Install OLIU circuit packs in Function slots

Procedure 4-3: Install OLIU circuit packs in Function slots

Overview

Use this procedure to install the following OLIU circuit packs in Function/Growth slots D1/D2 and G1/G2:

LNW31 OC-48 OLIU
LNW36 OC-3 OLIU

The LNW36 is DA'd and is no longer available
LNW37 4OC-3 OLIU with up to four pluggable transmission modules

The LNW37 is DA'd and is no longer available
LNW45 8OC-3 OLIU with up to eight pluggable transmission modules
LNW46 OC-12 OLIU
LNW49 4OC-12 OLIU with up to four pluggable transmission modules
LNW55 OC3/OC12/OC48 OLIU with up to twelve pluggable transmission modules
LNW62 4OC-48 OLIU with up to four pluggable transmission modules
LNW402 OC-48 OLIU with one pluggable transmission module
LNW421–459 OC-48 PWDM OLIU

The LNW421, LNW423, LNW431, LNW433, LNW435, LNW437, LNW443, LNW445, and LNW457 circuit packs are DA'ed and are no longer available.

Important!

If installing LNW55 and/or LNW62 OLIU circuit packs, the Main slots must be equipped with Very Large Fabric LNW84 or LNW141 OLIU circuit packs. If the Main slots are not equipped with Very Large Fabric OLIU circuit packs, the system reports a CP not allowed - eqpt alarm.

Equipage guidelines (Main slots not equipped with Very Large Fabric OLIU circuit packs)

If the Main slots are not equipped with Very Large Fabric LNW84 or LNW141 OLIU circuit packs, the OLIU circuit packs in a Function/Growth group must both have the same optical line rate and VT cross-connect size. For example, the LNW36 and LNW37 OC-3 OLIU circuit packs have the same optical line rate (OC-3) and VT cross-connect fabric size (up to 12 STS-1s); therefore, they can be used together in the same Function/Growth group. If the circuit packs in a Function/Growth group have different optical line rates or VT cross-connect sizes, the system reports an unexpected CP type alarm and service may be impacted.

The following is a list of low-speed OLIU circuit packs grouped by optical line rate and switch fabric size:

OC-3 OLIUs with 12 STS-1 switch fabric: LNW36, LNW37
OC-3 OLIUs with 48 STS-1 switch fabric: LNW45
OC-12 OLIUs with 12 STS-1 switch fabric: LNW46
OC-12 OLIUs with 48 STS-1 switch fabric: LNW49
OC-48 OLIUs with 12 STS-1 switch fabric: LNW31, LNW402, LNW421–459

The LNW421, LNW423, LNW431, LNW433, LNW435, LNW437, LNW443, LNW445, and LNW457 circuit packs are DA'ed and are no longer available.

Equipage guidelines (Main slots equipped with Very Large Fabric OLIU circuit packs)

If the Main slots are equipped with Very Large Fabric LNW84 or LNW141 OLIU circuit packs, the circuit packs in a Function/Growth group may be the same or different circuit pack type depending on the Slot Protection State.

If the Slot Protection State is Protected, the OLIU circuit packs/ports in a Function/Growth group must both have the same optical line rate and VT cross-connect size. When any OLIU circuit pack, except an LNW55 OLIU circuit pack, is installed in an unprovisioned Function/Growth group, the default Slot Protection State is Protected. When an LNW55 OLIU circuit pack is installed in an unprovisioned Function/Growth group, the default Slot Protection State is Unprotected.

If the Slot Protection State is Unprotected, the circuit packs within the Function/Growth group may be different circuit pack types. The default Slot Protection State is Unprotected when an OLIU circuit pack is installed in a Function/Growth group with an unprotected circuit pack.

The following combinations of 0x1 compatible circuit pack types are supported in Function/Growth Slot 1 and Slot 2 when the Slot Protection State is Unprotected.

Slot 2	Slot 1
Slot 2	LNW66/LNW71	LNW74 (S1:2 and later)	LNW70 (S1:3 and later)/ LNW78	Other Front Access Circuit Packs¹
LNW66/LNW71	Not compatible	Not compatible	Not compatible	Compatible
LNW74 (S1:2 and later)	Not compatible	Compatible²	Compatible	Compatible
LNW70 (S1:3 and later)/ LNW78	Not compatible	Compatible	Compatible	Compatible
Other Front Access Circuit Packs¹	Compatible	Compatible	Compatible	Compatible

Notes:

This includes the LNW63, LNW64, LNW67, LNW68, LNW73/73C, LNW87, LNW170, LNW785, and all low-speed OLIU circuit packs. The LNW6, LNW7, LNW8, LNW16, LNW18, LNW19/19B, LNW20, LNW39, LNW70 (S1:2 and earlier), LNW74 (S1:1), LNW391, LNW801, LNW111, and LNW112 are not 0x1 compatible.
The circuit pack Ethernet Mode parameter must be provisioned as FX to support LNW74 circuit packs in slot 1 and slot 2; otherwise, this configuration is incompatible.

If an incompatible circuit pack is installed in a Function/Growth slot, the system reports a CP not allowed - eqpt alarm.

Select View → Equipment to access the circuit pack details and determine the value of the Slot Protection State parameter.

The Slot Protection State parameter can be changed from Protected to Unprotected or from Unprotected to Protected. If required, refer to Procedure 4-23: Change slot protection state.

The LNW421, LNW423, LNW431, LNW433, LNW435, LNW437, LNW443, LNW445, and LNW457 circuit packs are DA'ed and are no longer available.

Are you installing an LNW421–459 OLIU circuit pack?

If...	Then...
Yes	Continue with Step 5.
No	Proceed to Step 8.

From your work orders, determine the wavelength that you wish to set on the LNW421–459 circuit pack. Use the Channel Select Option Label on the faceplate of the circuit pack to determine the correct channel.

Example

From the Channel Select Option Label on the faceplate of the LNW447, refer to Figure 4-1, Channel select option label on LNW447, we determine that for the desired CH47 wavelength, we must select CH X.

Figure 4-1: Channel select option label on LNW447

Set the channel selection jumper on your circuit pack to either CH X or CH Y for your desired wavelength/channel, refer to Figure 4-2, Jumper settings for LNW421–459.

Figure 4-2: Jumper settings for LNW421–459

Using an erasable marker or pencil, check the appropriate box on the Channel Select Option Label, refer to Figure 4-1, Channel select option label on LNW447, that corresponds to your jumper setting.

Important!

This label is the only means available to identify the wavelength selected when the pack is fully seated and/or in-service.

Important!

If required, verify that the shelf is equipped with the deeper shelf cover and carefully remove any caution tags that are attached to the LNW55 circuit pack.

Holding the OLIU circuit pack vertically, rotate the OLIU circuit pack 90 degrees to the right (clockwise). The faceplate label with LNW( ) should be on your right, next to the fan unit.

Open both faceplate latches and seat the OLIU circuit pack into the required Function/Growth slot by applying steady pressure to both faceplate latches.

Result:

For LNW55 OC3/OC12/OC48 and LNW62 4OC-48 OLIU circuit packs, the FAULT LED lights for approximately 10 minutes then goes off, indicating successful installation.
