Cabling Requirements; Rack-Mounting Guidelines - Cisco Catalyst 9400 Series Hardware Installation Manual

Preparing for Installation

Cabling Requirements

When running power and data cables together in overhead cable trays or subfloor cable trays, be aware of the
following caution:
Caution We strongly recommend that power cabling runs and other potential noise sources be located as far away as
practical from LAN cabling that terminates on Cisco equipment. In situations where this type of long parallel
cable runs exist and cannot be separated by at least 3.3 feet (1 meter), we recommend that you shield these
potential noise sources. To avoid interference, the source should be shielded by housing it in a grounded
metallic conduit.
For IEEE 802.3bt Type 4 installations, we recommend using Category 6a cables, rated at 75°C with conductors
23AWG or larger, in bundle sizes of 192 or less.
If your installation does not use the recommended cable, following are the other options that are compliant
to National Electrical Code (NEC):
• Other Category cables (like Category 5e, or Category 6 cables) rated at 75°C, with conductors 23AWG,
• Limited Power (-LP) cable with 0.6A
• Cables with conductors 23AWG, rated at 60°C, in bundle sizes of 61 or less
• Cables with conductors 24AWG, rated at 75°C, in bundle sizes of 91 or less
• Cables with conductors 24AWG, rated at 60°C, in bundle sizes of 37 or less

Rack-Mounting Guidelines

Rack Specifications
Cisco Catalyst 9400 Series Switches are designed to be installed in standard, 19-inch equipment racks that
meet EIA-310-D specifications. Before rack-mounting the chassis, ensure that the equipment rack complies
with all requirements and guidelines
Mounting Location Guidelines
Cisco Catalyst 9400 Series Switches must be front-mounted.
Note * In the illustration, the red and black cables do not interconnect. The two black
cables are connected to the same negative output of the DC source; the two red
cables are connected to the same positive output of the DC source.
in bundle sizes of 192 or less.
