Ses Controller Card - Fujitsu IRF-1S series User Manual

SES Controller Card

WARNING: The SES Controller card is NOT HOT SWAPPABLE. You must POWER
DOWN the enclosure prior to removing or inserting this card.
The SES Controller card provides the built-in environmental and system status
monitoring. It also houses the switches for setting the drive spin up options. This
card is installed at the rear of the enclosure in the lowest slot below the two Disk
I/O cards.
The SES processors continuously monitor the enclosure for temperature status,
fan status, power supply status, and FC loop status. The processors are
responsible for reporting environmental and system status to the front bezel
LEDs/audible alarms, SES Monitoring software (VT-100), and external monitoring
software such as StorView.
RS-232 Service Port
SES Switches
At power up, the SES processors will read the switch settings and execute a
self-test. The cards' firmware also contains software functions for enclosure
monitoring and management. This firmware is flash upgradeable using the SES
RS-232 Service port located on the card face plate. Refer to "Uploading SES
Controller Card Firmware" on page 119 for more details.
The SES protocol uses the drives installed in slots 1 and 7 to maintain its
communication link. You must install drives in both of these slots to ensure fault
tolerance for the SES communications link.
