StorageTek L180 and L700 DC Power Problems
We buy a fair number of used L180 and L700 tape libraries, and we have
noticed a fairly large number of these systems have one of the two DC power supplies dead. Opening these always shows a burn at exactly the same transistor on the PCB. Recently we had a unit under test where the DC power started to fail as well. Have other users of these libraries experienced a high failure rate on this component? Is there some know revision of this part that avoids this problem? -- Will westes AT earthbroadcast.com |

"CHANGE USERNAME TO westes" wrote in message ... On both the StorageTek L180 and L700 tape libraries, I have noticed that if the library is run in an environment with a high ambient temperature (over about 80-to-85 degrees), you start to get problems with tapes getting stuck Sounds like you need to check the environment you are purchasing used units from. We have 8 L700s and 2 L180s, and the only failures we have experienced in 3 years are DLT drive failures, but those are pretty much expected over time. Admittedly we run them in much more resonable ambient temeratures (~70-74F). If your ambient room temperature is 80-85 degrees, then the internal temps may be exceeding the 90 degrees the library is spec'ed t (according to the on-line data sheet). |
