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.

Be sure to plug your ESD wrist strap into the ESD above the HMU slot.

Lift the retention bar at the top of the chassis to allow insertion of the module.

Slide the line unit into the card guides for the desired slot, then push the unit in until it touches the
backplane card-edge connector and the retaining latch on the front panel opens
5
Place your thumbs on the line unit front panel and push the line unit into the card-edge connector until
it is entirely within the card guides and the retaining latch closes. This indicates that the card is properly
seated.
Do not enable alarms at this point in the procedure. You will not fully configure the HLU until the line
