Chapter 1
Overview
The Edge Access L351 Series 10/100BASE Media Converters convert and extend Ethernet media
between Local Area Networks (LANs) located up to 120 Km apart.
In addition, the L351 offers Layer 2 statistics, local and remote loopback, remote software upgrade,
and remote control and monitoring through the SideBand Management Channel (SBMC).
1.1 L351 Series
The L351 receives and transmits 10/100BASE Ethernet data on single mode or multimode fiber optic
cable.
The L351 front panel, shown in Figure 1-1, includes:
• User port: UTP connector
• Extension port: SC connector, simplex or duplex; simplex requires a pair of L351s, one at
1310 nm wavelength and the other at 1550 nm wavelength
• Status LEDs:
• STA shows L351 status
• CFG shows configuration and setup status
• 100 and FDX show status for the User port
• LNK/RX and TX pairs for the User and Extension ports show that data is received and
transmitted

1.2 L351 Hosts
The L351 can be used in a variety of chassis. To install the L351 in a UCS 1000 or UCS 1001
chassis, you must use a Model 1230 Bus Access Module (BAM). However, you can install the L351
directly in a UCS 1002 or Model 1020 or 1030 enclosures.
• The UCS 1000 Chassis can hold up to 15 Model 1230 BAMs with up to two L351s per BAM.
This allows a total of 30 L351s per UCS 1000.
• The UCS 1001 Chassis can hold up to two Model 1230 BAMs with up to two L351s per BAM.
This allows a total of four L351s per UCS 1001.
• The UCS 1002 Chassis directly hosts up to 14 L351s, or 13 L351s with the optional Domain
Management Module (DMM) installed.
• A 1020 or 1030 standalone enclosure holds one L351.
The L351 is hot swappable; it can be inserted or removed at any time without disrupting the data
transfer of other modules in the chassis.

2.2.1 Install the L351 in a BAM Host
Each BAM can hold up to two L351s. Follow these steps to install the BAM and the L351:
1. Insert a BAM into any available slot of either a 1000 or 1001 chassis. 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.
2. Insert the L351 into an unused slot in the BAM. Slide the L351 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.
If you encounter more difficulty, contact Canoga Perkins at (800) 360-6642 for technical assistance.
Note: The L351 and BAM are hot-swappable and can be inserted or removed without disrupting
data transfer in other application modules.

2.2.2 Install the L351 in a UCS Model 1002 or Standalone Enclosure
Insert the L351 into an unused slot. Slide the L351 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. If you encounter more difficulty, contact Canoga Perkins at (800) 360-6642 for
technical assistance.
Note: The L351 is hot-swappable and can be inserted or removed without disrupting data transfer
in other modules in the chassis.
2.3 Install the Cables
The L351 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 install the cables:
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.
2. Use canned air to blow out any dust from the female fiber coupler.
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
3. Plug in the optical cables:
• If you have a single fiber connector (BIDI), plug the cable into a pair of L351s, one at 1310
nm/1470 nm wavelength and the other at 1550 nm wavelength.
• If you have a duplex connector, use Tx to Rx, and Rx to Tx orientation.
Caution: To protect the Ethernet port from an intrabuilding lightning surge, use a properly
grounded shielded cable.
4. Plug the UTP Ethernet cable with RJ-45 connector into the User port on the front of the L351.
5. Label each cable and connector with a signal name and direction.
2.4 Measure Fiber Link Attenuation and Transmit Power
Canoga Perkins recommends that you determine and record 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 and transmission power, see Chapter 5.

User Operation
This chapter describes the hardware features and functions of the L351.
3.1 L351 Functions
Each L351 requires a host for power. The L351 can function as a non-managed, standalone unit; as a
managed, standalone unit; or as a managed unit in a chassis with other application modules.
3.2 Power Up
During the initial 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 3-1.
3.3 Front Panel LEDs
The LEDs on the front panel show the system and port conditions. The STA LED shows the link
condition. The LNK/Rx and Tx LEDs show the conditions on the User and Extension Ports and can
be used as an aid when troubleshooting a fault. Table 3-1 shows the LED states for various
conditions.
In the UCS 1000 and 1001, a BAM holds up to two L351s. On the BAM, the STA LED lights green
if either L351 is operating normally. If both L351s are in error conditions, the BAM STA LED lights
amber.
3.4 Alarms
The L351 can generate Major and Minor Alarms.
• In the UCS 1000 and 1002, these 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.
• In the UCS 1001, the alarm outputs are forwarded to the chassis motherboard.
For details about the Alarm Output Configuration, Alarm Log, and Trap Configuration screens, see
Chapter 4.

3.4.1 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.
RMTF complies with the IEEE802.3u Remote Fault standard.
Figure 3-1. Remote Fault Signal
3.4.2 Link Loss Forwarding
When Link Loss Forwarding (LLF) is enabled, a fault on one side of the L351 propagates to the other
side to notify that device and stops signal transmission (brings down the link). See Figure 3-2. Set the
LLF propagation to User to Extension, Extension to User, or both directions. Set this in the User
Interface or at SW3-2 (L) and SW3-3 (U). For details on setting SW3, see Chapter 2.
Figure 3-2. Link Loss Forwarding Propagation
L351 10/100BASE Media Converter 3-3
EdgeAccess Universal Chassis System
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.
Link Loss Echo (LLE) propagates a link loss to the device connected to the L351 Extension Port. See
Figure 3-3. 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 L351 to not send data until it receives data.
Set this in the User Interface or at SW3-4 (E). For details on setting SW3, see Chapter 2.
Figure 3-3. Link Loss Echo Detection
Note: LLE is available only when SBMC is disabled; use LLF when you enable SBMC.
3.4.4 Loopback
The L351 supports four loopback modes that you can set at the local site for both the Local and
Remote L351s. These modes loop the data through either the physical layer (PHY) on the User side
or the FPGA. For details on setting loopback in software, see Chapter 4.
• Local-Local mode loops the electrical data that the Local L351 receives on the local User Port Rx
through the FPGA to the User Port Tx. The data is not sent out the Extension Port Tx and
incoming data on the Extension Port Rx is ignored. See Figure 3-4. To set this mode at the
Diagnostics screen, set the Loopback State for the Local module to Local.
Figure 3-4. Local-Local Loopback Mode
3-4
EdgeAccess Universal Chassis System
• Local-Remote mode loops the optical data that the Remote L351 receives on the Extension Port
Rx through the User PHY to the Extension Port Tx. The data is not sent out the remote User Port
Tx and incoming data on the remote User Port Rx is ignored. See Figure 3-5. To set this mode at
the Diagnostics screen, set the Loopback State for the Local module to Remote.
Figure 3-5. Local-Remote Loopback Mode
• Remote-Local mode loops the electrical data that the Remote L351 receives on the User Port Rx
through the FPGA to the User Port Tx. The data is not sent out the remote Extension Port Tx and
incoming data on the remote Extension Port Rx is ignored. See Figure 3-4. To set this mode, at
the Diagnostics screen, set the Loopback State for the Remote module to Local.
Figure 3-6. Remote-Local Loopback Mode
• Remote-Remote mode loops the optical data that the Local L351 receives on the Extension Port
Rx through the Local User PHY to the Extension Port Tx. The data is not sent out the local User
Port Tx and incoming data on the local User Port Rx is ignored. See Figure 3-5. To set this mode,
at the Diagnostics screen, set the Loopback State for the Remote module to Remote.
Figure 3-7. Remote-Remote Loopback Mode
For loopback, the L351 uses a unique MAC address that is listed on the Diagnostics screen as Loop
Test MAC Address; for details about using the software and accessing the Diagnostics screen, see
Chapter 4. In loopback mode, the L351 filters the incoming packets to identify the test packets
through the MAC address. You can set two diagnostics options if you want to alter the data during
loopback, Swap MAC Address at Loopback Point, which swaps the test MAC address with the
source MAC address, and Recalculate CRC at Loopback Point. The test packets are returned to the
source according to the selected mode.
