Procedure
Whenever installing or removing units from the HMS-358 chassis, be sure to wear an
antistatic wrist strap and connect it to the ESD strap input.
1
Unscrew the two hold-down lugs on each upper corner of the chassis front cover. The cover folds
down.
2
Hold the HMU-319 vertically with the front of the card toward you. Align the top and bottom edges
of the HMU-319 with the guide rails in the HMU slot and slide the HMU-319 into the rightmost slot
position on the chassis (labeled HMU). See
3
Press the HMU-319 firmly into the connector at the back of the slot.
When the pins on the HMU-319 connect to the pins on the shelf backplane, the HMU-319 powers up,
the Power LED glows green, and the Fail LED and Critical LED briefly flash red.
