Hardware Requirements
Hardware Requirements
At least two 6770 switches or 6780 switches (one for the X fabric and one for the Y
fabric) are required. A cable management assembly is required for each 6780 switch.
The switches must be installed and powered on. For Integrity NonStop NS-series
nodes in a layered topology, you can use either the single-mode fiber (SMF) option or
multimode fiber (MMF) option as described in Table 1-2. For example, if you use the
MMF option, you must have MMF PICs installed in both the p-switches and the 6780
switches.
