Removing the Routing Eng ine s
The router can have a Routing Engine in each of the slots labeled RE 0
and RE 1 at the rear of the chassis, as shown in Figure 3. Each Routing
Engine weighs approximately 1.5 lb (0.7 kg).
To remove a Routing Engine, follow this procedure (see Figure 36):
1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. A tt ach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. Make sure t he router
is attached to a proper earth ground. For more information about ESD, see
“Preventing Electrostatic Discharge Damage” on page 226.

of the chassis, and place it on the antistatic mat or in the electrostatic bag.
