Setup And Configuration - 512 Port Solution - Brocade Communications Systems 1606 Manual

DATA CENTER
The following items are required to implement this LC cable management solution for a 256 port LC patch
panel solution utilizing the Brocade DCX with four FC8-64 port blades:
•
Four XBR-000306 1RU 72 port LC-LC patch panels
•
256 mSFP-LC cables of 2-meter length
• Roll of Velcro & scissors
•
Four Cord Management Sleeves

ETUP AND ONFIGURATION
This section describes how to cable up a 512 port DCX using an MPO/MTP solution with the FC8-64 port
blades. Unlike the LC direct port-to-port cable mapping, for the 512 port DCX solution, ruggedized fan-out
cables are used.
These have a MPO connector on one end and six duplex mSFP connectors on the opposite end. Thus, each
fan-out cable supports six mSFP ports. Once the cable labeling scheme has been defined, as described in
the "Establishing a Naming Scheme" section in this document, label the ports on the patch panel using the
table listed in the Appendix. It is important to map the DCX slot and port number to the MPO fan-out cable
and port number and patch panel/shelf/MPO port number.
Two 1 rack unit patch panel shelves, each with three MPO pass-thru panels, are required. Each 1RU MPO
patch panel supports 72 MPO ports, totaling 432 LC ports for connectivity. There will be 48 unused MPO
patch panel ports with this configuration.
In the following example, 2-meter cables are used to connect the director ports to the ports on the patch
panel with staggered cable lengths for mSFP ports (Figure 3) to minimize the cable slack at the port.
NOTE: If both 1-meter and 2-meter cables are available, use the 2-meter cables for ports 16-31 and ports
48-63. This will minimize the extra fiber that must be managed inside the rack.
Patch Panel Installation:
1. Install the patch panels below the cable comb with a 1 rack unit gap between the cable comb and the patch
panel.
2. Test each shelf by sliding out each self for service accessibility (Figure 9).
