Installing Expansion Interface circuit packs
You must replace any expansion interface circuit packs in the PPN.
● If the existing PPN has TN776 or TN570 Expansion Interface circuit packs, you must
replace them with a TN570B Expansion Interface vintage 7 or later circuit pack.
● If this system includes an Enterprise Survivable Server (ESS), replace the circuit packs
with a TN570D or later Expansion Interface circuit pack.
To install the Expansion Interface circuit packs:
1. Remove the existing circuit pack.
2. Place the circuit pack in an antistatic carrier or bag.
3. Insert the TN570B Expansion Interface vintage 7 or later circuit pack into the EXPN INTFC
slots (A01, A02).
4. Repeat Steps 1 and 2 for each PN that does not contain TN570B Expansion Interface
vintage 7 or later circuit packs.
Completing circuit pack replacement
For standard (duplex) reliability configurations, repeat Duplex reliability configuration on
page 717 for each port network that receives a TN2312BP.
For high-reliability and critical-reliability configurations, repeat High-reliability or critical-reliability
configuration on page 720 and Connecting the CAT5 cables to the IPSI circuit packs on
page 722 for each port network that receives a TN2312BP.
