PROGRAM CARD

Use the following procedures to replace your program cards in the event that you

wish to load new ﬁrmware or if you had to remove the program card for some

reason:

Program Card Upgrade—Nonredundant Conﬁguration

An HS operating ﬁrmware upgrade causes a brief interruption in service to

attached drives. The operating system should automatically recover from this

outage within a few seconds after the new ﬁrmware becomes operational and

restores service.

Use the following procedure to upgrade the ﬁrmware (replace the program card)

in a nonredundant controller:

1. Locate the controller to be shut down.

2. Attach an ESD grounding strap to your wrist at one end and to a cabinet

grounding stud at the other end.

3. Remove the ESD shield over the program card by pulling the two plastic

push/pull pins on each side of the shield.

4. Press the program card eject button to eject the old program card from the

controller.

5. Remove the program card.
