Managing Cable Connections to MDA-a and MDA-
aXP Cards
All cable connections to MDA-a cards are made from the front of the 7750 SR-a chassis. The
MDA-a cards can be connected using Ethernet, copper, or fiber-optic cables. The 7750 SR-a
chassis are designed to enable cable routing and management from the front of the chassis.
Ethernet and Copper Wire Cables
For a horizontally mounted chassis, Ethernet and copper wire cables can be routed to the left
or right of the chassis using the (optional) wire-form cable management brackets, described
in
Installing the Wire-Form Cable Guides on page 89 .
To maintain EMC compliance, cables that are shielded and grounded at both ends must be
used with the adapter card interfaces. Use CAT5e shielded cables with Gigabit Ethernet
interfaces (electrical).
To attach Ethernet and copper wire cables:
Step 1. Attach the cable to the port connector or SFP connector on the adapter card.
Step 2. Route the cables to the left or right of the chassis.
Step 3. Attach the cable to a distribution panel or appropriate connector.
Warning: To prevent damage to the components during installation, such as damage to the
faceplate connectors, avoid excessive bending, twisting, and pulling of Ethernet and copper
wire cables. When bundling the cables, leave enough slack to allow room to move the
cables aside during servicing and to prevent stress at the termination to the module.
