Chapter 1 Unpacking and Installing the CSS
Installing a CSS 11800 Module
Installing a Passive SCM or SFM
You can install a passive SCM or SFMs (which includes SFM2s) in a CSS 11800
chassis. Passive modules are stand-by modules in case of an active module
failure. When an active module fails, the passive module becomes active. Passive
modules do not load share processing functions with the active module.
Note The SCM contains a small lithium battery. Some jurisdictions
restrict the ways in which items containing lithium batteries may be
disposed. In particular, lithium batteries or products containing
lithium batteries may never be disposed of in an unregulated fire.
Other restrictions might apply. Refer to Appendix A, Specifications
for lithium battery safety warnings.
Warning Ultimate disposal of this product should be handled according to
all national laws and regulations.
The CSS 11800 enables you to install a passive:
• SCM for the active SCM
• SFM for each of the two active SFMs (total of four SFMs)
Note You can mix SFMs with SFM2s in the same CSS 11800 chassis.
However, you must use the same type module as the active SFM and
as the passive SFM.
To install a passive SCM or SFM:
1. Properly ground yourself prior to handling the module.
2. As defined in Table 1-1:
• SCMs are restricted to slots 7 or 8
• Passive SFMs are restricted to slots 5 and 10 (with active SFMs in slots
6 and 9, respectively)
3. If necessary, remove a blank panel from the chassis to expose a slot.
