User Operation
This chapter describes the hardware features and functions of the L357.
3.1 L357 Functions and Power Up
Each L357 requires a host for power. 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.
3.2 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 shows the LED states for various conditions.
In the UCS 1000 and 1001, a BAM holds up to two L357s. On the BAM, the STA LED lights green
if either L357 is operating normally. If both L357s are in error conditions, the BAM STA LED lights
amber.
