NTRB35 CLKC in card inventory 1

[ArchibaldJCox]

In LD 117 upon printing out the card iventory for an Option 81C CP PII, I have two cards listed as NTRB35AA with what appears to be a card type of CLKC (Clock?) I'm just wondering what it actually is and where it resides. My best assumption is that it is a system clock and there is one one each call processor. Let me know, right or wrong! Thanks!

Hello

NTRB35 clock boards are replacing the old QPC 775.
These boards are seated in CPUs shelfs for Opt 61C or in any network shelf in Opt81C

Excellent, here are the details on Clock Controllers in case anyone else needs this information:

One Clock Controller per CPU is required.
In an Option 51C with an NT5D21 Core/Net, the Clock Controller is located in Slot 9

In an Option 61C with two NT5D21 Core/Nets, there is one Clock Controller in each Core/Net located in Slot 9

In an Option 61C with two NT4N41 Core/Nets, there is one Clock Controller in each Core/Net located in Slot 9

In an Option 81C, regardless of core/net, one Clock Controller per shelf is required and they are located in Slot 13 of two of the network modules (One in any network module of Group X, Shelf 0 and one in any network module of Group X, Shelf 1)

Hooray, one problem knocked down today!

Thanks for the help, dlesap!
