The HCM in the slot labeled HCM0 is paired with the Routing Engine in the slot labeled
RE0. Likewise, the HCM in the slot labeled HCM1 is paired with the Routing Engine in the
slot labeled RE1. By default, the HCM in the slot labeled HCM0 is the master. However,
in this instance, the Routing Engine in slot RE1 has taken over mastership, indicating that
the HCM in slot HCM1 is also master.
NOTE: Although steps to remove and install an HCM are provided here, ensure
that you refer to the appropriate hardware guide for the latest information.
Before performing a swap test, always check for bent pins in the midplane
and check the HCM for stuck pins in the connector. Pins stuck in the
component connector can damage other good slots during a swap test.
The HCM is hot-pluggable. You can perform a swap test on an HCM to pinpoint the
