Online Insertion and Removal of the Cisco uBR-MC3GX60V-RPHY Line Card
You can replace a Cisco uBR-MC3GX60V-RPHY line card with only a Cisco uBR-MC3GX60V-RPHY line card.
-
Save the Cisco uBR-MC3GX60V-RPHY line card configurations before starting the OIR.
-
Change the standby card (if available) to HOT state.
-
Save the startup configuration file before any reload of the system (if there is a need to reload), after a successful OIR.
-
Perform OIR when the Cisco CMTS is up and running.
Step 1 | Enter the
cr10k
card
oir-compatibility command for the existing
Cisco uBR-MC3GX60V-RPHY line card.
Example: Router(config)# cr10k card 8/0 oir-compatibility This command preserves the configuration and performs internal synchronization to ensure that the OIR runs successfully. |
Step 2 | Save the
configuration to ensure the transition.
Example: Router# copy running-config startup-config |
Step 3 | Power down the
existing
Cisco uBR-MC3GX60V-RPHY line card using
cable
power
off command.
Example: Router# cable power off 8/0 Line Card 8/0 is POWERED OFF This powers off the Cisco uBR-MC3GX60V-RPHY line card gracefully. |
Step 4 | Before removing the existing Cisco uBR-MC3GX60V-RPHY line card, verify that the proper grounding instructions have been followed. |
Step 5 | Remove the existing Cisco uBR-MC3GX60V-RPHY line card from the slot. |
Step 6 | Install the new
Cisco uBR-MC3GX60V-RPHY line card in the slot.
See Installing the Cisco uBR-MC3GX60V-RPHY Line Card in the Card Slot. |
Step 7 | Power up the new
Cisco uBR-MC3GX60V-RPHY line card using the
cable
power
on command.
Example: Router# cable power on 8/0 |
Step 8 | Verify that the
new
Cisco uBR-MC3GX60V-RPHY line card and line protocol is up
using the
show
interface
cable command.
Example: Router# show interface cable 8/0/0 Cable8/0/0 is up, line protocol is up Hardware is BCM3210 ASIC, address is 010a.13e8.1ca8 (bia 010a.13e8.1a60) Internet address is 192.1.1.3/24 MTU 1500 bytes, BW 27000 Kbit, DLY 1000 usec, rely 255/255, load 1/255 Encapsulation, loopback not set, keepalive not set ARP type: ARPA, ARP Timeout 04:00:00 Last input 4d07h, output 00:00:00, output hang never Last clearing of "show interface" counters never Queuing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 1834000 bits/sec, 2385 packets/sec 5 minute output rate 1982000 bits/sec, 2431 packets/sec 24461542 packets input, 2348214388 bytes, 0 no buffer Received 1979 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 24854257 packets output, 2536222931 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 output buffer failures, 0 output buffers swapped out |
Step 9 | Verify the
hardware status using the
show
controllers
cable command.
Example: Router# show controllers cable 8/0/0 Cable8/0/0 JIB hardware status: JIB Downstream port Enabled JIB Upstream port 0 Enabled JIB Upstream port 1 Enabled JIB Upstream port 2 Enabled JIB Upstream port 3 Enabled Cable8/0/0 Upconverter is Enabled Output is Enabled |
Step 10 | Verify the configuration with the show running-configuration command. |
