Card Descriptions
The external timing interfaces allow operation of the system clock to be
independent of the type of external equipment and the framing of the external
line.
Two connections are possible: one from a primary source and one from a
secondary source. Either connection can provide timing for the entire chassis
(input), regardless of the configuration of the controller cards. See Figure 35
for the location of the connectors for these cables.
An adapter, available as an option, provides wire wrap pins to allow you to
attach a cable without a connector. Support for the other ports depends on
the release of the operating system.
6.1.2.6 Internal Storage for SmartEdge OS files
A controller card has one or two CF cards (Type I), which store SmartEdge OS
images and files. SmartEdge OS storage is organized into three partitions:
p0, p1, and /flash. The p0 and p1 partitions each store a system image and
its files; the memory on a controller card can be loaded from either partition.
The third partition, /flash, stores SmartEdge OS configuration files and other
system- and user-created data files. The capacity of the CF cards can vary;
the CF cards installed in the active and standby controller cards need not have
the same capacity.
6.1.2.7 Optional CF Card
Caution!
Risk of data loss. Use only the CF cards provided by Ericsson. You can corrupt
the system if you attempt to install a CF card not obtained from Ericsson
because these items have not been tested with the SmartEdge router.
A controller card has an external slot on the front panel in which you can install
an optional Type I or Type II CF card. The XCRP4 Controller card supports
Type I CF cards only. When installed (the system is shipped with the slot
empty), the CF card captures crash dumps and provides an alternate source
for loading SmartEdge OS software, if it is not possible to download it over
the network. If a CF card is installed in the active controller card, the standby
controller card, if installed, must also have a CF card installed.
6.1.2.8 Ports for System Management Access
The XCRP4 Controller card has a single Craft port, labeled CRAFT. The CRAFT
2 port is the only enabled Each port has a DB-9 connector and provides an
RS-232 connection to a local console terminal, a terminal server, or a modem.
The Craft port provides access to the SmartEdge OS CLI for configuring and
monitoring tasks; it is enabled on both the active and standby controller cards.
