J5 Jumper
(AT-PB15 only)
The AT-PB15 module features a J5 jumper. There are two possible
jumper settings: Enable and Disabled. If the chassis does not contain an
AT-PBM02 management module, set the J5 jumper to the Enable
(RIGHT) position. If the chassis contains an AT-PBM02 management
module, set the J5 jumper to the Disabled (LEFT) position. Disabled is the
factory default setting. Refer to Figure 23 for the location of the J5
jumper.
