20 8000 Series DC power supplies
313070-E Rev 00
Table 2 describes the power supply LED on the DC power supply.
Note: The 8010co equipment shelf load and 8004DC power rating shall
be limited to 732w per power supply when configured with the 8010co
BIP. The product configuration limitation is required to be in
compliance with the electrical code, because of the difference between
the 8010co BIP output circuit protection rating of 30A and the 8004DC
power supply input current rating of 29A at -48Vdc nominal operating
condition.
Note: The 8002DC power supply is discontinued. The 8004DC or
8005DC power supply replaces the 8002DC power supply.
Caution: The 8004DC and 8005DC power supplies have different
power ratings. Therefore, Nortel recommends that you do not operate the
Ethernet Routing Switch 8600 chassis with a mix of power supply
models.
If you are upgrading the Ethernet Routing Switch 8600, and have a
redundant power configuration, you can hot-swap the 8004DC power
supply with the 8005DC power supply while the Ethernet Routing
Switch 8600 system remains in operation. Do not operate the chassis
with a mix of power supply models for an extended period of time.
Upgrade power supplies before upgrading modules.
