Processor Switch
The processor switch, or p-switch, provides the first level of ServerNet fabric
interconnect for the Integrity NonStop NS-series processors. ServerNet connection
from the LSU also defines the ID numbers, 0 through 15, for the logical processors
within the system. In cases where NonStop S-series I/O enclosures provide I/O
capabilities and storage for the Integrity NonStop NS-series system, the ServerNet
connection to the p-switch determines the NonStop S-series I/O enclosure group
number, as described in NonStop S-Series I/O Enclosure Group Numbers on
page 2-36.
Two p-switches are required, one each for the X and Y ServerNet fabrics. Physical
attributes for the 3U-high p-switch are:
Rack mountable
Dual AC power feeds and power supplies
Dual fans with front to rear cooling
Main logic board
Maintenance entity (ME) logic and firmware
Maintenance PIC (slot 1) for connection to maintenance switch
Cluster PIC (slot 2) for connection to 6770 or 6780 cluster switch
Crosslink PIC (slot 3) for connection to the other p-switch
