The ASR9000 supports a variaty of optic (types) including LAN and WAN phy, DWDM and tunable DWDM optics.
These optics all have different environmental specifics and with the support of high powered optics (that is the ones that consume more
then 1W nominal) there are some restrictions when it comes to the ports that they can be inserted on for the 24x10 or 36x10 next generation
high density linecards.
This pertains specifically to the ASR9922 chassis and the ASR9010 chassis when using V1 fan trays (not to confuse with V1 power trays).
The following table depicts to which optics the restriction in this article applies to:
PID | REACH | Power | Release |
---|---|---|---|
SFP-10G-SR | 26m-400m | 1.0W | XR 4.2.0 |
SFP-10G-SR-X | 26m-400m | 1.0W | XR 4.2.0 |
SFP-10G-LR | 10km | 1.0W | XR 4.2.0 |
SFP-10G-LR-X | 10km | 1.0W | XR 4.2.0 |
SFP-H10GB-ACU7M | 7m | 1.0W | XR 4.2.1 |
SFP-H10GB-ACU10M | 10m | 1.0W | XR 4.2.1 |
SFP-10G-ER | 40km | 1.2W | XR 4.2.1 |
SFP-10G-ZR | 80km | 1.5W | XR 4.2.2 |
DWDM-SFP10G-XX.XX | 80km | 1.5W | XR 4.2.2 |
ONS-SC+-10G-C | 80km | 2.0W | XR5.1.1, In 423/434 with smu |
DWDM-SFP10G-C | 80km | 2.0W | XR5.2.2, smu 434 |
The purple marked optics require the v2 fan tray for additional and proper cooling.
For the highpowered (red marked) optics the following port restrictions apply for the 24x10 card:
V2 Fan-tray provides better chassis cooling. With V2 Fan-tray there are no port restrictions on high-powered optics on ASR9K with 24-port and 36-port linecards
Note that the V2 Fan tray is different from the "v2-chassis" (eg ASR9010-AC-V2). The chassis type refers to the power modules capacity of the power
shelves. The v1 power shelf has room for 3 modules, the V2 power shelf has room for 4 (due to a smaller form factor)
Also note that the v2 fan tray can operate with v1 power.
V2 FAN tray means that we have better airflow and cooling
V2 POWER shelf means we have a smaller form factor of the same brick providing room for more power bricks.
V2 fans consume a bit more power then v1 fans, so as long as your power budget is fine, you can run either v1 or v2 power shelves.
On 24*10G and 36*10G linecards only certain ports (see pictures below) will be allowed to use ZR/DWDM optics in presence of the SMU on ASR 9922 chassis with V1 Fan-tray.
Upon insertion of ZR/DWDM optic into a restricted port, an message will be displayed explaining the restriction
- The red-ports are not allowed with V1 fan-tray on 24 or 36*10G with high powered optics. Regardless of how many are used. These restrictions are software enforced that doesn't evaluate "balancing" in terms of using one port/slot and not another.
- Yes, you can plug-in SR/LR optics in the red-ports on the same slot while high-powered optics are plugged into green-ports
- No. the thermal dynamics from this chassis do not pose the same restrictions as the ASR9010 or ASR9922.
- No. The ASR9001 doesn't carry the 24x10 or the 36x10 linecards. The MPA's do not require additional cooling when higher powered optics are in use at this point.

I believe there's a mistake around "Port restrictions for the 24x10 card (XR 4.2.3 and XR 4.3.0)":
"For the highpowered (red marked) optics the following port restrictions apply for the 24x10 card:"
It is very difficult to understand the above sentence as there is some ambiguity to what is being referred. I suggest changing it to:
"Ports marked with red do not accept high powered optics (1.5W or more)."
Are there any power caveats for the ASR-9912?
Hi Xander,
When I´ve FANv2, can I put all ports in 24x10 LC with highpowered SFP, for example SFP-10G-ZR?
There is not power restriction for this?
regards,
correct, v2 trays provide the cooling necessary and lifts the port restriction situation described above.

Does the new ASR 9901 have the same issue? I can put a hi-power tuned optic or a pre-tuned optic in, but must use "transceiver permit pid all" in order for it to transmit light. It came with and is using 3 ASR-9901-FAN V01 fans.
Also, I'm still working with TAC on this, the 9901 won't let you tune the optic for some reason using the "controller dwdm0/0/0/x" command, it shows up as "controller preconfigure dwdm0/0/0/x".
