SERVSWITCH™ SUMMIT
Take these steps to install a cascaded system with multiple Base Units:
1. Connect one end of a CAT5 UTP cable to user port # 1 on the back of the
master Base Unit. (If the cascade consists of both 16 x 64 Base Units and
other Base Unit models, a 16 x 64 Base Unit must be the master.) Connect
the other end of the cable to the RJ-45 CAT5 port on the back of the USM.
Connect a PS/2 keyboard, PS/2 mouse, and VGA monitor to the USM. (In an
all-PC installation, almost any PS/2 compatible pointing device should work
as long as all of the attached PCs have a driver for it.) Don’t plug in or turn
on the USMs or monitors yet. (Don’t attach anything to the Base Unit’s
channel ports, and don’t plug it in or turn it on yet either.)
2. For each subsidiary Base Unit you want to attach directly to the master, run
CAT5 UTP cables from consecutive channel ports on the master Base Unit to
the subsidiary Base Unit’s user ports.
3. If you’re installing a third tier: Run CAT5 UTP cables from consecutive channel
ports on a second-tier Base Unit to the user ports on a third-tier Base Unit.
Repeat for all other subsidiary Base Units in the third tier.
4. Follow step 5 in the single-Base-Unit installation (see Section 4.2) to attach
CIMs and CPUs to the channel ports of any third-tier Base Units, any free
channel ports on your second-tier Base Units, and any free channel ports on
your master Base Unit.
5. Following step 1 of the single-Base-Unit installation (see Section 4.2), plug in
and turn on any third-tier Base Units, then plug in and turn on your second-
tier Base Units, then plug in and turn on your master Base Unit. Following
steps 2b, 2c, and 2e of the single-Base-Unit installation, plug in and turn on
your USMs and monitors.
The master Base Unit should automatically recognize the connected
subsidiary Base Units and update its configuration automatically. All monitors
should display the Login Menu (see Figure 4-3 in Section 4.2). If any
monitors instead display a “.....No connection to Summit.....” message, the
USM they’re attached to isn’t properly connected to the master Base Unit.
Check for loose connections and make sure you’re using good, intact CAT5
cables. (See Appendix F for UTP-cabling information.)
NOTE
If your video image is fuzzy (especially if you’re using an LCD flat-
panel monitor), you can adjust the video gain to focus the video
image. If the OSUI isn’t already on screen at a given monitor, activate
it by pressing the [Scroll Lock] key twice rapidly, then use the
numeric keypad’s “+” and “–” (plus and minus) keys to adjust the
video image until it appears to be in focus.
