I/O Module

A ztC Endurance system contains two I/O modules: I/O module A and I/O module B. Figure 2 shows the location of each I/O module in a system.

Figure 7 shows an individual I/O module. Each I/O module provides:

• Ethernet ports. See System Ports.

  • One 1G (RJ45) port for an out-of-band management network

  • Two 10G (RJ45) ports

• Status LEDs, which indicate the status of the I/O module. See Status LEDs.

• Five PCIe 4.0 slots for half-height PCIe adapters. For additional information about PCIe adapters, see:

  • System Specifications for information on the supported PCIe adapters.

  • Communications Line Planning for information on the communications lines.

  • PCIe Adapters for information about PCIe-adapter configuration and numbering.

  • Removing and Installing a PCIe Adapter for maintenance information.
