Insertion or Removal of the PEMs
WARNING:
!
If both PEMs are being supplied with power from the front of the chassis,
make sure that power to the PEM is OFF, and the PEM circuit breaker is
open, before attempting to remove the PEM.
If both PEMs are supplied power from independent power sources from the front of
the chassis, then either PEM can be removed without affecting service.
If both PEMs are supplied with power from the rear of the chassis, then either PEM
can be removed without affecting service by first turning off its circuit breaker
before removal, then turning its circuit breaker back on after insertion.
Populating the GranDSLAM Chassis
HANDLING PRECAUTIONS FOR
STATIC-SENSITIVE DEVICES
This product is designed to protect sensitive components from damage
due to electrostatic discharge (ESD) during normal operation. When
performing installation procedures, however, take proper static control
precautions to prevent damage to equipment. If you are not sure of the
proper static control precautions, contact your nearest sales or service
representative.
NOTE:
The GranDSLAM is equipped with an ESD jack located near the upper-right
corner on the front of the chassis.
The MCP card is installed in Slot 9. The SCM card is installed in Slot A. DSL cards
can be installed in any one of Slots 1 through 8 and 10 through 18. However, if you
have only one DSL card, it is recommended that you begin with Slot 1.
NOTE:
It is important to completely secure each card in place before installing the
next card (tighten upper and lower screws). This is required to ensure proper
pressure on the EMI gaskets and to maintain proper air flow.
