User Operation
This chapter describes the hardware features and functions of the L351.
3.1 L351 Functions
Each L351 requires a host for power. The L351 can function as a non-managed, standalone unit; as a
managed, standalone unit; or as a managed unit in a chassis with other application modules.
3.2 Power Up
During the initial power-up sequence, all LEDs light amber. When start-up is complete, the setup and
installation are correct, and data is transmitting normally across the link, the STA LED lights green
and the LNK/Rx and Tx LEDs for both ports light green or blink green when they transmit or receive
data. See Table 3-1.
3.3 Front Panel LEDs
The LEDs on the front panel show the system and port conditions. The STA LED shows the link
condition. The LNK/Rx and Tx LEDs show the conditions on the User and Extension Ports and can
be used as an aid when troubleshooting a fault. Table 3-1 shows the LED states for various
conditions.
In the UCS 1000 and 1001, a BAM holds up to two L351s. On the BAM, the STA LED lights green
if either L351 is operating normally. If both L351s are in error conditions, the BAM STA LED lights
amber.
3.4 Alarms
The L351 can generate Major and Minor Alarms.
• In the UCS 1000 and 1002, these alarms are forwarded over the backplane to the CIM and appear
on the Major (MAJ) and Minor (MIN) CIM LEDs and then are forwarded to the DMM for
monitoring and transfer to the Network Manager as traps.
• In the UCS 1001, the alarm outputs are forwarded to the chassis motherboard.
For details about the Alarm Output Configuration, Alarm Log, and Trap Configuration screens,
reference Chapter 4.
