The fiber optic cables from the output of the Transceiver can be home runs to the
individual fiber C/Ports, or they can be patch cables that run to one or more fiber patch
panels.
The following requirements apply to the ClearCube Fiber Optic Extension System:
• The power budget through all the connections between the Transceiver and the
Fiber C/Port must be 6 dB or less, including the cable itself.
• This system connects PC blades at a maximum distance of 2000 meters over a pair
of 50µm or 62.5µm multi-mode fibers.
PC Blade Installation
Unpacking the PC Blades
Once the chassis has been installed and connected to power and signal connections,
open the PC blade boxes and remove the PC blades.
Examine each PC blade for damage as a result of shipping. If you find any damage
contact the carrier to file a claim and call the ClearCube Customer Service
Department for replacement.
Installing PC Blades
Never leave a PC blade out in the open. It should either be in the chassis or in its
storage box. Dust, dirt, and other debris can cause problems so keep the boards clean
by keeping them installed or in their storage box.
• 44–pin interposer—This default configuration enables you to install R-series
blades in R4300 chassis
• 30–pin interposer—Available as a downgrade kit, this interposer enables you to
install R3080D and R1350 blades in an R4200 or in an R4300 chassis. If you use
a 30–pin interposer with the R4300 chassis, you cannot use the USB port on the
rear apron of the chassis.
Do not use any PC blade that shows any sign of damage. Subsequent
damage from a defect caused by shipping could be extensive.
Never force blades into a chassis. Mishandling blades can cause
critical hardware failure, data loss, or both.
NOTE
The interposer on the rear of R-series blades determines the
chassis in which you can install them.
