OSFP card cable routing

Use this section to understand the cable routing for the OSFP cards.

Power cable routing​

Blind mate – Female side

From	To
1 Left blind mate	1 Retimer board: OSFP card 1 power connector
2 Right blind mate	2 Retimer board: OSFP card 2 power connector

Blind mate – Male side

Note

Route the cables through the cable holders as illustrated below.

	1b GPU baseboard: OSFP card 1 power connector
2 Right blind mate	2a OSFP card 2 (right): Power connector
	2b GPU baseboard: OSFP card 2 power connector

Sideband cable routing​

Note

• If necessary, attach the labels to both ends of the cables.
  1. Attach the white space portion of the label to one end of the cable.
  2. Wrap the label around the cable and attach it to the white space portion.
  3. Repeat to attach the other label to the opposite end of the cable.

4 OSFP card 2 (right): Sideband connector 3/1	4 GPU baseboard: Sideband connector 1	UBB SB 3/1 SB 1

UltraPass cable routing​

Note

• If necessary, attach the label to the end of the cable that connects to the GPU baseboard.
  1. Attach the white space portion of the label to one end of the cable.
  2. Wrap the label around the cable and attach it to the white space portion.
