuring device.
Step 3. Repeat this process at the other site.
5.2 Troubleshooting
This section describes fault conditions and corrective action. The multifunction LEDs and the alarms
display all failures.
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 connections before reinstalling
them.
5.2.1 LED Indications
For details on the LED status during a normal start-up, see Chapter 3.
The front panel LEDs show both normal and fault conditions. Additional information about fault
conditions appears in the System Alarms and System Status & Configuration screens. To aid
troubleshooting, Tables 2 and 3 list the functions of the front panel LEDs.

5.2.2 New Installation
On new installations, make sure that all steps in the installation (see chapter 2) are complete:
Step 1. Check that the STA LED is green.
Step 2. Check that the fiber type (multimode or single mode) matches the CLIM optical mode.
Step 3. Make these checks:
• 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 CLIM 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.
• The Normal/X-over switch for the User Port is in the proper position.
5.2.3 SW1 Settings Ignored
If the CLIM was installed in a UCS 1000 or 1002 and set in the User Interface to software control, it
ignores the switch settings when placed in a UCS 1001 or Model 1030. For details on setting the
CLIM to hardware control before installing, see Chapter 2.
5.2.4 Problems With Fiber Optics
If the Extension Port link is down on the System Alarms screen, inspect and clean the cables and
connections, then replace any damaged fiber. Test any components that fail after cleaning.
