2-port GPDsk components

The 2pGPDsk consists of a motherboard, a memory daughter card, and a
power supply daughter card, with a hard disk mounted on the motherboard.
The 2pGPDsk connects to the shelf backplane, providing an interface to both
fabric cards.

100BaseT Ethernet cable assembly

The minimum grade of cable required for a 100BaseT Ethernet port is
Category 5 unshielded twisted pair (UTP). Some installations may require a
higher grade cable (for example, Enhanced Category 5 UTP cabling) to
overcome cross-talk, immunity, and other noise problems.
Attention: In order to meet Class B electromagnetic compatibility (EMC)
requirements, use shielded twisted pair (STP) cabling.
