240 Rack Mounting and Option Installation Appendix B
Installing the Cable Tray
The HP E840xA Cable Tray (Option 914) allows you to route VXI
instrument cables and wires under the mainframe. The cable tray can be used
when the mainframe is on a bench top or when mounted in a standard EIA
cabinet. The tray is compatible with the support rail (HP E3664A) and rack
slide (HP p/n 1494-0411) kits.
Note
If you ordered the support rail (HP E3664A) or rack slide (p/n 1494-0411)
kit, install the cable tray before rack mounting the mainframe.
Parts List
The parts included in Option 914 are shown in Table B-3.
Procedure
1. Remove the four mainframe feet by lifting the tabs and moving each
foot towards the center of the mainframe.
2. Attach the cable tray to the mainframe as shown in Figure B-11 using
four m5x8 pan head screws. Select the tray holes based on the amount
of cable clearance required.
The bottom mounting holes position the tray over one additional EIA
rack unit (44.5 mm), the top holes position the tray over two EIA rack
units, and the center holes position the tray between one and two EIA
rack units.
Note
If the mainframe is mounted extending out from the rack, install the cable
tray with the notched end at the front of the mainframe.
3. If the mainframe will be placed on a bench top, attach the mainframe
feet to the cable tray. If the mainframe is to be rack mounted, you can
save rack space by leaving the feet off.
