The 1000BASE-T, 1000BASE-SX, and CSA cards are high-speed cards; most
other option cards are low-speed (33-bit/33-MHz) cards. To maximize system
performance, reserve slots 1, 2, and 6 for high-speed cards, and install low-speed
cards in slots 3, 4, and 5. (The SSL VPN Module 1000 must be installed in slot 1.)
