Normal Mode

Upon power–up or reset, the CSMIM2 enters normal mode. The
following subsections describe both the possible error, and error-free,
conditions that can occur during power-up and booting in normal mode.
4.2.1.1

Normal Mode Error-free Sequence

Table 4-1 summarizes the indicator display sequences during error-free
power-up in normal mode.
Table 4-1 Normal Mode Error-free Indicator States
Activity
N1: Indicators OK
N2: Hardware OK
Key: = On continuously
= Flashing regularly (about 1Hz)
4.2.1.2

Activity N1: Testing Indicators

All front panel indicators light for a few seconds, then all but the
Ethernet channel indicator (segment indicator) turn off, confirming that
all indicators are operational.
4.2.1.3

Activity N2: Testing the Hardware

During the power-up sequence, the CSMIM2 runs a series of self-test
diagnostics. These diagnostics test internal hardware functions. If a test
fails, the Attn and Stat LEDs flash and an error message is displayed if
the console port is selected. The Ethernet Channel indicator lights for a
few seconds, then the Traf indicator flashes during the power-up
self–tests. After the self–tests complete, only the Stat and Ethernet
Channel indicators remain on.
