DLP-D247 Change an STM-N Card
Caution
Physically removing an STM-N card can cause a loss of working traffic or a protection switch. See
Chapter 12, “Upgrade Cards and Spans”
for information on upgrading traffic to a higher speed.
Note
You can replace a multiport card with a card with a smaller number of ports only if the new card has the
same line rate as the multiport card. (The MRC-12 card can be replaced with either a single-port STM-4
card or a single-port STM-16 card.)
Step 1
If the card is the active card in a 1+1 protection group, switch traffic away from the card:
a.
Log into a node on the network. If you are already logged in, go to Step
b.
Display the CTC node (login) view.
c.
Click the
Maintenance > Protection
tabs.
d.
Double-click the protection group that contains the reporting card.
e.
Click the active card of the selected group.
f.
Click
Switch
and
Yes
in the Confirmation dialog box.
Step 2
In CTC, right-click the card that you want to remove and choose
Change Card
.
Step 3
From the Change Card drop-down list, choose the card type and click
OK
. An MEA alarm appears until
you replace the card.
Step 4
Physically remove the card:
a.
Open the card latches/ejectors.
b.
Use the latches/ejectors to pull the card forward and away from the shelf.
Purpose
This task changes an STM-N card while maintaining existing provisioning,
including DCCs/generic communications channels (GCCs), circuits,
protection, timing, and rings. This task is intended to be used when you are
replacing a card with a card of identical type and line rate, when a slot is
preprovisioned and you want to change the optical speed of the card, or
when you have backed out of an automatic span upgrade.
