Hi,<br><br>[For review during our WIMS WG teleconference today]<br><br><br>During the PWG Formal Vote on the Power Model/MIB specs, four <br>vendors made editorial comments:<br><br>--------------------------------------------<br>
Vendor A:<br>[comments on Power Model spec]<br><br>"Line 640 & 641: It seems that the "Suspend power state", on line 640 <br>(being set after 7pm during week days), should be switched with the <br>"Hibernate power state", on line 641 (being set every Friday after 7pm)? <br>
<br>Suspend power state consume less power than Hibernate power state, <br>more appropriate for over the weekend right?<br><br>This seems an editorial oversight, your Power Policy example on Line <br>1529 sets power state to "Suspend" every Friday at 7pm."<br>
<br>[Proposed resolution, discussed offline with Vendor A]<br><br>Resolved confusion about Suspend versus Hibernate power usage<br>
(i.e., Hibernate uses less because OS is NOT still running in RAM).<br>
<br>On line 640, I should change Suspend to Hibernate (best practice).<br><br>On line 641, no change.<br clear="all"><br>On line 1529, I should change Suspend to Hibernate (best practice).<br><br>---------------------------------------------<br>
Vendor B:<br>[comments on Power Model and Power MIB]<br><br>[Power Log Group]<br><br>All Imaging Systems MUST implement this Power Log group as<br>persistent across power cycles and hardware reconfigurations.<br>(section 5.3 in wd-wimspowermib10-20110107.pdf)<br>
<br>-->Do you have any idea about Printer/MFP which doesn’t have a <br>storage like HDD or enough non-volatile memory?<br><br>If you say just as above (MUST implement the persistent across <br>power cycles), I suppose most of low end printers have no chance <br>
to support the power MIB. So it would be helpful for implementer <br>how many logs you need to keep at least (like 10 logs) as a guide line.<br><br>[Proposed resolution, discussed offline with Vendor B]<br><br>REGRESSION LOSS - when the 'MaxXxxRecords' elements were<br>
deleted from Power General group, we lost the specific requirement<br>for a minimum of 10 log entries - this requirement (but not element)<br>should be restored to the Power Model and Power MIB. <br><br>I can note that empty (or canned) PowerStateMessage elements don't<br>
need to be saved in an NVRAM log implementation.<br><br>-----------------------------------------------<br>Vendor C:<br>[comments on Power Model]<br><br>"Should the generalGroup MIB objects powGeneralNaturalLanguage <br>
and powGeneralPolicyMaxAccess be covered in the model document?"<br><br>[Proposed resolution, discussed offline with Vendor C]<br><br>Power Model should clarify why NaturalLanguage is not needed (because<br>it's already in the parent System or Subunit object in SM XML Schema).<br>
<br>Power Model should clarify why PolicyMaxAccess is not needed (because<br>it's coarse access-control, specific to the SNMP binding).<br><br>---------------------------------------------------<br>Vendor D:<br>[comments on Power MIB]<br>
<br>"The Power MIB spec lacks the following two sections that are present in <br>the Imaging System State and Counter MIB:<br><br>"4.2 Indexing of Imaging System State and Counter MIB"<br>- an indexing discussion of sets of groups/tables<br>
<br>"4.3 Diagram of Imaging System State and Counter MIB"<br>- a pictorial representation of the same indexing info<br><br>To improve understanding of the Power MIB by designers, implementers, <br>and testers, we request that these two missing sections be drafted and <br>
reviewed by the WIMS WG for inclusion before the approved Power MIB <br>is published."<br><br>[Proposed resolution, discussed offline with Vendor D]<br><br>Three other vendors independently made a similar comment recently.<br>
<br>I will draft text for these two missing sections.<br><br>----------------------------------------------<br>Comments?<br><br>Cheers,<br>- Ira<br><br><br>Ira McDonald (Musician / Software Architect)<br>Chair - Linux Foundation Open Printing WG<br>
