Installing a Second RPM
Install a second RPM either before the system is powered on or after the Primary RPM is up and stable.
After the second RPM is installed, wait several seconds until the connection between the two RPMs is
established before configuring any commands. Below is an example of the messages that appear:
%POLLMGR-2-ALT_RPM_STATE: Alternate RPM is present
%IRC-6-IRC_COMMUP: Link to peer RPM is up
%RAM-6-RAM_TASK: RPM1 is in Standby State.
Once the link between the two RPMs is established, copy the running configuration to the startup
configuration.
RPM Label and LEDs
Table 7-1
describes the RPM LED states and the RPM front panel.
RPMs control the routing and switching functions for the entire E600i system. The E600i operates with a
minimum of one RPM module. You can hot-insert a second RPM into a running system without
performance interruption or software intervention. A second RPM for redundant functionality provides
uninterrupted operability if the system transitions from the primary RPM to the secondary (standby)
RPM. The secondary RPM constantly performs updates and receives the same information received by
the primary RPM. The secondary RPM also performs diagnostics on its subsystems. In the event of a
switchover, the secondary RPM immediately takes over and resumes the control activities that the
primary RPM was performing.

Alarms Major Red: a critical condition exists, such as a severe over temperature condition, a fan tray
failure, an over temperature 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.
Minor Amber: a serious condition exists, such as an over temperature 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.
ACO/LT Allows you to test the operability of LEDs to verify that they are able to light.
Press the ACO/LT button to temporarily illuminate the LEDs on the RPM.
If you press this button when the alarm status LED is lit, the alarm relay contacts are reset
until the next alarm event.
