Cabling the 5802 and 5877 to the server

Learn how to cable the 5802 and 5877 to the server.

1. Install the GX Dual-Port 12X Channel Attach adapter (12X) adapter into your server.
2. Connect the 12X DDR cable to your 5802 or 5877 expansion unit. For information on 12X DDR cables, see RIO/HSL, 12X/12X DDR, and SPCN cable identification.
   Note: Two modes are available for connecting the 12X interface:

   • Double barrel mode: Using two 12X DDR cables, connect port 0 of the 5802 or 5877 expansion unit to port 0 of the 12X interface on the server, and connect port 1 of the 5802 or 5877 expansion unit to port 1 of the 12X interface on the server.
   • Loop mode: For details about the loop mode, see Example: Topologies of RIO/HSL, 12X, and 12X DDR loops.
3. Install the other end of the 12X DDR cable to the 12X adapter on the server.
4. Add the disk drives to the operating system you are using.
