Installing and Maintaining the E1200i System 31
Access the fan tray slots from the rear of the chassis (Figure 9). Two fan trays are required in the chassis.
When a fan tray is not installed in the lower slot, a self-closing door will seal the slot. Panel blanks are not
required. However, to ensure fail-safe chassis operation, do not operate the chassis with only one fan tray
for more than 30 minutes.
Chapter 6 Installing Fan Trays
Warning: Install the fan trays before you supply power to the system.
Warning: Electrostatic discharge (ESD) damage can occur when components are mishandled.
Always wear an ESD-preventative wrist or foot-heal ground strap when handling chassis
components. After you remove the original packaging, place chassis components on an antistatic
surface.
