Choosing a PIC Bay
Observe the following guidelines when selecting a PIC bay:
Use the PIC bays on the switch or router base unit first, before installing PICs
■
into an AT-AR040 NSM.
Fill the PIC bays in an AT-AR040 NSM starting at bay 0.
■
You can install a maximum of two AT-AR020 PRI E1/T1 PICs into an AT-AR040
■
NSM, and maximum of four total in a switch or router.
If two AT-AR020 PICs are installed in an AT-AR040 NSM, PIC one must be
■
installed in the lower row (bay 0 or 1) and the other PIC must be installed in the
upper row (bay 2 or 3).
If an AT-AR020 PIC is installed in an AT-AR040 NSM, and operating in E1 mode,
■
you can not install an AT-AR021(S) or AT-AR021(U) PIC in the same row of the
NSM.
You can install a maximum of four AT-AR027 PICs in an AR745 router fitted with
■
an AT-AR040 NSM.
Avoid installing an AT-AR022 or AT-AR026 PIC in an AT-AR040 NSM.
■
Performance of these interfaces may be reduced and packet loss may occur.
