Chapter 1
Overview
The Edge Access L3x2 Series Combination Line Interface Modules (CLIM) convert and extend fast
Ethernet media between Local Area Networks (LANs) located up to 120Km apart.
1.1 L322 Series CLIMs
The L322 receives and transmits 100Base-T full-duplex Ethernet data from a UTP or fiber optic
cable. The CLIM converts the data to or from an electrical signal and extends it over a variety of
multimode or single mode fiber optic links.
The CLIM front panel, shown in Figure 1, includes:
•User port: RJ-45 modular connector for a UTP cable.
•Extension port: SC connecter, simplex or duplex; simplex requires a pair of L322s, one at
1310 nm wavelength and the other at 1550 nm wavelength
•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

EdgeAccess®Universal Chassis System
L322 Fast Ethernet Media Converters 1-3
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. 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 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 1002 Chassis directly hosts up to 14 CLIMs, or 13 CLIMs with the optional 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 chassis in order for the DMM
to recognize the L322 modules.

Set-up and Installation
This section describes how to set up and install the CLIMs.
Before setting up the CLIM, make sure installed chassis (see the manual for the UCS chassis) is
available. 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 manual for the chassis and optionally, the DMM, and the CIM
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 100 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.
d. Insert the CLIM in a slot with the power on, then remove it.
e. Set SW1 positions as needed.

2.2.1Install 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 [phone] for technical assistance.
Note: BAMs are hot-swappable and can be inserted or removed without disrupting data transfer in
other application modules.

2.2.2Install 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 [phone] 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. UTP cables connect to the User Port while
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.

L322 Fast Ethernet Media Converters
2-4
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.
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.
•If you have a simplex optical connector, use a bi-directional cable between a pair of L322s, 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 to avoid transmission
errors.
Caution: To protect the Ethernet port from an intrabuilding lightning surge, use a properly
grounded shielded cable.
Step 2. Plug the unshielded twisted pair (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 the signal name and direction.
Step 4. For cable connections to other modules in the chassis, see the appropriate user manual for
details.
2.3.1Measuring Fiber Link Attenuation and Transmit Power
It is recommended to 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
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 the 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 Figure 1.
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 indicates the operational status of the CLIM. It does not indicate the status of the
Ethernet signal. Table 2 shows the STA LED states for various conditions.

Red CLIM Self Test Failure
The CLIMs include two full-duplex, fixed-rate interface ports that convert and extend 100Mbps
Ethernet data through the User and Extension Ports. 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.
•The User Port receives and transmits 100Base-T Ethernet signal on UTP twisted pair cable.
•The Extension Port receives and transmits the Ethernet signal over multimode or single mode
fiber at various wavelengths:
•Multimode 850 - 1310nm
•Single mode 1310 - 1550nm

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 SW 1. For
details on setting SW 1, 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.
3.4.4 Remote Fault
If the Extension port Rx loses the signal, it sends a Remote Fault (RMTF) signal from its Tx, the Rx
LED is off, and an alarm flags the link loss on the Extension port.
When the Extension port receives a Remote Fault signal, the Rx LED lights red and an alarm flags the
remote side optical link failure. Both local and remote link partners must be configured to the same
RMTF enable/disable setting.

Management - VT-100
If the system includes a DMM and a CIM, you can manage the system through VT100 Terminal
Emulation, which is accessible by a Telnet session, HyperTerminalTM or similar terminal emulation
software, a standard SNMP network manager, and CanogaView.
4.1 VT100 Terminal Emulation
Connect the VT100 terminal emulation sessions through 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.
4.2 PC Configuration for Terminal Operation
These steps briefly describe how to set up your PC for a terminal connection. For details on using
Windows, see your Windows documentation.
Step 1. Turn on your PC.
Step 2. When the main Windows screen (desktop) appears, click Start, highlight Programs,
Accessories, the HyperTerminal Folder, and click HyperTerminal.
Step 3. At the Connection Description dialog, select an icon and enter a name for the connection to
the system and click OK. See Figure 6.
