Cable reference

Edit online

The cable standard tables specify cable types and standards for customer-supplied cables for use with the system.

Table 1 provides a list of Ethernet cable standards. Ethernet cables are not supplied with the system. Ensure that the cables that are used meet the minimum standards for the Ethernet port type.
