The PCIe I/O infrastructure uses the PCIe fanouts that are installed in the processor (CPC)  drawer to connect to the PCIe+ I/O drawer. The PCIe adapters include the following features: GLYPH<SM590000> FICON Expresss16S+ (two port card), long wavelength (LX) or short wavelength (SX),  which contains two physical channel IDs (PCHIDs) GLYPH<SM590000> FICON Express16S (two port card), long wavelength (LX) or short wavelength (SX), which  contain two PCHIDs (only for carry-forward MES) GLYPH<SM590000> FICON Express8S (two port card), long wavelength (LX) or short wavelength (SX), which  contain two PCHIDs (only for carry-forward MES) GLYPH<SM590000> Open Systems Adapter (OSA)-Express7S 25GbE Short Reach (SR) - New feature GLYPH<SM590000> Open System Adapter (OSA)-Express6S: – OSA-Express6S 10 Gb Ethernet (single port card, Long Reach (LR) or Short Reach  (SR), one PCHID) – OSA-Express6S Gb Ethernet (two port card, LX or SX, one PCHID) – OSA-Express6S 1000BASE-T Ethernet (two port card, RJ-45, one PCHID) GLYPH<SM590000> Open System Adapter (OSA)-Express5S and 4S features (for carry-forward MES only): – OSA-Express5S and 4S 10 Gb Ethernet (one port card, LR or SR, and one PCHID) – OSA-Express5S and 4S Gb Ethernet (two port card, LX or SX, and one PCHID) – OSA-Express5S 1000BASE-T Ethernet (two port card, RJ-45, and one CHPID) GLYPH<SM590000> Crypto Express6S (new build) and Crypto Express5s (only for carry-forward MES). Each  feature holds one PCIe cryptographic adapter. Each adapter can be configured as: – Secure IBM Common Cryptographic  Architecture (CCA) coprocessor – Secure IBM Enterprise Public Key Cryptography Standards (PKCS) #11 (EP11)  coprocessor – Accelerator Chapter 2.
