HP DC SAN Backbone Director Switch Hardware Reference Guide (5697-2158, August 2012)

Replacing a Director blade
This section describes how to remove and replace a Director blade.
The replacement procedure for each Director blade takes less than ten minutes. The following items
are required for the Director blade and filler panel replacement:
• ESD grounding strap
• Workstation computer
• Replacement Director blade or filler panel
• Phillips screwdriver
• SFP or 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 (page 62).
2. A failed port or Director blade can be identified by inspecting the LEDs on the front panel of
each blade. Observe the power LED, status LED, and port status LED to identify any possible
problems. See Monitoring DC Director system components (page 43) 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. Verify 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.
9. FC8-16, FC8-32, FC8-48, FC8-64, FS8-18, FX8-24, FCOE10-24 blades: Adjust the ejectors
to the open position. Use the Phillips screwdriver to unscrew the two thumb screws from the
top and bottom ejectors on the blade. See Figure 34 (page 65).
Unscrew the top thumb screw until it pops out. This initiates a hot-swap request.
FC10-6 and FR4-18i blades: Power off the blade by sliding the slider switch in the top ejector
down, to the off position. This initiates a hot-swap request.
10. Wait for the power LED to turn off in response to the hot-swap request before removing the
blade.
