Line Card LEDs
Line card LEDs are described in the documentation specific to each line card. Refer to the installation
documentation that came with the card for to understand LED appearance and meaning.
Installing Switch Fabric Modules (SFM3s)
A minimum of 8 SFM3s are required in order for the E1200 system to operate properly. Nine SFM3s are
required for full line rate, while ten SFM3s creates full redundancy.The chassis allows up to ten SFM3s;
when all 10 are installed, any two may be removed, and the chassis still operates normally.
SFM3s (catalog # CC-E-SFM3) carry user traffic between line cards or between RPMs and a line card.
SFM3s plug directly into the backplane, which provides high-speed access to the line cards. The switch
fabric receives user data packets and redirects them to the appropriate destinations according to the
routing information.

Installing RPMs, Line Cards, and SFM3s
L: Green: link is up
A: Green: activity on port
Red: a critical condition exists, such as a severe overtemperature condition, a fan tray failure,
an overcurrent condition in a power supply, or an out-of-tolerance voltage.
The RPM LEDs are controlled by software which sets the threshold levels for triggering the
different stages of alarms.
Unlit: no major conditions.
Amber: a serious condition exists, such as an overtemperature condition, a single fan failure,
or a line card failure. The RPM LEDs are controlled by software, which sets the threshold
levels for triggering the different stages of alarms.
Unlit: no minor alarm conditions.
Allows you to test the operability of LEDs to verify that they are able to light.
Press the LT button to temporarily illuminate the LEDs on the RPM.
Green: flash memory card is in the process of a read or write process. Do not remove the
flash card when the In Use LED is lit.
Unlit: not in use.
Green: primary
Unlit: secondary (or standby)
This is a bi-color LED.
Green: operational
Amber: fault detected
Flashing green: booting
Unlit: in secondary mode or power is off
This LED is either lit blue or is unlit. It is used to locate a chassis and is turned on via the
command line interface.
