When using 4-port network cards in one of the low-profile slots, the server chassis obscures one of the ports by about 0.5 to 1 mm. Inserting a GBIC (or SFP transceiver) is possible with some force, but subsequent removal is very difficult or impossible.

• Potential Fixes
  • When purchasing network cards with 4 slots, use the OCP3.0 port if possible.
  • For stuck GBICs, gently wiggle while pulling or use a flathead screwdriver for leverage without forcing, to prevent port damage.
