Connecting and Testing a Switching Plane Between a T640 Router and TX Matrix Router
 | Caution: While you install the TX Matrix router or replace a fiber-optic array cable, small deposits of oil, dust, and debris can enter the TX-SIB and T640-SIB fiber-optic array adapters, the fiber-optic array cable connectors, and the loopback connectors and adapters. We recommend that you clean the optics in these components, as well as the loopback connector and adapter dust covers, immediately before connecting them. For cleaning instructions, see Cleaning the TX Matrix and T640 Fiber-Optic Components Overview. |
After you convert a switching plane from a SIB to a T640-SIB, you connect a fiber-optic array cable to it and test it using the following procedure (see Fiber-Optic Array Cable Connections between TX-SIBs and T640-SIBs for the T640-SIB adapter connections):
- Using the labels you attached to the ends of the fiber-optic array cables, identify the cable that plugs into the T640-SIB.
- Remove the dust cover from the fiber-optic array cable connector by loosening the thumbscrew and captive screw on the connector. (Use the supplied small slotted screwdriver to loosen the captive screw.) Store the dust cover in a dust-free resealable plastic bag.
- With the fiber-optic array cable extending toward the left side of
the chassis (as you face the rear), align the cable connector with
the T640-SIB adapter and carefully press it into the adapter until
it stops. The cable connector and adapter are keyed to ensure proper
mating.
Note: The optics in a fiber-optic array adapter are spring loaded, so you must continue to apply force to a fiber-optic array cable connector or loopback connector while securing it to a TX-SIB or T640-SIB adapter.
- Partially tighten the thumbscrew and captive screw on the fiber-optic array cable connector. (Use the supplied small slotted screwdriver to tighten the captive screw.) Alternate between the thumbscrew and captive screw until the cable connector is secured to the adapter.
- On an external management device connected to the console or
auxiliary port of the T640-CIP, bring the T640-SIB online using one
of the following methods:
- Press and hold the ONLINE/OFFLINE button on the T640-SIB faceplate until the OK LED blinks.
- Issue the request chassis sib online command.
For example:
user@host> request chassis sib online slot 0
- On an
external management device connected to the console or auxiliary port
of the TX-CIP, enable the TX-SIB fiber-optic array adapter receivers
by issuing the request chassis sib slot start-receiver scc command. For example, if you are enabling adapter LCC0 on TX-SIB-0, issue the following command:
user@host> request chassis sib slot 0 start-receiver 0 scc - On an external
management device connected to the console or auxiliary port of the
T640-CIP, enable the T640-SIB fiber-optic array adapter receivers
by issuing the request chassis sib slot start-receiver command.
For example, if you are enabling the adapter on T640-SIB-0, issue the following command:
user@host> request chassis sib slot 0 start-receiver 0 - Verify that the RX LED next to the TX-SIB adapter is steadily lit green.
- Verify that the RX LED next to the T640-SIB adapter is steadily lit green.
- If the RX LEDs next to the TX-SIB adapter and T640-SIB
adapter are steadily lit green, the connection between the TX-SIB
and T640-SIB is operating correctly.
If the RX LEDs next to the TX-SIB adapter and T640-SIB adapter are not steadily lit green, disable the TX-SIB and T640-SIB adapter receivers, disconnect the fiber-optic array cable connector from the T640-SIB, and clean it and the T640-SIB adapter:
- To disable the adapter receivers, issue the request
chassis sib slot stop-receiver scc and request chassis sib
slot stop-receiver commands on the TX Matrix router and
T640 router. For example, if you are disabling the adapters on TX-SIB-0 and T640-SIB-0, issue the following commands
on the TX Matrix router and T640 router:
user@host> request chassis sib slot 0 stop-receiver 0 sccuser@host> request chassis sib slot 0 stop-receiver 0 - To disconnect the cable connector, partially loosen its thumbscrew and captive screw. (Use the supplied small slotted screwdriver to loosen the captive screw.) Alternate between the thumbscrew and the hex screw until the cable connector is removed from the adapter.
- For instructions aboutcleaning the fiber-optic array cable connector and T640-SIB adapter, see Cleaning the TX Matrix and T640 Fiber-Optic Components Overview.
- To disable the adapter receivers, issue the request
chassis sib slot stop-receiver scc and request chassis sib
slot stop-receiver commands on the TX Matrix router and
T640 router. For example, if you are disabling the adapters on TX-SIB-0 and T640-SIB-0, issue the following commands
on the TX Matrix router and T640 router:
- Reconnect the fiber-optic array cable connector and T640-SIB adapter as described in Step 3 through Step 4.
- Enable the TX-SIB and T640-SIB adapter receivers.
user@host> request chassis sib slot slot-number start-receiver interface-number sccThe slot number can be from 0 through 4 and corresponds to the TX-SIB chassis slot. The interface number can be 0 through 3 and corresponds to the TX-SIB adapters labeled LCC0 through LCC3.
- Verify that the RX LEDs next to the TX-SIB
adapter and T640-SIB adapter are steadily lit green, indicating that
the connection between the TX-SIB and T640-SIB is operating correctly.
If the RX LEDs next to the TX-SIB adapter and T640-SIB adapter are not steadily lit green, contact your customer support representative for additional instructions. Do not proceed with the installation of the TX Matrix router until you have spoken to your customer support representative.
- Repeat the procedures described in Converting a Switching Plane in a T640 Router and this procedure for each remaining SIB in the T640 router.
