2. PRODUCT OVERVIEW
The CityLIGHT Fibre Channel Card is part of the CityLIGHT system and is
designed to provide a basic transport service for Fibre Channel attached
devices. It converts multimode 850nm or single-mode 1300nm fiber
signals for transmission on single-mode fiber between connected devices
over distances up to 15km on single-mode fiber using short haul optics or
40km using long haul optics.
Two versions of the Fibre Channel Card are available offering different
interfaces to the user’s equipment.
a) 850nm Multimode
b) 1300nm Single-mode
Figure 1 - CityLIGHT Fibre Channel Card
2.1 Data Rate
The CityLIGHT Fibre Channel Card transmits at a data rate of 1062 Mbps.
2.2 Drive Distance
The CityLIGHT Fibre Channel Card allows a user to connect LAN
interfaces over extended distances. Every CityLIGHT Fibre Channel
Card single-mode fiber link can be up to 15km using short haul
optics or 40km using long haul optics.
CITYLIGHT FIBRE CHANNEL CARD
11
Note the short haul optics are limited in distance by the spectral
width of the laser and not the power budget available on the link.
See Specifications Section for more details of drive distance.
2.3 External Attenuator
All high-power or long haul CityLIGHT cards have been designed for long
distance transmission and provide a minimum optical budget ranging between
20dB and 25dB. This provides transmission distances between 40km and
50km based on an average fiber attenuation of 0.5dB/km.
When these products are used for short distance applications, the received
power may exceed the saturation limit of the receiver and external attenuation
will be necessary to prevent optical overload and the inevitable data errors.
For these applications, an external 10dB attenuator is available to ensure that
the optical receive power falls within the operating limits of the receiver.
The fixed value 10dB attenuator, LCL505A, is of a doped-fiber design which
eliminates the troublesome reflections which an air-gap attenuator may
introduce. These reflections can upset the operation of lasers, particularly
those used in high data rate systems.
The 10dB attenuator may be deployed anywhere in the single-mode fiber link
but it is recommended that it be deployed at the receive end (rather than the
transmit end) of any particular point-to-point link.
The attenuator has a female connector at one end and a male connector at
the other end. The connector style should be specified at the time of ordering.

2.5 Ergonomics
The CityLIGHT Fibre Channel Card is able to be installed in any of the
CityLIGHT chassis types.
2.6 Power Supply
The CityLIGHT Fibre Channel Card receives all its power requirements from
the PSUs mounted in the CityLIGHT chassis. Consult your chassis manual for
details.
2.7 Management
The CityLIGHT Gigabit Ethernet Card is managed via the CityLIGHT SNMP
Card.
Once installed in a chassis with an SNMP card or connected via the fiber to a
card in an SNMP-managed chassis, the SNMP agent automatically detects
the card and displays the following information.
NOTE: This information is the same for the local and remote cards and
is available via the terminal interface as well as the SNMP MIB.
i) Card Type.
ii) Fiber Port Link Status.
iii) Temperature.
iv) Fan Status.
v) Laser Bias Current Alarm.
vi) Receive Power.
vii) PSU Voltage.
viii) Redundant PSU State.
ix) Serial Number.
x) Firmware Version Number.
xi) Location.
Card Type
The type of the card in the slot (Fibre Channel in this case).
CITYLIGHT FIBRE CHANNEL CARD
14
Fiber Port Link Status
This gives an indication of the state of the fiber connections to the CityLIGHT
Fibre Channel Card.
The single-mode fiber port states can be:
i) Inserted (both ends are inserted and can carry data - single-
mode receive port is correctly connected).
ii) Rx Alarm (the CityLIGHT Fibre Channel Card is not receiving
light from the far end device. A fault lies in the far end device
or the receive fiber path).
iii) Check Rx and Tx (there is a fault in the transmit path from
this CityLIGHT to the far end CityLIGHT card).
The user fiber port states can be either:
i) Link UP (the CityLIGHT Fibre Channel Card is receiving a
carrier signal on the single-mode/multimode port).
ii) Link DOWN (the CityLIGHT Fibre Channel Card is not
receiving a carrier signal on the single-mode/multimode port).
iii) ACTIVE (both ends are inserted and carrying data).
Temperature
This is the temperature of the CityLIGHT Fibre Channel Card. A trap alarm is
generated if the temperature is not within the required range.
NOTE: This temperature monitors the actual temperature of the
electronics on the card. Acceptable values are from -10°C to +70°C.
Fan Status
The 1U Chassis has fan-assisted cooling. The SNMP Card monitors the fan
speed in both the local and remote chassis and an alarm is generated if the
fan speed falls below a pre-set limit. Care should be taken not to block the
inlets or outlets of the fans on either side or rear of the chassis.
Laser Bias
This field results from monitoring the drive current required to maintain the
correct output power of the lasers on the Fibre Channel transceiver cards. It is
used to generate a trap when a threshold value is exceeded. This indicates
that the laser is approaching its end of life (though typically the laser will not
during an appropriate maintenance window.
CITYLIGHT FIBRE CHANNEL CARD
15
Rail Voltage
The voltage actually present at the card. In non-redundant PSU chassis this
can be used to monitor the state of the power supply and should always be
greater than 4.9V.
PSU
This field gives an indication of the operating state of the PSUs in the
CityLIGHT chassis associated with the transceiver displayed, i.e. the local or
remote CityLIGHT chassis. The displayed state of the PSUs can be any one
of the following:
i) Good.
ii) Under voltage (the voltage on the card is too low).
iii) Over voltage (the voltage on the card is too high).
Serial Number
This field gives the serial number of the CityLIGHT Fibre Channel Card in the
selected slot of the CityLIGHT management chassis.
Firmware Version Number
The factory loaded firmware version resident on the Fibre Channel Card.
Location
The location is entered by the user; see CityLIGHT SNMP Card installation
manual for details.
Other Managed Features
The CityLIGHT SNMP Card also monitors the PSUs and cooling fans of
chassis. Refer to the installation manual supplied with the CityLIGHT SNMP
Card for more details.

3. INSTALLATION
NOTE: The CityLIGHT Gigabit Ethernet Card is hot-swappable; the power
to the CityLIGHT 1U or 3U Chassis and the CityLIGHT 2-Card
Chassis does not need to be turned off during installation.
3.1 Tools Required
To install the CityLIGHT Fibre Channel Card, the following tools are required:
Flat-Bladed Screwdriver
Rack/Suitable Bench Space
Fiber Cleaning Kit
Fiber Patch Cords
Loss Set (Power Meter and 1300 nm Light Source)
3.2 Before You Start
Make sure you have the following information at hand before you start:
Fiber Configuration: Check that the connections on the CityLIGHT Fibre
Channel Card, the patch cords used, and the site requirements are
compatible.
As the CityLIGHT Fibre Channel Card is a long-distance product, installation is
greatly simplified with a technician at each end of the link. This allows link
tests to be completed in the least amount of time.
3.3 General Set-Up
1) If an SNMP Card is used on the link, set switch 1 on both cards to ‘R’
(Remote). See Section 5, Switch Positions.
If no SNMP card is present one card must be set to OFF ‘L’ (Local);
the other card must be set to ON ‘R’ (Remote). Unspecified results will
occur if not configured in this way.
2) Position the CityLIGHT Fibre Channel Card at the required slot of
either the CityLIGHT SNMP Chassis or the CityLIGHT 2 Card
Chassis.
CITYLIGHT FIBRE CHANNEL CARD
17
3) Push the CityLIGHT Fibre Channel Card along the card guides into
the slot until it engages with the connector inside the CityLIGHT
chassis.
4) Tighten the two captive screws on the front panel of both CityLIGHT
Fibre Channel Cards to secure them in position.
5) Make sure the Rx Alarm LED and Link LED on the front panel of both
CityLIGHT Fibre Channel Cards illuminate.
6) Using the loss set, and ideally a technician at either end of the link,
check that the link budget is less than 18dB for the short haul unit or
20dB for the long haul unit.
7) VERY IMPORTANT: Thoroughly clean the connectors using pure
alcohol and lint-free materials. Allow to air dry or blow with clean
compressed air. Never blow dry using breath. If available fiber
cleaning tape may be used.
8) Connect the fiber cables to the Tx connectors at both ends of the link.
9) Measure the received light level at the far end of the link. Check that
the received light level is between -6dBm and -20dBm. If the received
light level is greater than -6dBm an attenuator is required.
10) Connect the fiber cable to the receiver (Rx connector). Make sure the
Single-mode Alarm LED is extinguished, see Section 4, Diagnostic
LEDs. If the Alarm LED is illuminated, check that the receive power is
greater than -20dBm. If it is less than -20dBm check the launch
power of the far end device and that the fiber connections are correctly
made Tx to Rx.
11) Power up the local user equipment and make sure the Link LED is
green indicating that the link to the connected Fibre Channel port is
now active. If the Link LED remains red, check that the receive power
at the user port is greater than -17dBm. If it is less than -17dBm,
check the launch power of the connected device. Check the fiber
connections are correctly made Tx to Rx.
NOTE: The receive power figures detailed above are for the 850nm
multimode version. For the 1300nm single-mode version, receive
power must be greater than -19dBm.
12) Once the link is correctly inserted, check the following:
i) The Link LED is green.
ii) The Rem F LED is extinguished.
iii) The Alarm LED is extinguished.
CITYLIGHT FIBRE CHANNEL CARD
18
If any of the LEDs is not correctly illuminated/extinguished see
Appendix A - Troubleshooting for possible causes.
NOTE: During commissioning most faults are associated with bad/wrong
cabling, dirty connectors, incorrect patching, loss of power, or
excessive power budget.
The hardware installation is now complete. To enable management, refer to
the Management Serial Interface section of the CityLIGHT Card installation
manual.
