Hot-Swap Switch
A hot-swap switch is located on the bottom of the PPM behind the bottom locking ejector
handle. It is a normally open switch that is integrated with the bottom ejector latch mechanism
so it reflects the state of the latch. The switch is connected (closed) when the ejector latch is
fully inserted into the module and locked.
When the bottom ejector latch is opened, a signal is sent to the IPMC which causes the blue
hot swap LED on the front panel to blink. When the LED is solid blue, the PPM is ready to be
hot-swapped in the shelf. With hot-swapping, a module can be removed and reinserted in a
shelf without resetting the module.
PPM40 RTM
The PPM40 supports the PPM40 RTM, which connects to the back of the TD140 chassis
(
). Compliant with
PICMG 3.0 Advanced Telecommunications Computing
Architecture R3.0
, the PPM40 RTM supplies maintenance and additional connectivity options
to the PPM40 blade.
Each RTM provides the PPM40 with twelve ports supporting SFP (small form-factor
pluggable) or SFP+ modules:
Eight ingress ports for connection to monitored network
Four egress ports for connection to G10 probes
