(1) Controller canister
(2) Cam handle
4. Move the cam handle to the left to lock the controller canister in place.
5. Reconnect all the cables you removed.
Do not connect data cables to the new HIC ports at this time.
6. (Optional) If you are upgrading HICs in a duplex configuration, repeat all steps to remove the other
controller canister, remove the HIC, install the new HIC, and replace the second controller canister.
Step 6: Complete host interface card upgrade
Complete the process of upgrading a host interface card by checking the controller LEDs and seven-segment
display and confirming that the controller’s status is Optimal.
Steps
1. Turn on the two power switches at the back of the controller shelf.
◦ Do not turn off the power switches during the power-on process, which typically takes 90 seconds or
less to complete.
◦ The fans in each shelf are very loud when they first start up. The loud noise during start-up is normal.
2. As the controller boots, check the controller LEDs and seven-segment display.
◦ The seven-segment display shows the repeating sequence OS, Sd, blank to indicate that the controller
is performing Start-of-day (SOD) processing. After a controller has successfully booted up, its seven-
segment display should show the tray ID.
