• Phillips screwdriver • Small form-factor pluggable (SFP) or extended form-factor pluggable (XFP, FC10-6 Director blade only) transceivers (as needed) • Optical cables (as needed) WARNING! A filler panel should be removed only when being replaced with a Director blade, or a filler panel. Any slot that is not occupied by a Director blade should be occupied by a filler panel to ensure correct cooling of the chassis and protection from dust. Removing a Director blade CAUTION: Wear a grounded ESD strap when handling a Director blade. Use the grounding connections above the power connectors on the chassis. 1. Remove the chassis door. See "Removing the chassis door" on page 73. 2. A failed port or Director blade can be identified by inspecting the LEDs on the front panel of each blade. Check the power LED, status LED, and port status LED to identify any possible problems. See "Monitoring DC Director system components" on page 57 for LED locations. 3. Establish a Telnet or console session. Before replacing a blade, establish a Telnet or console connection to determine a failure and verify operation after replacement. Use the switchShow command to view the status of blades. 4. Check for adequate cable slack. Ensure there is plenty of cable slack to remove a blade without cable obstruction. 5. Ensure that the part number on the unit being replaced matches the replacement part number. The chassisShow command displays information about the blades, including part numbers (xx-000xxxx-xx), serial numbers, and additional status. 6. Ensure that traffic is not flowing through the blade (port status LED should be off) prior to disconnecting cables. NOTE: Before removing any cables from a blade, note the cable order (identify each cable by its physical port). If multiple blades are being replaced, replace one blade at a time. 7. Ensure that traffic is not flowing through the blade. 8. Disconnect all cables and SFP or XFP transceivers from the blade. 76 Replacing DC SAN Director field-replaceable units (FRUs)

WARNING!
A filler panel should be removed only when being replaced with a Director blade, or a filler panel.
Any slot that is not occupied by a Director blade should be occupied by a filler panel to ensure
correct cooling of the chassis and protection from dust.
Removing a Director blade
CAUTION:
Wear a grounded ESD strap when handling a Director blade. Use the grounding connections above
the power connectors on the chassis.
1.
Remove the chassis door. See “
Removing the chassis door
” on page 73.
2.
A failed port or Director blade can be identified by inspecting the LEDs on the front panel of
each blade. Check the power LED, status LED, and port status LED to identify any possible
problems. See “
Monitoring DC Director system components
” on page 57 for LED locations.
3.
Establish a Telnet or console session.
Before replacing a blade, establish a Telnet or console connection to determine a failure and
verify operation after replacement. Use the
switchShow
command to view the status of blades.
4.
Check for adequate cable slack. Ensure there is plenty of cable slack to remove a blade without
cable obstruction.
5.
Ensure that the part number on the unit being replaced matches the replacement part number.
The
chassisShow
command displays information about the blades, including part numbers
(
xx
-000
xxxx
-
xx
), serial numbers, and additional status.
6.
Ensure that traffic is not flowing through the blade (port status LED should be off) prior to
disconnecting cables.
NOTE:
Before removing any cables from a blade, note the cable order (identify each cable by its
physical port). If multiple blades are being replaced, replace one blade at a time.
