Removing the Routing Engines
The router can have a RoutingEngine in each of the slots labeled RE 0
and RE 1 at the rear of the chassis, as shown in Figure3. Each Routing
Engine weighs approximately1.5 lb (0.7 kg).

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wris t and
connect the strap toone of the ESD points on the chassis. Make sure the router
is attached to a proper earth ground. For more information about ESD, see
“Preventing ElectrostaticDischarge Damage” on page 226.
