Cabling the AT-StackQS Card with Fiber Optic Transceivers
This section contains the procedure for cabling AT-StackQS Cards with
AT-QSFPSR and AT-QSFPLR4 Transceivers. For instructions on
installing the cards in switches, refer to Chapter 5, “Installing AT-StackQS
and AT-x9EM/XT4 Cards” on page 103
If you are using the ports on the card for the VCStack trunk, review the
guidelines in “Trunks of AT-StackQS Cards” on page 64 before performing
this procedure.
For the maximum operating distances and cable requirements of the
transceivers, refer to the
x930 Data Sheet
on the Allied Telesis website for
the list of supported transceivers for the AT-StackQS card.
The transceivers are hot-swappable. You can install them while the
switches are powered on.
To cable the AT-StackQS Cards with fiber optic transceivers, perform the
following procedure:
1. Remove the dust cover from one of the ports on the AT-StackQS
Card.
2. Slide a transceivers into the port until it clicks into place.
3. Attach a fiber optic cable to the transceiver.
4. Repeat this procedure to install and cable a transceiver in the second
port.
5. If you are using the cards for the VCStack trunk, install and cable
cards in the other switches of the stack. The connections must
crossover on the switches. Port 1 on the card in one switch must be
connected to port 2 in the next switch.
6. If you are using the cards for the VCStack trunk, go to Chapter 12,
“Building the Stack with AT-StackQS Cards” on page 159 after cabling
all the switches.
