Replacing a U773 12-Port Fibre Channel Switch 1-1
Chapter 1
Replacing a U773 12-Port Fibre Channel
Switch1-
The U773 12-Port Fibre Channel Switch connects an ftServer V Series system to an
ftScalable Storage system (D916) or an FC JBOD system (D910). This document
describes how to remove and replace a switch.
The replacement procedure assumes that the existing system installation meets
configuration specifications.
The U773 12-Port Fibre Channel Switch
U773 fibre channel switches are housed in an Emulex tray and secured to the tray by
a Stratus-supplied AK-000576 (revision 001) mounting hardware kit. The bracket in the
kit allows for the removal of either switch while the system is online. When replacing a
U773 switch that is not secured by an AK-000576 kit, you must take the system off-line
because you must remove both switches and the tray. Before being secured by the
AK-000576 kit, the switches were secured to the tray by screws located on the bottom
of the switches, which you cannot access while the switch is mounted in the cabinet.
The procedures for removing and replacing a switch are as follows:
•“Replacing a Switch Secured Directly to an Emulex Tray” on page 1-2
•“Replacing a Switch Secured by the AK-000576 Kit” on page 1-13

Replacing a Switch Secured Directly to an Emulex Tray
Tool needed: #2 Phillips-head screw driver.
Since you must shut down the system to replace a U773 fibre channel switch that is
mounted in an Emulex tray, schedule system downtime before performing this
procedure.
To replace the switch
1. Shut down the system by issuing the shutdown command on the ftServer system
to be shut down.
For detailed information about starting up and shutting down your system, see the
VOS System Administration: Starting Up and Shutting Down a Module or
System
(R282).
2. Label all of the cables and cords from both switches (C, A1, R1, etc.), as shown in
Figure 1-1 and Figure 1-2. Figure 1-1 shows an ftScalable Storage system (D916)
and Figure 1-2 shows an FC JBOD system (D910) in Stratus-supported
configurations, but individual installations may differ.
3. Unplug all Ethernet and Fibre Channel cables from both switches.
4. Unplug the AC cords from both switches.

5. At the rear of one side of the system, remove the four screws (item 1 in Figure 1-3)
from the rear bracket, which connects to the tray.
On the outer side of the bracket is a flat, four-holed nut plate (item 2) that becomes
detached when you remove the four screws on the side. Hold the nut plate with
your fingers to prevent it from falling into the cabinet and remove the plate when
the four screws are removed.
Repeat this step for the corresponding screws and nut plate on the other side of
the system.

8. Remove the switches from the tray. Set the failed switch aside and place the good
switch and the replacement on a flat, stable surface.
9. Upgrade the Emulex tray with the AK-000576 kit (Figure 1-6). The kit comes with
6 screws: 4 for the rear bracket and 2 black screws for the front bracket.
Figure 1-6. AK-000576 Kit
a. At the front of the system, put the empty tray into the cabinet, supporting it by
placing your left hand beneath the tray and inserting and tightening the screws
into the front rails with your other hand.
Use only the top and bottom screw holes on each side to secure the four
screws, as shown in Figure 1-7.
