4 Replacing the Boot ROMs in the Cisco 2500 Series and AccessPro PC Card Routers

Removing the Cover or AccessPro PC Card

Figure 2 Chassis Cover Removal—Part A (Top) and B (Bottom)

Step 4

Remove the single screw on the bottom of the chassis at the side closest to you. (See

Figure 2, Part A.) Note that the chassis consists of two sections: top and bottom. (See

Figure 2, Part B.)

Step 5 If required, insert a medium ﬂat-blade screwdriver into the slots shown in Figure 2, Part A,

and gently rotate the blade so that the top and bottom sections separate slightly.

Step 6 Holding the chassis with both hands, position it as shown in Figure 2, Part B.

Step 7 Pull the top section away from the bottom section. (See Figure 2, Part B.) The ﬁt is very

snug, so it may be necessary to pry the chassis sections apart at one end and then the other

until they separate.

Step 8 When the top cover is off, set it aside.

Warning To prevent shock hazard and injury, do not touch the power supply or fan assemblies.

Step 9 Proceed to the section “Replacing the Boot ROMs—All Models” on page 7.
