4 Engage the back shoulder screws into their respective J-slots.
5 Lower the front of the system and fit the middle and front shoulder screws into their respective J-slots.
6 Push the system inward on the mounting rails until the system-locking mechanism clicks into place,
locking the slide to the system.
7 Push in the release latches on the side of the slide assemblies, and push the system into the rack.
8 Tighten the thumbscrews on the system front panel to secure the system to the rack.
Cable Management
Use the cable tray and cable-management arm to manage your system’s I/O and power cables. Use the tie-
wraps on the cable tray to bundle the cables together. Use the cable-management arm to contain the cables
by routing them through the upper and lower wire baskets.
NOTE:
You can attach the cable-management arm to either side of the rack cabinet. If you attach the
cable-management arm to the right side of the rack cabinet, you can open both cable baskets without moving the
cable-management arm. If you attach it to the left side, you have to swing the cable-management arm out toward you
to open the cable baskets.
NOTE:
If you attach the cable-management arm to the left side of the rack, you must disconnect the lower release
latch on the cable-management arm before you can remove the power supply.
NOTE:
You will attach the cable-management arm retainer to the side opposite of where you attach the cable-
management arm.
Attaching the Cable Tray
To attach the cable tray to the back of the system:
1 Locate the tab slots on the left and right outer edges of the system and the corresponding metal tabs
on the left and right edges of the cable tray (see Figure 1-8).
2 Align and insert the metal tabs on the cable tray into the tab slots on the system and seat the cable tray
into place.
3 Push down and tighten the captive thumbscrew on the cable tray to secure it to the system
(see Figure 1-8).
CAUTION:
The cable tray cannot support the weight of the system. Do not grasp the cable tray when lifting
the system. Lift the system only by the chassis edges.
