Figure 61: Reinstalling an SFM
Reinstalling the Rear Component Cover
The rear component cover protects the Routing Engines, PCGs, MCSs, and SFMs, as
shown in “M40e Chassis Description” on page 8. To reinstall the rear component cover:
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
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.
2.
Hold the component cover up to the rear of the chassis and align the flanges at the
top and bottom with the top and bottom of the opening in the chassis.
3.
Push the cover into place.
4.
Tighten the thumbscrew at each corner of the cover.
CAUTION:
To maintain proper airflow and provide electromagnetic
shielding, do not operate the router without the rear component cover in
place.
Reinstalling the Power Supplies
The two power supplies (AC or DC) are located at the bottom rear of the chassis, as
shown in “M40e Chassis Description” on page 8. To reinstall the power supplies (see
Figure 62 on page 107, which shows a DC power supply):
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
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.
2.
Verify that the power switch for each power supply is in the
OFF
(
O
) position. On an
AC-powered router, the switch for each power supply is on the power supply faceplate.
On a DC-powered router, the switches are on the circuit breaker box.
