Cable management

CAUTION: Gigabit Ethernet ports (intrabuilding ports) of the HP BladeSystem c7000 Carrier-Grade
system require the use of shielded Cat5e cables grounded at both ends. The intrabuilding ports of
the equipment are suitable for connection only to intrabuilding, unexposed wiring, or cabling. Do
not connect the intrabuilding ports of the equipment metallically to interfaces that connect to the
outside plant or its wiring. These intrabuilding ports are designed for use as intrabuilding interfaces
only and require isolation from the exposed outside plant cabling. The addition of primary protectors
is not sufficient protection to connect these interfaces metallically to outside plant wiring.
IMPORTANT:
permanently remove the front rack door for proper cable routing. For more information, see the
documentation that ships with the rack.
To maintain the minimum bend radius, incorporate a system using guides and spools into the rear
sides of the rack. Bundle excess cables around pairs of rack spools. A fiber cable must turn around
a spool or guide.
The rack has a routing area designated for signal cables in the rear left and right sides of the rack.
The area around the bending Z bar is reserved for power cables. Keep signal cables free of the
power cable routing area.
Cable spools are mounted in the cable routing area to bundle excess signal cabling. The
recommended spool locations are 1U above and below the cable management system mounting
brackets. For a standard enclosure installation, the U-locations are U1 and U2.
