Installation
ciscoBus Controller Card LEDs
Depending upon whether you installed a CSC-MEC or a CSC-C2MEC, you will check the following
ciscoBus controller card:
•
•
The ciscoBus controller card (CSC-CCTL or CSC-CCTL2) is always installed in the center
ciscoBus slot (Multibus slot number 7) as shown in Figure 8.
Following are LED descriptions for both ciscoBus controller cards.
Figure 13 illustrates the LEDs that are on when a card is present in a corresponding ciscoBus slot.
(The orientation of Figure 13 is looking at the front edge of the card installed in the card cage.) The
numbers above the LEDs indicate the ciscoBus slot numbers. Depending upon the slot in which the
ciscoBus card is installed (slot 0 through 3), the corresponding LED will be on to indicate a card in
that slot. Some ciscoBus cards have appliques that require power from the card to which they attach.
If these appliques are not connected correctly, the corresponding LED on the CSC-CCTL will not
be on. All other LEDs are on momentarily at power on, but are not currently used.
Figure 13
The LEDs on the CCTL2 card indicate when an interface is present in a ciscoBus slot. The front edge
of the CCTL2 card contains a bank of five LEDs as shown in Figure 14. (The orientation of
Figure 14 is looking at the front edge of the card installed in the card cage.) There is one red LED
for each interface slot in the ciscoBus, and a green LED to indicate a successful boot procedure. One
red LED will be on for each correctly connected ciscoBus card using the correct version of
microcode. It will not be on if the card is incorrectly connected or if the microcode on that ciscoBus
card is the wrong version. The numbers above the LEDs (0 through 3 from right to left) indicate the
ciscoBus slot numbers.

22 Installing the CSC-MEC and CSC-C2MEC Multiport Ethernet Controller Cards
If you installed a CSC-MEC (first-generation ciscoBus interface card), check the LEDs on the
CSC-CCTL ciscoBus controller card.
If you installed a CSC-C2MEC (second-generation ciscoBus interface card), check the LEDs on
the CSC-CCTL2 ciscoBus controller card.
