DC Power Cables
You must supply the DC power cables which meet the specifications in Table 49 on
page 263, or as required by the local code, laws, and standards.
Table 49: Power Cable Specifications

WARNING: For field-wiring connections, use copper conductors only.
WARNING: DC Power cables must not block access to packet transport
switch components or drape where people could trip on them.
CAUTION: Before packet transport switch installation begins, a licensed
electrician must attach a cable lug to the power cables that you supply. A
cable with an incorrectly attached lug can damage the packet transport
switch.
