Chapter 5 Installing the Cisco MGX Switch or Gateway
First Time Power On Procedure for MGX Switches
Step 5 Insert in the back cards and console port cable for the primary PXM controller card. For example, on an
MGX 8850 (PXM45) chassis, the PXM-UI-S3 or PXM-UI-S3/B back card supports the PXM45 front
(controller) card. For this example, the primary PXM full-height card will be in slot 7 and 23 when
viewed from the front of the chassis. Then insert the half-height PXM-UI-S3 or PXM-UI-S3/B back card
in back of the chassis, in the top bay behind slot 7. The PXM-HD (hard disk) card would be inserted in
the back of the chassis, in the lower bay behind slot 23.
Step 6 Insert the primary PXM front card.
Step 7 Through the console port connection, monitor the primary PXM card as it comes up to Active status.
When the card is Active, the prompt will appear like n.7.PXM.a>.
• Use display environment statistics or alarm commands (dspenvalms or dspenvstats) to ensure that
all components such as power supplies and fans are running. See the following example:
