Condition: Used
This Telco Systems 3100-40 ISS 2 Network Unit powers on and the indicators light up. We were not able to test it beyond that, so its full functionality is unknown. The unit includes two 6690-00 ISS 3 Power Supply boards and one 2041-00 T1-CSU board. Cosmetically the chassis shows normal wear consistent with rack service use. The front-panel LED indicators on the T1-CSU board and the green power LEDs on both PSU modules were observed lit during power-on. Please view our photo set and contact us if you have any questions.
