Installing the M40e Fan Tray

To install the fan tray (see Figure 84 on page 170):
CAUTION: When sliding the fan tray into the chassis, take care not to catch
and pinch any dangling PIC cables with the edges of the tray. Also make sure
your fingers are not near the fans, which start spinning as soon as the fan tray
contacts the midplane.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
1.
the strap to one of the ESD points on the chassis. For more information about ESD,
see "Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series
Router" on page 232.
Grasp the sides of the fan tray and align the rear of the tray with the guides inside the
2.
chassis.
Slide the fan tray all the way into the chassis.
3.
Tighten the thumbscrew at each end of the cable management system.
4.
Rearrange the PIC cables in the cable management system. For more information
5.
about proper cable arrangement, see "Maintaining M40e PICs and PIC Cables" on
page 139.
