10 Upgrading Memory in Cisco 4000 Series Routers

Removing the Component Tray

Step 6 To remove the component tray, pull on the handle at the upper right corner of the rear

panel.

If your chassis has a safety latch (see Figure 2), slide the component tray out of the

chassis shell just until the safety latch catches. Support the component tray with one hand,

push down on the safety latch tab, and pull the component tray out the rest of the way.

If your chassis does not have a safety latch (see Figure 3), support the component tray

with one hand while you slide it out of the chassis shell.

Step 7 Set the tray on your work surface.

Figure 4, Figure 5, Figure 6, and Figure 7 show component trays for routers in the Cisco 4000 series.

(Figure 4 shows the original Flash EPROM daughter card for the Cisco 4000; if your daughter card

has been replaced, its appearance will differ.)
