Chapter 5 Maintaining the Cisco 10008 Router
Upgrading SDRAM on the PRE
Caution Always tighten the captive screw on the PCMCIA flash card cover to prevent the risk of a harmful ESD
event and to ensure electromagnetic interference (EMI) shielding.
Figure 5-49 Tightening the Captive Screw
Step 5
Close the cover and tighten the captive screw (Figure 5-49).
Step 6 Replace the front cover if necessary (see the “Replacing the Front Cover” section on page 5-6).
Upgrading SDRAM on the PRE
You can increase the amount of SDRAM in your system configuration by replacing the two dual in-line
memory modules (DIMMs) with higher capacity SDRAM. The default SDRAM configuration is
128 MB, and can be upgraded to either 256 MB or 512 MB to meet your needs (Table 5-1).
Note We recommend that you upgrade the SDRAM in both the primary and the secondary PRE in a redundant
chassis configuration. The DIMMs that you remove may be used in other compatible equipment and
should be stored in an antistatic bag.
