Reinstalling 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 Figure 3.
NOTE: If two Routing Engines are installed, they must both be the same version.
To reinstalla Routing Engine, follow this procedure (seeFigure 51):
1. 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.
