SAN04B-R Installation, Service, and User's Guide
1. Verify that the replacement router is the correct part number (45W0154).
2. Verify that you know where the configuration backup file is stored for restoring
the configuration once the router replacement has been completed.
3. If you have not done so already, turn off the power to the router. (See
"Powering off the router" on page 38.) If you cannot run the sysShutdown
command, just switch off the two power supplies on the non-port side of the
router.
4. Unplug the power cords from the two power supplies. If desired for better
access, unplug the other end of the power cords from the power sources. Set
the power cords aside for use with the replacement router.
5. If you have not done so already, label each cable to simplify reconnecting the
cables to the correct ports. Make a written record of the cable configurations if
needed.
6. From the port side of the router, remove each cable one at a time from its SFP
(See "Removing fiber optic cables" on page 46).
7. From the port side of the router, remove each SFP. (See "Removing, and
installing SFPs" on page 44 for detailed instructions, if needed.) Set the SFPs
aside for later installation in the new router. Keep the two GbE SFPs separate
from the other SFPs to ensure installation in the correct ports.
8. Remove the router from the rack. Verify and remove any mounting hardware or
screws that prevent the router from being removed from the cabinet. If the
router is installed on sliding rails, press the release mechanism on the rails to
allow full removal of the router and inner rails.
9. Remove the rail hardware from the router. Set it aside for attachment to the
new router, making notes as necessary for the correct placement of parts.
(Refer to "Installing the router in a cabinet" on page 12 for illustrations and
complete rack mount instructions.)
with the replacement router.
1. Follow any instructions included with the CRU related to attaching labels, if
any.
2. Attach the rail hardware to the new router. Refer to your notes or "Installing the
router in a cabinet" on page 12, as needed.
3. Slide the router into the rails attached to the cabinet.
4. Attach any screws or hardware that you removed earlier to allow removal of
the original router.
5. Install the SFPs and connect the Fibre Channel cables, using the labels and
notes you made during the removal steps.
6. Provide power to the router. (Follow the instructions in "Providing power to the
router" on page 19.) The router will take several minutes to complete POST.
7. Create a serial connection to the router. (Follow the instructions in "Creating a
serial connection" on page 19.)
8. Set the router IP address. (Follow the instructions in "Setting the router IP
address" on page 20.)
