2.4 Console IOA placement rules for stand-alone systems
In the following sections we list the various rules.
2.4.1 Model 520/550 CEC
The 520/550 will first look for the console in slot 5. If an appropriate IOA is not there, it will
look in slot 2 (which requires a second IOP).
2.4.2 Model 570 CEC
The 570 will first look for the console in slot 4 (which requires a second IOP). If an appropriate
IOA is not there, it will look in slot 6.
If a GX Adapter (for HSL) is installed, it will block slot 6. Since a Twinax adapter would have
to use the same slot as LAN, it cannot be a backup for the LAN in this particular scenario.
Direct (Async) will have to be the backup.
Note: These rules apply to LAN Console and Twinax Console in a stand-alone system. If
using the Direct Operations Console, the ECS card/slot will be used rather than any of the
other slots.
