6.3.2.2 I/O Rear Transition Card Set
The I/O rear transition card set consists of two separate cards:
The front I/O card (front)
I
The I/O rear transition card (rear)
I
The front I/O card contains the ASICs for the associated I/O card and is installed
from the front of the server; however, no cables are connected to the front I/O card.
The I/O rear transition card extends the ports for a particular I/O card to the rear of
the server. The I/O rear transition card and the front I/O card must be installed in
the same slot at the front of the server in order for the I/O rear transition card to
work. For example, if you install an I/O rear transition card in I/O slot 3 at the rear
of a Netra CT 810 server, you must also install the accompanying front I/O card in
I/O slot 3 at the front of the server.
When one of the two cards fails, you may not be able to determine which of the two
cards has failed. Because of this, you may want to replace both the front I/O card
and the I/O rear transition card.
representations of how the front I/O cards should align with the I/O rear transition
cards (RTCs). Note that, if you are facing the front of the server, the I/O slots read
from left to right, whereas they read from right to left if you are facing the rear of the
server.
