Fig. 7.2 shows the location of the GW-Link ports on the front of each IPU-M2000.

Table 7.2 gives the IPU-M2000 GW-Link port mappings between the two IPU‑POD64 racks, with the GW-Links cross connected:

  • GW-Link port 1 of each IPU-M2000 in the left-hand IPU‑POD64 connects to GW-Link port 2 of the matching IPU-M2000 (same rack index) in the right-hand IPU‑POD64.

  • GW-Link port 2 of each IPU-M2000 in the left-hand IPU‑POD64 connects to GW-Link port 1 of the matching IPU-M2000 (same rack index) in the right-hand IPU‑POD64.
