Advantech MIC-5332, User Manual

Page: 58 / 129

If the BMC watchdog is enabled again for OS load supervision, the user needs to
make sure the running OS will reset or disable the BMC watchdog afterwards. If not,
the IPMC will reset the payload as the timeout action.
The default timeout period for the BMC watchdog used as the BIOS POST timer and
OS load supervision is 60 seconds. This setting can be changed through the BIOS
setup menu. Please refer to
Section 5.6.3, Watchdog Timer Configuration
.
Note
:
‹
To assure a safe booting process, the BMC watchdog timer cannot be set to
less than 60 seconds
.
4.5 E-Keying
Electronic Keying (E-Keying) is a mandatory mechanism of PICMG® 3.0 system
management infrastructure, which is used to dynamically satisfy the needs that had
traditionally been satisfied by various mechanical connector keying solutions:
‹
Prevent damage to boards
‹
Prevent mis-operation
‹
Verify fabric compatibility
4.5.1 Zone3 (RTM)
The IPMC on the MIC-5332 and the MMC on the RTM handle the E-keying control.
For the RTM, the PCI Express ports need E-keying to carry out the hot swap function.
Brief E-keying information of the zone 3 is listed in Table 4.10. The user may also get
a detailed E-keying connectivity record via a CLI command through the shelf
manager.
