Caution You must place the edge of the air filter flush against the front of the fan-tray assembly compartment
when installing the fan tray on top of the filter. Failure to do so could result in damage to the filter,
the fan tray, or both.
Caution Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray
and/or the connectors on the back panel of the shelf assembly.
Step 1 Open the front door of the shelf assembly. Removing the front door is optional.
Step 2 Slide the fan tray into the shelf assembly until the electrical plug at the rear of the tray plugs into the
corresponding receptacle on the backplane.
Step 3 To verify that the tray has plugged into the backplane, check that the LCD on the front of the fan tray is
activated.
Figure 1-21 shows the location of the fan tray.
