Goal

Description of the PUM Motherboard LED light sequence.

Solution

Steps to Follow
Refer to the attached document for information on the LED sequence.
These LEDs are link status indicators for the internal hub built into the PUM motherboard.

There are 16 LEDs located along the top of the PUM card. They are situated in pairs (P0, P1, and so forth, as listed in Table 1) and indicate the state of internal Ethernet connections within the library.

- The left LED = Yellow (Data is being transferred)
- The right LED = Green (Link state is good).
During installation of the cables, you should see the green LEDs illuminate for the related cable.

This information will be added to the SL3000 Service Manual in the near future.
