Table 7. Storage processor assembly LEDs (continued) LED Location State Blue and amber alternating (blue for 3 seconds) Blue and amber alternating at one second intervals Off Description System not initialized. A management IP address has not been assigned. Storage processor assembly in Service Mode. No fault has occurred, normal operation. Storage processor assembly power Green Green blinking Off Storage processor assembly is on (main power). Storage processor assembly is initializing a serial over LAN session. Storage processor assembly is off. Remove the SP assembly This procedure describes how to remove a SP assembly from the chassis. There are two SP assemblies. The top SP assembly is considered to be upside-down and mirrors the bottom SP assembly. The illustration shows the removal of the bottom SP assembly. The procedure for removing the top SP assembly is the same. About this task CAUTION: Do not remove a SP assembly while its "Unsafe to remove" LED is lit. The location of this LED is described in Embedded module LEDs. If the LED is lit, the SP assembly has not been properly shut down. CAUTION: Because SP assembly include cooling fans, they should be removed for as short a time as possible. Do not remove SP assemblies from a live system unless replacement parts are available. Steps 1. Rotate the power cable retention bail to the left (right for top power supply). Disconnect the power cable from the power supply. NOTE: If the I/O module and network cables are not already labeled, label them clearly for reconnecting later. Figure 71. Removing the power cable 2. Disconnect the network and all other cables from the back of the I/O modules and network ports on the SP assembly. 68 Service Procedures

Remove the SP assembly
This procedure describes how to remove a SP assembly from the chassis. There are two SP assemblies. The top SP assembly
is considered to be upside-down and mirrors the bottom SP assembly. The illustration shows the removal of the bottom SP
assembly. The procedure for removing the top SP assembly is the same.
About this task
CAUTION:
Do not remove a SP assembly while its "Unsafe to remove" LED is lit. The location of this LED is
described in
Embedded module LEDs
. If the LED is lit, the SP assembly has not been properly shut down.
CAUTION:
Because SP assembly include cooling fans, they should be removed for as short a time as possible. Do
not remove SP assemblies from a live system unless replacement parts are available.
Steps
1.
Rotate the power cable retention bail to the left (right for top power supply). Disconnect the power cable from the power
supply.
NOTE:
If the I/O module and network cables are not already labeled, label them clearly for reconnecting later.
Figure 71. Removing the power cable
2.
Disconnect the network and all other cables from the back of the I/O modules and network ports on the SP assembly.
