Fans The S5000 supports two fan trays with airflow directions from I/O to Utility or Utility to I/O. Do not mix I/O to Utility and Utility to I/O airflows in a single S5000 chassis. All fans and PSUs in a configuration must be in the same airflow direction. If you create a mixed airflow configuration, the software notifies you of the invalid configuration. The fans must be installed at the customer site. Port Numbering Convention Even-numbered ports are at the bottom of the I/O panel and for modules odd-numbered ports are at the top of the I/O panel. Figure 4. Port Numbering The previous figure shows the fixed four 40GbE data ports (ports 48, 52, 56, and 60) and the four slots for pluggable modules on the S5000 I/ O panel. You can also use the 40GbE ports in 4 × 10GbE mode. The S5000 supports the following possible modules: • 12-Port Ethernet Module (1G/10G speeds) (slot 0, 1, 2, or 3) • 12-Port Fibre Channel Module (2G/4G/8G speeds) (slot 0) The valid slot numbers are stack-unit numbers (from 0 to 11). The valid port numbers for each interface type are: • 1GbE: Ports 0 to 47 • 10GbE: Ports 0 to 63 • 40GbE: Ports 48, 52, 56, and 60 • Fibre Channel: Ports 0 to 11 8
