Figure 90: Fan Tray Assembly Installed
Step 4
To verify that the tray has plugged into the assembly, check the fan tray and listen to determine if the fans are
running.
Stop. You have completed this procedure.
Cable Routing and Management
The ONS 15454 M6 shelf has interchangeable fiber and cable modules. Because the ONS 15454 M6 shelf is
designed to be compliant with ANSI and ETSI 600x300 standards, all the wiring and cable connections are
available on the front side.
Default Module
The ONS 15454 M6 chassis is shipped with the fiber module installed. If you need to use CAT5 cables instead
of optical fibers, you can replace the fiber module with the cable module.
Fiber Module
The minimum fiber bend radius is 1.5 inches. The fiber guide can be replaced with a cable guide to route the
CAT-5 Ethernet cables. The maximum number of 2 mm diameter patch cords that can be managed is 144, or
alternatively, 72 CAT5 cables. To manage extra length fiber and fan out, a dedicated fiber storage unit and
patch panel unit can be installed inside the rack. The maximum capacity of the fiber channel for one side of
the shelf depends on the fiber size and number of Ethernet cables running through that fiber channel. The
details of the fibers are:
• 24 fiber x 6 line cards = 144 fibers (72 fibers for each exit point) or 12 CAT5 cables x 6 line cards = 72
RJ45 cables (36 CAT5 cables for each exit point)
• 4 fibers and 1 RJ45 cable x 2 TNC or TNCE = 8 fibers (4 fibers for each exit point) + 2 CAT5 cables (1
CAT5 cable for each exit point)
