Chapter 14 Power Down a Node
NTP-G119 Power Down the Node
b. If the node is not connected to a working network and the current configurations are no longer
required, proceed to Step 4.
Note Before the power-down of a DWDM node, the fiber spans connected around it must be
disconnected from the network. This is to prevent the accidental disconnection of
wavelengths that pass through the shelf. A good indication that the shelf has been
disconnected from the network is optical service channel (OSC) alarms, or no OSC channels
provisioned.
Note Current configurations will be saved if Steps 4 to 16 are skipped.
Step 4 In node view, click the Circuits tab and verify that no circuits appear, then proceed to Step 5. If circuits
appear, delete all the circuits that originate or terminate in the node. Complete the “DLP-G106 Delete
Optical Channel Network Connections” task on page 7-12 or the “DLP-G112 Delete Overhead Circuits”
task on page 7-22 as needed.
Note When deleting circuits from a node, make sure that the node is not connected to any network.
Step 5 In node view, click the Provisioning > Protection tabs and delete all protection groups:
a. Click the protection group that needs to be deleted and click Delete.
b. Click Yes .
Repeat until no protection groups appear.
Step 6 In node view, click the Provisioning > Comm Channels tabs and delete all communications channel
terminations:
a. Click the section data communications channel (SDCC), line data communications channel
(LDCC), generic communications channel (GCC), or OSC termination that needs to be deleted and
click Delete.
b. Click Yes .
Repeat until no SDCC, LDCC, GCC, or OSC terminations are present.
Note Before deleting the OSC termination, make sure the Ring ID is deleted. Click the Provisioning
> Comm Channels > OSC tabs. Select the Ring ID and click Delete.
Step 7 Before deleting any installed DWDM cards, the optical patch cords have to be deleted. In the node view,
click Provisioning > WDM-ANS > Connections tabs.
a. Select all the connections and click Delete.
b. Click Yes .
Step 8 For each installed MSTP channel-bearing card (AD-1C-xx.x, AD-2C-xx.x, and AD-4C-xx.x, where xx.x
refers to the specific wavelengths), make sure all lines and bands are not in IS-NR (ANSI) or
Unlocked-Enabled (ETSI) service state:
a. In the card view, click the Provisioning > Optical Line > Parameters tabs.
b. In the Admin State column for each line, make sure that the default state IS, AINS (ANSI) or
Unlocked,automaticInservice (ETSI) is selected.
