Installing and Removing the AXSM-XG Extender Connector

Removing Redundancy Connectors

Warning
Remove power from the MGX 8850/B or MGX 8830/B switch before removing RCONs. Connector pins
near the RCON have hazardous voltages.
To remove RCONs, perform the following steps:
Step1 Remove power to the chassis, either at the AC power supply or DC power source.
Step2 At the back of the chassis, remove back cards over the RCON.
Step3 Remove the filler bars over the RCON. (MGX 8830/B only)
Step4 Unscrew the RCON fasteners and lift the RCON off the mounting bar.
Step5 Replace the filler bars. (MGX 8830/B only)
Step6 Reinstall back cards.
Step7 Restore power.
Installing and Removing the AXSM-XG Extender Connector
The extender connector (MGX8950-EXTDR-CON) extends additi onal serial lines from the
AXSM-16-155-XG and AXSM-8-622-XG cards to the MGX 8950 backplane. Install or remove the
extender connector, as necessary, to satisfy the following requirements:
•Cisco MGX 8950—The MGX8950-EXTDR-CON must be installed on AXSM-16-155-XG and
AXSM-8-622-XG cards. The cards require the extender connector for proper operatio n.
•Cisco MGX 8850 or Cisco MGX 8830—The MGX8950-EXTDR-CON must not be instal led on
AXSM-16-155-XG and AXSM-8-622-XG cards. The extender connector can damage the
backplane.
Note Remember to observe antistatic precautions when handling circuit boards. These precautions include
using grounded wrist straps, antistatic bags, and antistatic work surfaces.

Installing the Extender Connector

To install the extender connector:
Step1 Place the AXSM-16-155-XG or AXSM-8-622-XG card on a flat antistatic surface.
Step2 Locate an extender connector (MGX8950-EXTDR-CON) and mounting hardware. Usua lly, the
mounting screws and washers are attached to the connector itself. If they are, remove them.
Step3 Insert the extender connector into the connector on the AXSM-16-155-XG or AXSM-8-622-XG card
edge (see Figure 6-16).
