Dell Force10 E1200 - RPM Label and Leds

Installing RPMs, Line Cards, and SFMs | 45
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 should 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 9-1 describes the RPM LED states and the RPM front panel.RPMs control the routing and
switching functions for the entire E1200 system. The E1200 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.

L: Green: link is up

Alarms Major Red: a critical condition exists, such as a severe over temperature 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
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.
