Switch Control Module Reference
The CSS 11500 series Switch Control Module (SCM) provides master control and is responsible for the
following functions: system powerup and boot control, centralized routing table management,
system-wideconnection management,and interface toanexternal NetworkManagementStation.
Figure1shows an SCM (CSS5-SCM-2GE=).
Figure1SCMLEDs and Connectors
Only one SCM is required in a configuration, however you can install and configure a second SCM for
redundancy in a CSS 11506. A secondary SCM is passive, and does not load share processing functions
with the primary module. If the primary SCM fails, theCSS reboots and connections are terminated.
Thenthe secondary SCMbecomes primary automatically.

Note Beforeyou remove or install a module, make sure you properly ground yourself prior to handling the
module. For example,wearan antistaticwriststrap (included in the kit withthe module)and stick
the copper-tape end of the strap to an unpainted metal surface on the chassis. Make sure that the wrist
strap makes good contact with your skin.
Removing theSCM
Caution You must power down the CSS to removean SCM. If you remove a powered-on SCM from an
operational CSS, the CSS terminates all communications and reboots.
To remove anSCM:
1.Locatethe failed SCM (its Status LEDs willbe off). See Figure1.
2.If necessary, power down theCSS.
3.Remove all cablesfrom the module.
4.With a Phillips screwdriver, remove the PCMCIA cover and thenloosen the spring-loaded screws
on the frontof the modulefaceplate. See Figure2.

5.Extend both ejectors simultaneously to unseat themodule connector from the backplane and slide
the module out ofthe slot.

6.Remove the SFP GBICs from the SCM. Press the ejectors on the SFP GBICs. Slide them out of the
module and set them aside. See Figure3.

7.Remove the flash or hard disks from the SCM. Press the ejectors to the rightof the disks. Slide them
out of the module and set them aside. See Figure4.

Note Thereplacement SCM contains a 144 MB Small OutlineRamBus InlineMemory Module
(SO-RIMM). If your failed module has a288 MB SO-RIMM, you must remove its SO-RIMM, and
place it in the replacement SCM. See“Removing and Replacing the Memory Module” later in this
document.
Installingthe SCM
To install an SCM (refer to the previous illustrations):
1.Properly ground yourself prior to handlingthe module, as noted on the previous page.
2.If applicable, reinstallthe memory module, SFP GBICs, and flash or hard disks in the SCM.
3.Locate the slot in the chassis for the SCM. SCMs are restricted to slots 1 and 2.

4.Insertthe moduleinto the board guides atthe left and right sides of the slot, and then slidethe
module into the chassis bypressing firmly at the leftand right of the faceplate.
5.Close both ejectors simultaneously to seatthe moduleconnector into the backplane.
6.Using aPhillips screwdriver,tighten the spring-loaded screws on the front ofthe module faceplate.
7.With a Phillips screwdriver, replace the PCMCIA cover (see Figure2) and then tighten the
spring-loadedscrews on the front of the modulefaceplate.
8.Replace the cables. Note that the SFP GBICs haveLC-type connectors and require LC-type fiber
cables.
9.Reboot the CSS.
10.If you installed a secondary SCM, use the passive sync command to copy the boot config from the
primary SCM to the secondary SCM.
If you installed a replacement for a primary SCM,the replacementhas defaultsettings for the
administrative username and password, IP address, subnet mask, and primary boot record. To
reconfigure these parameters, access the Offline Diagnostic Monitor menu at the boot prompt. For
information on using the Offline Diagnostic Monitor menu, refer to the Content Services Switch
Administration Guide.
Table 1 describes the SCM LEDs and their indications.
Related CLI Commands
To view the current state of the SCM and verify it is powered on as indicated by the primary or secondary
state,use the show chassis command.

Removing and Replacingthe Memory Module
To remove and replace amemorymodule:
1.Place the modulefaceup on a flat antistatic surface.
2.Locate the SO-RIMM connector on the rear of the module. See Figure 5.
Figure5MemoryModule Location
3.Slightly extend the locking tabs on both sides of the memory module to release it. Gently pull the
module out of the connector. See Figure 6.
Figure6MemoryReplacement
4.Align the replacement memory module so that the rowof gold contacts on thememory module are
facingtherow ofgoldpins insidetheconnector.
5.Insertthe memory module into the connector at approximately a 30 degree angle (see Figure 6) and,
with gentle pressure, push the module into the connector until the module fits snugly against the
back of theconnector. At this point, themodule is still at an angle above the locking tabs.
6.Gently push straight down on the edges of the module until the tabs lock itinto place.
