There should details of the switch base card, the accelerator card if installed, and the type of power supply unit or fan only module installed. Both the part names and the serial numbers of the base card and accelerator card should be displayed. If there is no entry for the accelerator card then the switch’s boot process has not correctly detected the accelerator card’s presence.
Hardware Reference 29 Small Form Factor Pluggable (SFP) Transceivers AT-9900 Series switches have 1000BASE-X Small Form Factor Pluggable (SFP) uplink sockets on their front panel. The AT-9924T/4SP and AT-9924T have four SFP sockets and the AT-9924SP has 24 SFP sockets. Certain fibre and copper SFP transceivers are supported. This allows you to interchange port types to meet changing network requirements. SFP transceivers are hot swappable.
30 AT-9900 Series Switch SFP port and RJ-45 port operation On AT-9924T/4SP and AT-9924T switches, 24 ports are operational at one time out of a total of four SFP ports and 24 RJ-45 ports. The RJ-45 ports 1 to 4 use the same physical interface as the SFP ports 1 to 4. When a SFP is inserted, the corresponding RJ-45 port is disabled. For example, if a SFP is inserted in SFP port 1 then RJ-45 port 1 is disabled.
Hardware Reference 31 CompactFlash AT-9900 Series switches have a CompactFlash™ socket on their front panel. CompactFlash cards increase the flash memory available for file storage. You can manipulate compact flash files using the command line interface (CLI). Any type of data, including releases, patches, GUIs and configurations can be stored on CompactFlash cards. However, release, patch, and GUI files cannot be run directly from compact flash.
32 AT-9900 Series Switch A message notifies the user if the CompactFlash card is not compatible with the switch: Info (3106300): Compact flash card initialisation unsuccessful. When compact flash is in use, the CF (compact flash activity) LED on the front panel of the switch is green. Warning Do not remove the CompactFlash card when the card is being written to (that is, when the CF (compact flash activity) LED is lit). Doing so will corrupt data on the file being written.
