Installation Cooling Requirements
If you install the maximum of eight GX-1420B or GX-1421A SmartCards (into 16 card
slots) in an SMB-2000 chassis, be sure to cover the remaining four card slots with blank
panels to maintain proper air flow throughout the chassis. (This is not an issue with the
SMB-200.)
When using less than eight SmartCards in a chassis, you can populate the remaining card
slots with other card types. For every one GX-1420B or GX-1421A card less than the
recommended maximum (eight), you can substitute either:
• One GX-1405B or AT-9xxx SmartCard, or
• Two SX-/ML-xxxx, WN-xxxx, or TR-8405 SmartCards.
Warning: Failure to follow these rules may result in blown fuses within the SMB-2000
chassis. To replace a blown fuse, refer to Chapter 4, “Maintenance and Upgrade
Procedures.”
